标题:一种牛奶内酯香料的连续化合成方法
摘要:本发明属于合成香料技术领域,具体涉及一种牛奶内酯香料的连续化合成方法,包括在碱水作用条件下进行羟醛缩合反应,接着经加氢反应,Baeyer‑villiger氧化,经酸连续化水解,脱水得到牛奶内酯香料;所述羟醛缩合反应包括:将部分作为底料的环己酮与碱水混合均匀,加热处理,滴加剩余量环己酮与正丁醛的混合物,边滴加边搅拌,且在滴加结束后继续搅拌,保温反应至正丁醛的含量在1%以下结束反应;静置后分出油层,收集水层并回收套用;收集油层经过水洗处理后转入蒸馏釜中蒸馏回收过量的环己酮套用,收集釜底的缩合产物;本发明通过将环己酮以不同的方式加入,提高了该羟醛缩合反应的产率;并且,在本发明的反应温度条件下,能够一步得到羟醛缩合的产物.

标题:Enzyme-catalyzed synthesis of macromolecules in organic solvents

摘要:A method is described for a simple, fast and efficient synthesis of homopolymers and copolymers by the enzymatic ring opening polymerization of lactones and lactides. The enzyme used is an ion paired protease. The advantage of this enzymatic system is in using small amount of enzyme per monomer and lower reaction time. Homopolymers and copolymers are synthesized with molecular weights between 1000 and 4600 daltons, and dispersity as low as 1.1. The monomer conversion after 4 days, for reactions catalyzed by protease S, has reached 100%. Different initiators are used to control the rate and degree of polymerization. Synthesis of block copolymers with defined block size and crystallinity are described in this invention. These biodegradable and bioerodable polyesters and copolyesters with controlled molecular weight, dispersity and crystallinity have applications in medical, drug, cosmetic and food industries.
