固体酸CuCo2S4催化制备呋喃基二酯化合物
Preparation of furfuran-based diester chemicals catalyzed by CuCo2S4 solid acid
摘要
Abstract
Furfuran-based diester chemicals were prepared through the esterification reaction between 2,5-bishydroxymethyl tetrahydrofuran(THFDM)and fatty acids with different chain lengths(n-butyric acid,n-decanoic acid,and palmitic acid)with a novel type of porous solid acid MOF catalyst(CuCo2S4).The effects of alcohol/acid ratio,catalyst dosage,reaction temperature and time on the esterification reaction were investigated.The results showed that the conversion efficiencies of n-butyric acid,n-decanoic acid and palmitic acid were as high as 84.57％,94.22％and 87.20％,respectively,under the conditions of 1:1 molar ratio of THFDM to fatty acid,1.25％dosage of catalyst(on the basis of THFDM)at 140 ℃ for 7 h.The results of FT-IR and 13C NMR spectra of purified products showed that the products possessed the symmetric diester structure,and their basic physicochemical properties indicated the potential application of 2,5-tetrahydrofuran dibutyrate in the field of lubricating oil additives.关键词
