摘要
用热熔融松香直接进行酯化反应,采用导热油作为传热介质,可大大缩短反应时间,所得产品色泽浅。在生产过程中证实,普通松香有“热漂白”的作用。
The thermotropic rosin was used to directly conduct the esterification and the reaction time could be largely shortened through adopting the heat conducting oil as the heat transferring medium.Therefore the colour and lustre of the products were light.It was affirmed in the Productive course that the common rosin possessed the action of “thermal bleach”.
