에틸알미늄세스키클로라이드

생산 방법Ethyl chloride and aluminum could used as starting metarials to synthesize Ethylaluminum sesquichloride. A 9.5 × 10-2 m3 closed steel reactor, fitted with a reflux condenser and equipped for vacuum distillation of product, was first purged with nitrogen. After addition of 13.6 kg of aluminum powder and a catalyst mixture composed of 3.6 kg diethylaluminum chloride and 410 g iodine, the reactor contents were stirred and heated slowly to 130 ℃. The temperature was maintained at 120 – 150 ℃ during addition of 50 kg ethyl chloride over a period of 3 h. The product can be flash distilled under vacuum, or it can be drained from the reactor and clarified by settling or by filtration of black residual metal solids. Iodine can be omitted from the procedure, in which case the induction period may be increased.
