Formation regulation of various rosin esters and intensification mechanism using pressurized CO 2
The esterification of rosin with pentaerythritol (PE) was studied, using pressurized CO 2 as an intensified additive to high-temperature water (HTW), which formed the various esters with different soften points to meet industrial applications. A multiple linear regression model was established to de...
