A process for the continuous production of an alcohol from an organic halide, metallic magnesium and an organic carbonyl compound according to the Grignard reaction, which process comprises continuously supplying a portion of an intended amount of the organic halide and an intended amount of the metallic magnesium with an inert solvent to a first reaction zone whereby the reaction between the organic halide and the metallic magnesium proceeds to give the Grignard reagent, and continuously passing the reaction mixture comprising the Grignard reagent and the unreacted metallic magnesium from the first reaction zone to a second reaction zone to which the remaining portion of the organic halide and an intended amount of the organic carbonyl compound, optionally with an inert solvent, are continuously supplied whereby the Grignard reaction proceeds to give the Grignard reaction product, followed by subjecting the reaction mixture comprising the Grignard reaction product from the second reaction zone to hydrolysis to give the alcohol.
一种根据格氏反应由有机卤化物、金属镁和有机羰基化合物连续生产醇的工艺,该工艺包括将一部分预定量的有机卤化物和预定量的金属镁与惰性溶剂一起连续供应到第一反应区,在第一反应区中有机卤化物和金属镁进行反应生成格氏试剂、将包含格氏试剂和未反应的金属镁的反应混合物从第一反应区连续通入第二反应区,在第二反应区连续通入剩余部分的有机卤化物和预定量的有机羰基化合物(可选择使用惰性溶剂),从而进行格氏反应,得到格氏反应产物,然后将包含格氏反应产物的反应混合物从第二反应区进行水解,得到醇。
