The invention belongs to the technical field of preparation of clean-flavor coatings, and in particular relates to a preparation process of a clean-taste film-forming auxiliary. The present invention utilizes alcohols to react with residual isobutyric acid in the preparation of dodecyl or hexadecyl alcohol ester to generate isobutyrate, thereby eliminating the odor in the film-forming aid; the obtained isobutyrate can be used as a film-forming aid active ingredient of the agent. The added amount of alcohol substances used is greater than the amount of isobutyric acid produced in the preparation process of dodecyl or hexadecyl alcohol ester, from promoting the esterification reaction between isobutyric acid and alcohol substances and inhibiting the production of dodecyl/hexadecyl alcohol ester. Hydrolysis, and the excess alcohol can be used as a quick-drying component and an antifreeze component of the coalescent, without affecting the performance of the coalescent. |
