Research progress of homogeneous esterification of starch
摘要
Abstract
As an important kind of starch derivatives,starch esters have attracted much attention with the intensive need of renewable resources due to their good thermoplasticity and thermostability. However,because of its semi-crystalline structure,starch is insoluble in water and most organic solvents,which has limited broader application of starch esterification with low esterification and low degree of substitution. Nevertheless,several kinds of solvents for starch have been used as homogeneous systems for starch modification. In this review,development of modified starch in the homogeneous systems in the recent 30 years is summarized and 49 references are cited. Research progress of starch esters in dimethyl sufoxide (DMSO),LiCl/N,N-dimethylacetamide (DMA/LiCl),and ionic liquids(ILs) is presented. The influence of catalyst,reaction temperature and concentration of esterifying agent on degree of substitution is discussed. Structure and thermodynamic properties of starch derivatives show superiority of homogeneous systems by comparing with natural starch or heterogeneous products. Finally,some problems that need urgent solution and future development of starch homogeneous esterification modifications are suggested.关键词
