以7 苯乙酰氨基 3 E 丙烯基 3 头孢菌素 4 羧酸为原料,在青霉素酰化酶作用下,首先酶法水解得到3 E 丙烯基 3 头孢菌素 4 羧酸,过滤固相酶,滤液调pH分离得到反式APRA固体;在青霉素酰化酶作用下,反式APRA再与对羟基苯甘氨酸乙二醇酯缩合,得到反式头孢丙烯;酶法合成所得的产品与进口反式头孢丙烯对照品一致。

Amino to acetyl phenol, in have technology of two kinds of production domestic and internationally, acetic anhydride craft of the United States, acyl changes temperature to have 75 ℃ only, acyl changes mother liquor not apply mechanically, deputy reaction is little, of production thick tasting is kind of white almost, purificatory craft is very simple, activated carbon dosage only 2~3%, the Kun that its product does not have glow material almost in different third alcohol inferior the sealed impurity of amine impurity and minim, settleclear lightness it may not be a bad idea, the product quality that acetic anhydride craft produces is good, but close rate low, cost is high.

对乙酰氨基酚,在国内外有两种生产工艺,美国的醋酐工艺,酰化温度只有75℃,酰化母液不套用,副反应少,生产的粗品几乎是类白色,精制工艺就非常简单,活性炭用量仅2~3%,其产品在异丙醇中几乎无红光物质的醌亚胺杂质及微量的未知杂质,澄明度也好,醋酐工艺生产的产品质量好,但收率低、成本高。

In order to improve their water solubility, 4"-fatty amido-3"-sodium carboxylate azobenzene-4-sodium sulfonates were synthesized. They are azo compounds with two hydrophilic groups of carboxyl and sulfonyl. They decrease the surface tension in dilute solution slowly, and show some surfactivity, but are not surfactants. The probable reason is their relative strong hydrophile. Furthermore, their colors are not fresh and far from our destination.
