Abstract

The invention discloses a preparation method of sucrose ester of rosin acid and relates to the technical field of deep processing of rosin. The method comprises steps as follows: alcohol, rosin and sucrose are sequentially added to a swirling cavitation device and uniformly mixed, and then an esterification reaction catalyst is added; the swirling cavitation device is started, the reaction temperature is controlled to be 130-145 DEG C, and reaction is performed for 1-1.5 h; alkali liquor is added to regulate the pH value of a solution to be neutral, the temperature is increased to 150-180 DEG C, and the solution is subjected to heat-preserving distillation for 0.8-1.2 h. According to the preparation method of sucrose ester of rosin acid, the raw material transformation rate is high, few side reactions are produced, the product purity is higher, and the reaction time is short.

Description

technical field [0001] The invention relates to the technical field of rosin deep processing, in particular to a preparation method of rosin acid sucrose ester. Background technique [0002] Rosin is a renewable natural resin widely used in coatings, adhesives, inks, papermaking, soap, metal processing, synthetic rubber, building materials, food, polymers, fine chemicals and other industries. However, due to the instability of rosin itself, its performance and application fields are limited. Therefore, esterification modification of rosin is one of the important ways. [0003] Rosin acid sucrose ester is a kind of surfactant with good biodegradability, which can be used as emulsifier, dispersant and viscosity regulator of food, etc. It is mainly prepared from rosin and sucrose as the main raw materials. However, the current preparation method of sucrose rosin acid ester generally requires a long time of reflux, which takes a long time. Therefore, it is necessary to find a ...
