n-Propyl-d7 Alcohol - References
| propanol isomer | n-propanol and isopropanol are two kinds of isomers of propanol, which have the chemical properties of aliphatic primary alcohols, mainly used as solvents and organic synthesis intermediates, in many cases can replace the lower boiling point of ethanol, for the production of plasticizers, spices, pharmaceuticals, pesticides, cosmetics and feed additives. N-propanol reacts with propylene oxide to form a Polyether, which is a surfactant. In the United States, about 40% of N-propanol is directly used as a solvent or synthetic propyl acetate for Coating solvents, printing inks, cosmetics, etc.; 40% of N-propylamine as an intermediate for the production of pharmaceuticals and pesticides; 20% for the production of feed additives, synthetic spices. The world production of N-propanol was about 13kt in 1979. propionaldehyde is industrially prepared from ethylene, hydrogen and carbon monoxide by carbonyl synthesis, and then propionaldehyde is hydrogenated to produce N-propanol under the catalysis of cobalt, it is also possible to separate n-propanol from the oxidation liquid of a lower alkane. The reaction equation for preparing N-propanol by hydrogenation of propionaldehyde is as follows: The catalysts used include carbonyl compounds of cobalt or rhodium, ruthenium complexes, skeleton catalysts (such as nickel and copper), etc, the most common is a framework catalyst. The hydrogenation reaction may be homogeneous or heterogeneous. The latter is divided into Liquid Phase Hydrogenation and gas phase hydrogenation. Nickel-based catalysts are mostly used for liquid-phase hydrogenation; Copper-based catalysts are mostly used for gas-phase hydrogenation, and the trend in recent ten years is to use copper-zinc oxide catalysts. The reactors are fixed-bed reactors, Slurry reactors, and trickle-bed reactors. The above information was compiled by Tong Tong. |
| isopropyl alcohol | Isopropyl alcohol is the simplest secondary alcohol, its chemical properties with n-Propyl alcohol (primary alcohol) although there are alcohol, but this product and N-propanol and there are many differences. The hydrogen on its hydroxyl group can be substituted by sodium (or potassium) to generate sodium alkoxide and simultaneously release hydrogen gas; React with hydrogen halide acid to generate halogenated isopropyl compound; And form ester with organic acid; reaction with ethylene oxide, can produce isopropanol alcohol ether; In the catalyst, can be dehydrogenated to produce acetone; In the liquid phase oxidation of acetone and hydrogen peroxide; Under the action of catalyst and acrolein hydrogen exchange, allyl Alcohol and acetone were generated. The physiological role of this product is the same as that of N-propanol, rat oral LD505800mg/kg. The use of isopropanol is more extensive than that of N-propanol, which is due to the chemical activity of this product is greater than that of N-propanol. Used as a solvent, can be miscible with water and aromatic hydrocarbons, used as a solvent more extensive than N-propanol; This product can be dehydrogenation of acetone, which is not n-propanol; Isopropanol aqueous solution, can make the freezing point of water, for example: containing isopropanol 15%(volume fraction), the freezing point of water -3.3 ℃, 25% -6.7 ℃, 30% -8.3 ℃, 35% time -11.1 ℃, 40% time -13.0 ℃, 45% time -17.8 ℃, 50% time -23.0 ℃ and 60% time -32 ℃. Using this feature, isopropyl alcohol is added to the fuel oil of automobile and airplane as antifreeze agent; It can be added to the water tank to prevent icing; It is also used as perfume, isopropyl alcohol is temporarily allowed to use in China GB2760-1996; also used as pesticides and pharmaceutical raw materials, the production of thymol and rust remover; Is also an important intermediate in organic synthesis.
