Check all production methods and purposes
Production methods
By the gallic acid and dimethyl sulfate methylation reaction.Water, gallic acid, dimethyl sulfate to join reaction pot, add sodium hydroxide solution under 15 to 35 ℃, 40 ℃ stir around half an hour.Add the second batch of dimethyl sulfate, around 40 ℃ to add sodium hydroxide solution pH of 8 to 9.Continue after 1 h of reaction, cooling, filtering, washing, drying, preparation base benzoic acid methyl ester, yield of above 90%.The methylation, the esterification reaction, also can use tetrabutyl ammonium bromide as phase transfer catalyst, in the water and chloroform.The goods tannic acid can also be used as raw material, or by three, four, five - preparation base benzoic acid and methanol esterification to making
use
Is used as pharmaceutical intermediates, anxiolytics sibutramine lamictal, intestines and stomach medicine maleic acid trimebutine, etc. The main raw material.
