摘要
以可再生的蓖麻油为主要原料,H3PO4作为催化剂,30%H2O2作为氧源,在无溶剂条件下合成环氧蓖麻油。通过正交实验的方法对蓖麻油环氧化反应进行了研究和探讨,得出最佳反应条件为:n(H2O2)∶n(蓖麻油双键)=1.4∶1,n(甲酸)∶n(蓖麻油双键)=0.5∶1,催化剂H3PO4质量分数为蓖麻油的0.3%,反应时间6 h,所得产物环氧值为3.23%,并采用红外光谱、碘值分析和薄层色谱对环氧化产品进行了分析表征。
Using renewable castor oll as the main raw material, H3 PO4 as catalyst ancl H2 O2 （30%, mass fraction） as oxidation agent, epoxidized castor oil was prepared without solvent. The synthesis conditions were studied using orthogonal experiment. The optimized reaction conditions were as follows： n（ H2O2 ）： n（double bonds of castor oil） = 1.4 ： 1, n （ formic acid） ： n （ double bonds of castor oil） = 0. 5 ： 1, the amount of catalyst H3 PO4 was 0. 3% and reaction time was 6 h. Under these optimized conditons, the epoxy value of the final product was 3.23%. FT-IR, iodine value analysis and TLC were employed to characterize the product.
