1,2,5,6-四氢苯酐的合成研究

Study on Synthesising 1,2,5,6-Tetrahydrophthalic Anhydride

顺丁烯二酸酐与１，３－丁二烯通过Ｄｉｅｌｓ－Ａｌｄｅｒ反应制备１，２，５，６－四氢苯酐，产品收率在９８％以上，熔点为９８～１００℃。

1,2,5,6-Tetrahydrophthalic anhydride is prepared by the Diels-Alder reaction of maleic anhydride with 1,3-butadiene The yield of product is more then 98% and melting point is 98～100℃
