【摘要】 <正> Bogojawlensky等曾以无水硫酸铜、锌、锰、镍等盐催化酯化合成一系列羧酸乙酯.近年来也有类似报道、如等以无水硫酸铜催化合成酚类的羧酸酯;Broniarz等人以无水硫酸铁催化合成羧酸甲酯;Constantin以无水硫酸铜催化合成乙二醇单乙酸酯等.我们发现固体硫酸盐水合物与羧酸、醇加热回流,也有催化酯化作用.本文报道用硫酸亚铁、钴、镍、铜、锌等盐的水合物催化乙酸与脂肪醇的酯化,得率为:甲酯更多还原

【Abstract】 The solid hydrates of metallio sulfate （FeSO₄·7H₂O, CoSO₄·7H₂O, NiSO₄·6H₂O, iSO₄·7H₂O, CuSO₄·5H₂O and Zn SO₄·7H₂O） were used as catalysts for esterification of arious alcohols with glacial acetic acid. The yields are shown in Table 1 （Chinese text）. ithout the catalyst, for example, the yields of ethyl acetate and n-butyl acetate were 21.0～2.0% and 24.0～26.5%, respectively.更多还原
