1. Sulfuric acid water method by isobutene and sulfuric acid hydration: generally by the extraction of butadiene after the mixed C4 fraction as the raw material, at 0.7MPa; Under the condition of 15ºC, 60-70 sulfuric acid is used to esterify, 99 isobutene is absorbed to produce tert-butyl sulfate, and then hydrolyzed to produce tert-butanol, and the finished product is obtained by water vapor desorption, water removal, purification and purification. 2. Ion exchange resin water mixed C4 fraction and soft water in the presence of cation exchange resin hydration to produce tert-butanol, stratified; Concentrate and get 85 tert-butanol. 3. Propylene; 4. Direct water method with high concentration of heteropoly acid aqueous solution as catalyst. The isobutene in the mixed C-4 was selected to hydrate to produce tert-butanol.
1, often replace n-butanol as a solvent for paint and medicine. Used as fuel additive for internal combustion engines (to prevent carburetor from freezing) and antiknock agent. As the intermediate of organic synthesis and the alkylation raw material for the production of tert-butyl compounds, methyl methacrylate, tert-butyl phenol, tert-butylamine can be produced for the synthesis of drugs and spices. Isobutene with purity of 99.0-99.9% can be prepared by dehydration of tert-butanol. It is used as solvent for industrial detergents, pharmaceutical extractant, insecticide, solvent for wax, cellulose ester, plastic and paint, and is also used in the manufacture of denatured alcohol, spices, fruit essence, isobutylene and so on.
2, determination of molecular weight of the solvent and chromatographic analysis of reference substances. In addition, it is often used instead of n-butanol as a solvent in coatings and medicine.
3, used as solvent, chromatographic analysis standard material.
4, used for spice synthesis.
5, used as fuel additive for internal combustion engine (to prevent carburetor icing) and antiknock agent. As the intermediate of organic synthesis and the alkylation raw material for the production of tert-butyl compounds, methyl methacrylate, tert-butyl phenol, tert-butylamine can be produced for the synthesis of drugs and spices.
