Make a summary for having discussed that the dry law and microwave do law along butylene diacid Shan ester composing amylum. Two estolide are that the ester melts an agent take amylum as raw material , with smooth butylene , the ester carrying out the solid room's spends reaction under the situation of there being no menstruum,ester composing smooth amylum butylene diacid Shan, and by having optimized reaction condition , having improved reaction efficiency. Have compared by doing law and the microwave do law reaction result , have testified a microwave doing law have shortened reaction time tremendously , have improved reactive replace and reaction efficiency. With amylum and amylum, along butylene diacid Shan ester, as flocculant, suspension liquid has carried out the flocculation experiment on kaolin. But do not have the flocculation ability nearly by testifying the amylum not having changed nature comparatively,that amylum obeys the butylene diacid Shan ester is fine flocculant of one kind of effect. Keywords: Change nature amylum; Amylum obeys the butylene diacid Shan ester; Do law combining
