Summary:
Oil hydrogenation is the process of adding hydrogen to the double bond of triacylglycerol using reducing nickel and other metals as catalysts. However, in the hydrogenation process, the isomerization product-trans fatty acids (TFAs) will be produced to varying degrees. Therefore, the academic community has been studying how to reduce the content of TFAs in the hydrogenation process, especially the preparation and performance of various catalysts in catalytic hydrogenation. By preparing zirconium dioxide (ZrO2) supported precious metal platinum catalyst, soybean oil was hydrogenated under industrial conditions and compared with Raney nickel catalyst for its activity, reaction selectivity and TFAs content. The precious metal platinum supported catalyst was prepared by impregnation-reduction method, and the catalyst was physically and chemically characterized by commonly used characterization methods such as XRD,TEM,BET,ICP, etc. At the same time, soybean oil was catalyzed for hydrogenation under industrial hydrogenation conditions. The activity, selectivity and TFAs content of each catalyst were compared, and the quality indexes of hydrogenated oil such as acid value and melting point were further compared. The results showed that the activity of ZrO2 supported noble metal platinum catalyst was significantly higher than that of nickel catalyst, and the trans acid content produced when the iodine value was about 70 was 25.48g/100g soybean oil, which was lower than that produced by nickel catalyst (31.42g/100g soybean oil). After hydrogenation of supported platinum catalyst, the acid value of grease is stable and less than 1.0 mgKOH/g; The sliding melting point of grease increased significantly, reaching 45.08 ℃. Under the conditions of industrial hydrogenation, ZrO2 supported platinum catalyst is a typical mesoporous material, with small metal particle size, good metal dispersion, high activity, low TFAs content and other advantages.

Summary:
The present invention provides a method for hydrogenating soybean oils and fats without adding hydrogen to ultrasound. The hydrogen donor provides a fast mass transfer rate of H without the addition of hydrogen. A large amount of trans fatty acids (TFAs) are produced during the hydrogenation of fats and oils, and the intake of TFAs in the body will have a bad effect on the human body. The addition of ultrasound in the reaction process accelerates the speed of the chemical reaction, and the ultrasound causes the substance to undergo severe forced vibration and accelerates the diffusion of the substance. The preparation method includes: weighing a certain amount of soybean oil in a reactor, adding a certain concentration of ammonium formate solution and a certain proportion of NiAg catalyst, turning on the ultrasonic device, reacting at a constant temperature for a period of time, after the reaction is over, adding an appropriate amount of n-hexane is diluted, and after the water phase is separated, vacuum filtration is carried out to separate the catalyst to obtain hydrogenated grease. At this time, the iodine value of hydrogenated soybean oil is 92

Summary:
aiming at the disadvantages of slow reaction speed and large amount of trans fatty acids in conventional low-pressure hydrogenation of soybean oil, the hydrogenation conditions of soybean oil were optimized and improved. The effects of hydrogen pressure, reaction temperature, reaction time and stirring speed on iodine value and trans fatty acid content in hydrogenated soybean oil were mainly investigated. Through orthogonal test, the optimal hydrogenation reaction conditions were optimized as follows: hydrogen pressure 2.5MPa, reaction temperature 110 ℃, reaction time 120min, stirring speed 300r /min, catalyst addition 1.5%. Under this process condition, the content of trans fatty acid in the hydrogenated product is 17.387%. Compared with conventional hydrogenation, the content of trans fatty acid is reduced by about 16%.

