Method of obtaining ethoxychlorvanadate |
| abstract |
The invention relates to the production of diethoxychloro-panadate, a component of the polymerization of olefins. The goal is to simplify the process. It is carried out by the reaction of vanadium trichloroxide (VOCL 3 ) with orthoformic acid triethyl ester or triethoxysilane (molar ratio 1: 0.8-0.9) or with trimethyl ethoxysilane (molar ratio 1: 2.4-2.6) at 70- 73 ° C and simultaneous distillation of low-boiling substances. These conditions allow the elimination of sodium ethoxide and the reduction of non-recyclable-NACL contaminated with vanadium compounds. 1 tab. |
