| titleOfInvention | Preparation method of mercaptoacetic acid-2-ethylhexyl in molten salt hydrate |
| abstract | The invention relates to a preparation method of mercaptoacetic acid-2-ethylhexyl ester in molten salt hydrate, and belongs to the technical field of organic synthesis. The steps of distillation and concentration of the acidified solution of thioglycolic acid are included; the steps of adding CaCl 2 to obtain a concentrated solution of distillation containing molten salt hydrate; the step of esterification using molten salt hydrate as a reaction medium; Hexyl ester step. The invention integrates the separation of thioglycolic acid, the treatment of tail-extraction wastewater, and the esterification reaction, greatly simplifies the production process, can effectively separate water and solid salt, and the content of organic matter in water and solid salt is low, and the separated water It can be reused, and the solid salt can also be used as a by-product. The invention greatly reduces the side reaction in the production process of thioglycolic acid-2-ethylhexyl, improves the yield and reduces the production cost. |
