Reaction Conditions:
with copper(II) sulfate in toluene for 4 h;Autoclave;Large scale;Reagent/catalyst;
Steps:
5
To the 3000 L autoclave, 450 kg of T-tartaric acid and 600 L of toluene were added. 2 kg of copper sulfate was added with stirring. 880 kg of benzoyl chloride was added dropwise and the reaction was continued for 4 hours. The reaction was continued for 4 hours, Dibenzoyl tartaric acid anhydride 1211.7kg, put it into 5000L reactor, add water and toluene 1211.7kg, heated to reflux, keep 3 hours, cooling to room temperature discharge, rejection of L-dibenzoyl tartaric acid 1059.8kg.The L-dibenzoyl tartaric acid obtained in this example was subjected to TEM test. The test structure was shown in Fig. 5, and it was found that the purity of the product L-dibenzoyl tartaric acid was 99.09% and the total yield was 97.2%.
