摘 要:以D,L-乳酸(2)为原料,丙三醇(1)固定羧基制得低聚乳酸(3),其结构经MS表征。最佳反应条件为:2141.5 mol,n(2):n(1)=30,于(150~160)℃/(0.5~3.0)kPa条件下反应20 h,收率93.0%。首次将3或其复配物4[m(3):m(碳酸钙):m(环氧大豆油)=100:15:3]应用于家禽脱毛,结果表明,3和4的脱毛效果良好。Low poly(lactic acid)(3) in yield of 93.0% was prepared from D,L-lactic acid(2) by new method using glycerol(1) to control the molecular weight and distributon of molecular weight.The structure was confirmed by MS.The optimum reaction conditions at(150~160 ℃/(0.5~3.0) kPa for 20 h were as follows:2 was 141.5 mol,n(2):n(1) was 30.Depilations performance of 3 and its mixture 4[m(3):m(CaCO3):m(epoxidized soybean oil)=100:15:3] on poultry were first investigated.The results showed that 3 and 4 exhibited good depilations performance.
