With the deepening of hydrophobic modification,the dispensability of modified starch in organic solvent liquid paraffin is markedly enhanced. The particle shape changes from rarefaction to cluster grape ball agglomeration state. The long chain group of methoxyl silane coupling agents KH570 is linked with the anhydrous glucose units of the cross-linked starch.

随着疏水化改性程度的加深，改性淀粉在液体石蜡有机介质中的分散性明显增强；颗粒形态由疏松态向串状葡萄球团聚态转变；在交联淀粉脱水葡萄糖单元羟基上引入了甲氧基硅烷偶联剂KH570的长链基团。

The results indicate that improving temperature to reflux, using low polarity solvent as dispersion medium and proper molar ratio of tetrabutyl titanate to stearic acid can bring out good modification. The function of tetrabutyl titanate is to react with the surface hydroxyl groups and adsorbed H2O on the powder particles to produce new binding sites such as M—O—Ti—OC4H9and M—O—Ti—OH, which can easily react with the carboxylic acid. As temperature increases from room temperature to reflux temperature, the reactions between RCOO- and Ti change from coordinate bonds to covalent bonds, which makes the carbon chains of stearic acids more strongly bound with the powder particles surface.

研究结果表明，提高处理温度、适当增加复合改性剂中硬脂酸的量并选用极性弱的有机溶剂可达到比较理想的改性效果；钛酸四丁酯的作用是与粉体粒子表面的羟基以及吸附水反应产生偶联点，如M—O—Ti—OH，这些偶联点易于与羧酸反应；在低温时RCOO-与偶联点的Ti之间以配合物的形式发生作用，在回流温度下处理时，主要发生酯化反应，使硬脂酸更牢固地嫁接到粉体粒子表面，改性效果更好。
