| 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. |
