| titleOfInvention | Method for co-synthesis of chloroalkanes and chloroform on solid catalyst |
| abstract | FIELD: chemistry. ^ SUBSTANCE: invention relates to methods of converting chlorohydrocarbons, specifically to methods for simultaneous production of chloroform and chloroparaffins. Described is a method for co-synthesis of chloroform and chloroalkanes from tetrachloromethane and alkane, which is carried out in liquid phase in the presence of a solid catalyst which is a product of reacting copper chloride, 3-chloropropyl trimethoxy-siloxane, tertiary amine or derivatives of imidazole and silica gel. The tertiary amine used is compounds of general formula R1R2R3N, where R is methyl, ethyl, propyl or isopropyl. The imidazole derivative is methyl- or ethyl-imidazole. Content of copper in the catalyst is equal to 1.5-2 wt %. The process for co-synthesis of chloroform and chloroalkanes is carried out at temperature 160-190C and contact time of 3-5 hours in the presence of an organic additive selected from C2-C4 alcohols. ^ EFFECT: simplification of the process owing to exclusion of the step for purifying the end product from catalyst conversion products and resinous substances and possibility of using the catalyst many times. ^ 2 tbl, 14 ex |
