摘要:
Process, which is feasible on a commercial scale, for the production of gamma-butyrobetaine. For this purpose, butyrolactone with hydrogen chloride and an alcohol is converted to the chlorobutyric acid ester, the trimethylammonium butyric acid salt is formed with trimethylamine and then saponified to the end product.
