27532-96-3 - Reference Information
| application | tert-butyl glycine hydrochloride is not only an important chemical raw material, but also widely used in drug synthesis and has good development prospects. |
| preparation | 1400L t-butyl acetate, 105KG glycine and 180KG perchloric acid were added dropwise at a uniform speed in a 2000L reaction tank. React at 0-10 ℃ for about 48-72 hours. TLC monitors the reaction during the reaction. After the glycine reaction is more than 90%, use 4 N sodium hydroxide aqueous solution to adjust the PH6.5 -7.5 to separate the organic layer. The water layer continues to be extracted with tert-butyl acetate. After the water product is basically extracted to the 95%, all product layers are combined, washed with brine to TLC purity to obtain 1500L tert-butyl glycine/tert-butyl ethyl ester solution, concentrate and recover tert-butyl ethyl ester to obtain 180KG of tert-butyl glycine, add 100L of ethyl ethyl ester, pass hydrogen chloride to PH0.5, stir and cool the cold crystal, and centrifugally wash to obtain 182KG of tert-butyl glycine hydrochloride. |
