摘要
通过响应面分析(Response surface analysis,RSA)软件,采用boxbehnken中心组合设计方法对辛烯基琥珀酸淀粉酯(SSOS)的制备工艺条件进行优化,得到制备辛烯基琥珀酸淀粉酯的最佳工艺条件为:反应温度为34℃,时间1.5h,pH值为8.7,辛烯基琥珀酸酐添加量为淀粉干基的3%,反应取代度(DS)可达0.0144。
Octenyl succinic anhydride (OSA) modified waxy com starch was prepared in aqueous slurry systems with the Box-Behnken in the RSA software. According to the central composite test design principles, the method of response surface method (RSM) with 4 factors and 3 levels was adopted. Response surface and contour are finally graphed with the degree of substitution (DS) as the response value. The suitable parameters were as follows: reaction temperature 34℃, reaction period 1.5h, pH of reaction system 8.7, amount of OSA 3% (in proportion to dry starch). The degree of substitution was 0.0144.
