Abstract
Using p-methoxy benzoic acid,dichloro sulfoxideand L-tartaric acid as starting materials,L-(-)-di(p-methoxy) tartaric acid was synthesized via acyl chloride reaction,esterification,anhydridization and hydrolysis.The effect of reaction time,the amount of p-anisoyl chloride,hydrolysis system and hydrolysis time on the yield were studied.The optimum reaction conditions were as follows:n(L-tartaric acid) ∶n(o-toluoyl chloride) 1 ∶2.4,reaction time 4 h,taking acetone-water(V/V=1 ∶1) as hydrolysis system and hydrolysis time was 3 h.The total yield of the target product was 88.0%.
