| overview | petroleum jelly is a refined stone oil mixed with residual oil, wax paste and lubricating oil. it is an important lubricant for medicine, daily chemical industry, fine chemical raw materials and precision instruments. The main products of petroleum jelly in our country are ordinary petroleum jelly, industrial petroleum jelly and pharmaceutical petroleum jelly. Ordinary petroleum jelly is suitable for preparing various ointments and softeners for dark rubber products. Industrial petroleum jelly can be used for rust prevention of metal products and general mechanical parts, lubrication of light-load machinery, leather wetting agent and rubber softener. Vaseline products in China are mainly concentrated in pharmaceutical vaseline, which is divided into pharmaceutical white vaseline and pharmaceutical yellow vaseline. Pharmaceutical Vaseline is mainly used to prepare ointment, skin protective cream and cosmetic raw materials, and can also be used as antirust and lubricating materials for medical devices and precision instruments. |
| performance | white or yellowish homogeneous paste, almost odorless and tasteless, is a mixture of liquid and solid paraffin hydrocarbons. The relative density is 0.815~0.830, the viscosity is 0.01~0.02Pa s (100 ℃), the flash point is greater than 190 ℃ (open type), and the dropping point is about 37~54 ℃. Soluble in ether, petroleum ether, various fatty oils, benzene, carbon disulfide, chloroform and turpentine, insoluble in ethanol, almost insoluble in water. It is heated into a transparent liquid, which can fluoresce in the dark after being irradiated by ultraviolet rays. |
| use | because vaseline has the characteristics of colorless, odorless, chemically inert, semi-solid, lipophilic and good adhesion, it is suitable for manufacturing hair care cream, hair conditioner, eye shadow cream, lipstick, hair wax and other substrates. Medicine Vaseline, which can be compatible with almost all drugs without changing the drug, can be used as a matrix for ointments and is widely used. Add alcohols such as decadanol, decane alcohol, cholesterol and other alcohols to petrolatum, warm and melt and fully stir to produce hydrophilic petrolatum. Hydrophilic Vaseline is a highly permeable and stable ointment substrate with little irritation. This kind of ointment matrix can be used alone for dry rash, erythema, papules and other diseases, especially for the removal of blood scabs and desquamation. Vaseline can also be used as an emulsifier to be compatible with cholesterol, which is non-ionic, so it can be compatible in a wide range. In addition, due to its absorption, it can be compatible with liquid drugs or aqueous solutions of drugs. Industrial petroleum jelly is used as rubber softener, metal device anti-rust, anti-rust grease raw material. |
| preparation method | 1. acid-clay method acid-clay method is a traditional petroleum jelly production method, which is still in use at home and abroad. The process is to add sulfuric acid with a concentration of more than 98% to the reaction kettle and mix the raw materials according to about 60% of the amount of raw materials, keep the reaction temperature at 70 ℃, separate the acid residue after the reaction, and dilute with alcohol to further remove the acid residue. The acid-treated oil is then decolorized in another clay refining tank at about 140 ℃, and then filtered to obtain the product. The characteristic of the acid-clay method is that it can produce products with better quality, the amount of polycyclic aromatic hydrocarbons can reach the pharmaceutical level, and other relevant indicators can also meet the quality indicators of the pharmacopoeia. This is the reason why the traditional process can exist for a long time. The main disadvantages of petroleum jelly refined by acid-clay method are that the yield of the target product is too low (about 50%) and a large amount of acid residue that is difficult to use, which seriously pollutes the environment and has high production cost. 2. Aluminum trichloride method in China began to use aluminum trichloride method instead of acid-clay method to produce vaseline in the 60s. The specific process is as follows: the raw materials are dehydrated and reacted with aluminum trichloride in a reaction kettle at a reaction temperature of 130-140 ℃. After the reaction, the oil continues to neutralize and precipitate in the neutralization tank with lye, and then adsorb and refine the clay in the decolorizing tank after the slag is removed. The reaction temperature is about 120 ℃, and the filtered refined oil is commercial vaseline. The product yield of petroleum jelly obtained by aluminum trichloride method is higher than that of acid-clay method, and the consumption index is reduced, but the quality is slightly worse than that of petroleum jelly obtained by acid-clay method. There is a big gap between the quality level of petroleum jelly obtained by aluminum trichloride method and medium pressure hydrogenation and high pressure hydrogenation in terms of color, transparency, and content of aromatic hydrocarbons. 3. Hydrogenation Hydrogenation Vaseline is a new process for the production of Vaseline, which is generally carried out abroad under the conditions of 10, 20 or 30MPa and low liquid space-time velocity. The process converts the useless components in the raw material into effective components after reacting, so a product yield of nearly 100% can be obtained. However, the aluminum trichloride method or the acid-clay law turns the useless components into waste residue and removes the effective components from the slag, thus reducing the product yield. Due to the product yield, the refining depth of aluminum trichloride method or acid-clay method is also limited, thus limiting the further improvement of product quality. Therefore, the hydrogenation method is better than the acid-clay method and the aluminum trichloride method in terms of product yield or quality. (2015-12-28) |
