Chemical properties Colorless flammable liquid that has a distinctive camphor-like odor when burned. Soluble in 8 times water, miscible with ethanol, ether, benzene, chloroform, glycerin and oil. The aqueous solution is neutral to litmus. Uses As a raw material for synthetic spices and pesticides, and also an excellent solvent, tert-amyl alcohol is mainly used in the production of new pesticide powder, pinadone, triazolone, triazolol, seed protectant, etc. It can also be used for the synthesis of indene musk and as a color forming agent for color film. The intermediate product of the production of tert-amyl alcohol is also a useful pharmaceutical intermediate and terpene flavor intermediate, and is used in the manufacture of acid corrosion inhibitor, viscosity stabilizer, viscosity reducer, and for the manufacture of nickel plating, copper plating polish, chlorinated hydrocarbon stabilizer, etc. Production method (1) Acetone, acetylene as raw materials, through acetylene, hydrogenation and obtained. Acetylene is dissolved in liquid ammonia, mixed with acetone and catalyst, and then sent to the acetylene reactor. The reaction liquid is flash steamed to separate the unreacted acetylene and ammonia, and the unreacted acetone is steamed out by Chemicalbook. The obtained methylbutyneol enters the hydrogenation reactor to react and produce tert-amyl alcohol. (2) It is made of isopentene and water. (3) It is prepared by fractionation of mixed alcohol produced by chlorination and hydrolysis of pentane. The raw material pentane is first dehydrated with anhydrous hydrogen chloride, then evaporated and mixed with chlorine gas into the reactor at a reaction temperature of 250-300ºC. The product was separated by four distillation columns to obtain pentane chloride. Using sodium oleate as catalyst, the chloropentane was hydrolyzed with sodium hydroxide solution. The crude amyl alcohol was separated from water and distilled to obtain amyl alcohol containing 59% primary alcohol, 36% secondary alcohol and 5% tertiary alcohol. By using acetone and acetylene as raw materials, products with a purity of 99% can be obtained. Raw material consumption quota: acetone 1040kg/t, calcium carbide 1500kg/t, hydrogen (99.5%) 650m3, liquid ammonia 135kg/t, potassium carbonate 340kg/t.
