摘要: 以马来酸酐为原料先进行CnH2n+1OH(n=2-9)醇解合成马来酸单酯,然后催化转型生成富马酸单酯,再与甲酸酯化合成了一系列非对称富马酸酯类,产率85%以上。抗菌试验表明,非对称富马酸酯类可使微生物的生长适应期(to)延长2-8倍,半对数生长期(t0.5)缩短1/3-2/3,相对生长量降低75%以上,生长势外(t0.5/t0)为对照的1/28-1/6,并可显著地诱导和促进微生物菌群的自溶作用。

Abstract:  Metbyln-alkyl ethyl, propyl, butyi, amyl, nonyl, fumarates were preparaed, the yields were over 85% These diesters could effectively prolong adaptive phuse(t0) of bacteria from deteriorate ham sauage for 2-8 times, sharten the half logdrithmic growth phase(t0.5) to 1/3-2/3, t0.5/t0 values were only 1/28-1/6 of the control. Methyln-alkyl fumarates significanily inhibited the growth and induced the autolysis of bacteria.
