用玉米淀粉制备交联淀粉的工艺

Preparation of Crosslinked Starch With Corn Starch

以玉米淀粉为原料,以柠檬酸和乙酸酐为交联剂制取交联淀粉,通过反复试验研究了不同混合酸的用量、不同混合酸比例、不同反应时间、不同反应温度条件对交联淀粉交联效果的影响,最后采用正交试验优化了制备交联淀粉的工艺条件,为制备交联淀粉提出了新工艺。

Based on corn starch as raw material, citric acid and acetic anhydride as cross-linking agent for preparing crosslinked starch, through repeated experiments to study the effect of different mixed acid, mixed acid ratio,reaction time, reaction temperature on different cross-linked starch cross-linkingeffect, the preparation process of cross-linked starch optimization orthogonal test, for the preparation of cross-linked starch presents a new process.
