production method | 1. The dried HCH was heated in a pyrolysis kettle to obtain trichlorobenzene, and a large amount of hydrogen chloride was by-produced. Alkali hydrolysis of Six Six Six non-toxic body and milk of lime heat that is obtained trichlorobenzene, while by-products a large number of calcium chloride solution. Trichlorobenzene obtained by the above two methods is 1,2, 4-trichlorobenzene; 1,3, 5-trichlorobenzene; 1,2, 3-trichlorobenzene three kinds of isomers mixture, 1,2,4-trichlorobenzene as the main component. The content of 1,2, 4-trichlorobenzene in trichlorobenzene produced by milk of lime method is more than 75%, and 1,2, 3-trichlorobenzene accounts for about 20%. |
