The conversion of propylene glycol was mainly affected by the surface acidity of the catalyst. 乙醛和丙二醇(PG)的缩醛化反应表明丙二醇(PG)的转化率主要受催化剂表面弱酸度的影响。
DPMA Di ( propylene glycol ) methyl ether acetate; 二丙二醇(PG)甲醚醋酸酯;
The application of different levels of propylene glycol alginate ( PGA ), pectin and denatured starch as the stabilizer blends in stirred yoghurt was studied in this paper. 研究了海藻酸丙二醇(PG)酯(PGA)、果胶和变性淀粉作为复配稳定剂在搅拌型酸奶中的应用。
