The process for the production of carnitine hydrochloride which includes reacting a .alpha.-haloacetoacetanilide having the formula: XCH.sub.2 COCH.sub.2 CONYC.sub.6 H.sub.5 where X is a halogen atom and Y is a hydrogen atom, a phenyl group, a benzyl group or an alkyl group having 1 to 8 carbon atoms, with trimethylamine, a .gamma.-trimethylammonium acetoacetanilide halide resulting. The .gamma.-trimethylammonium acetoacetanilide halide, is hydrogenated, a .gamma.-trimethylammonium-.beta.-hydroxybutyric acid halide resulting. The .gamma.-trimethylammonium-.beta.-hydroxybutyric acid halide is converted by means of aqueous hydrochloric acid into the carnitine hydrochloride.
生产肉碱盐的过程包括将具有以下公式的α-卤代乙酰乙酰苯胺反应:XCH2COCH2CONYC6H5,其中X是卤素原子,Y是氢原子、苯基、苄基或具有1至8个碳原子的烷基,与三甲胺反应,产生γ-三甲基铵乙酰乙酰苯胺卤化物。γ-三甲基铵乙酰乙酰苯胺卤化物被氢化,产生γ-三甲基铵-β-羟基丁酸卤化物。通过水盐酸的方式将γ-三甲基铵-β-羟基丁酸卤化物转化为肉碱盐。
