English title : 1 ,1,1 - Trichloro-2-methyl-2 - propanol; 1,1,1 - trichloro-2-methyl-2-Propanol; 1,1,1 - trichloro - tert-butyl alcohol; 2 - (trichloromethyl) - 2-propanol
< k traits Description : colorless crystals. Semi-containing molecular crystal water - and two-crystalline anhydrous exist. With half-molecular crystal water temperature 78 ° C were slightly soluble in water (1 in 250), soluble in ethanol (1:1), glycerol (1:10), ether, chloroform and volatile oil. Anhydrous type were 97 ° C melting point, boiling point of 167 ° C and 135 ° C (32.7kPa). Soluble in hot water, 1g can be dissolved in 1 ml of ethanol or 10ml glycerol, soluble ether, petroleum ether, acetone, chloroform, acetic acid, oils. Heating easy sublimation can be volatile with water vapor. It smells of camphor.
production methods : by the reaction of acetone and chloroform derived : chloroform, acetone by ration ingredients than to join reaction pot, cold to 8 ° C, stirring slowly by adding hydrogen under Potassium, control temperature does not exceed 15 °. Plus maintain the same temperature after mixing 2h, heated, filtered and the filtrate was concentrated to not run out droplets far. Stop heating, cooling to 25 ° C by adding ice water, stirring, precipitated crystallization centrifugal crystallization centrifugal separation, cake washed with distilled water to date no chlorine ion. 60-65 ° C in about 2 hours drying, filtration and packaging. The yield was 56% (or chloroform). material consumption fixed : chloroform 1247kg / t, acetone 1688kg / t, potassium hydroxide 285kg / t.
purposes : main raw materials for medicine, producing anti-corrosion products antiemetic, local analgesic. Its aqueous 1% or 5% -10% ointment may Sterilization. Can also be used for organic synthesis.