| overview | hydrogenated soybean oil is soybean oil obtained from the seeds of legume soybean (Glycine soya Bentham), which is refined, decolorized, hydrogenated and deodorized. It is included in the European Pharmacopoeia and the United States Pharmacopoeia. It is a pharmaceutical excipient. The medicinal quality standard of hydrogenated soybean oil has not been studied in China. foreign name: Hydrogenated soybean oil application: pharmaceutical excipients, lubricants. |
| properties | this product is a white to light yellow lump or powder, which is transparent and light yellow liquid after heating and melting. Soluble in dichloromethane or toluene, insoluble in water or ethanol. |
| melting point | 66 ℃ ~ 72 ℃ (Chinese pharmacopoeia 2005 edition, appendix vi c, second method). Figure 1: Hydrogenated soybean oil |
| identification | in the chromatogram recorded under fatty acid composition, the retention time of methyl palmitate and methyl stearate peaks in the sample solution should be consistent with the retention time of the corresponding control substance respectively. |
| Determination of | Fatty acid composition: Hydrogenated soybean oil mainly contains palmitic acid and stearic acid, and the remaining 6 fatty acids are impurities that need to be controlled. Among them, stearic acid and oleic acid are fatty acids with 18 carbon atoms. The retention time of the two in the chromatographic column is relatively close and it is not easy to separate. The European Pharmacopoeia detection method is potassium hydroxide methanol saponification and extraction, without reflux of 14% boron trifluoride methanol solution, the test product was foamed after potassium hydroxide methanol saponification during the test, making separation and extraction difficult. At present, the detection method used in Chinese Pharmacopoeia is to determine the fatty acid composition in hydrogenated soybean oil by gas chromatography and temperature programmed by using boron trifluoride as esterifying agent. Results Eight fatty acids could be separated at baseline within 20 min with good linearity, precision and reproducibility. This method is simple and quick, and can be used for the determination of fatty acid composition in hydrogenated soybean oil. Trans fatty acids [3] Refined soybean oil is dominated by polyunsaturated fatty acids, and the content of trans fatty acids is less, mostly trans -18-carbon soybean oil polyene fatty acids; the content of polyunsaturated fatty acids in hydrogenated soybean oil Significantly reduced, the content of trans fatty acids increased significantly, about 10 times the content of trans fatty acids in refined soybean oil, mostly trans -18-carbon monoene fatty acids. The CP-Sil88 strong polar capillary column gas chromatography method can be used for qualitative and quantitative analysis of cis, trans-isomeric and position-isomeric fatty acids in refined and hydrogenated soybean oil, and the main cis and trans fatty acids are The baseline separation is achieved, and the separation of nickel is also achieved for various position-isomeric fatty acids. [4] No preservatives and antioxidants are added to hydrogenated soybean oil. Nickel is used as a catalyst in the hydrogenation process. Therefore, the residue of nickel should be controlled in the quality standard. Refer to Chinese Pharmacopoeia Appendix IV D Atomic Absorption Spectrophotometry Second Method Standard Addition Method. Preparation of test sample solution: take 5.0g of hydrogenated soybean oil into a crucible, slowly heat to carbonization, burn to white ash at 600 ℃, cool, wash the residue twice with dilute hydrochloric acid to a 25mL volume 241 flask each time, add 0.3mL nitric acid to dissolve, and dilute to scale with water. Preparation of control solution (main standard solution): accurately measure the standard nickel solution and dilute it to 100 μg/L with water. Take 0.0mL, 1.0 mL, 2.0mL and 3.0mL respectively, add 2.0mL of the test solution, and dilute to 10.0mL with water. The determination method can be determined by graphite furnace atomic absorption spectrometry, corrected by Seyman background, and determined by standard addition method. The drying time and ashing temperature are optimized, the operation is simple, the result is stable and accurate, and the sensitivity is high, which can effectively control the quality of the pharmaceutical excipient. |
| apply | lubricants for tablets and capsules, with a concentration of 1-6%, often shared with talcum powder, and can also be hot melted in liquid paraffin and sprayed on dry particles. It can also be used as an auxiliary adhesive when produced in tablets. Skeleton materials are commonly used in lipophilic controlled-release preparation systems and can also be used as coating aids in controlled-release preparations. Hydrogenated soybean oil can be used as a viscosity modifier for oily liquid preparations or semi-solid preparations. Fillers are used in liquid and semi-solid fillers of gelatin hard capsules and soft capsule preparations. Lubricating oil [5] uses tertiary soybean oil as raw material, and uses supercritical CO2 fluid in the hydrogenation reaction. No organic solvent is added during the test. It is a "green and environmentally friendly" preparation method. Through single factor and orthogonal tests, it is concluded that the optimal conditions for preparing lubricating base oil from soybean oil under supercritical CO2 are as follows: Pd /C catalyst dosage 0.06%, reaction time 45 min, reaction temperature 50 ℃ ,CO2 pressure 5.5 MPa, hydrogen addition to total pressure 9 MPa, stirring speed 200 r/min. Under these conditions, the iodine value (I) of hydrogenated soybean oil is 88.20g /100g, the viscosity is 9.89 Pa • s, the peroxide value is 5.6 mmol / kg, and the acid value (KOH) is 0.68 mg/g. The produced lubricating oil can be used in the food processing process. The part where the material and lubricating oil are in direct contact is a renewable, green and environmentally friendly lubricating oil. Figure 2: Lubricating oil |
