Properties and stability
Colorless transparent liquid. It has a sweet and pleasant fruit wine, plum-like aroma. Soluble in most organic solvents. Insoluble in oils. It has good compatibility with most cellulose, polyvinyl chloride, polyvinyl acetate resin and chlorinated rubber. Solubility in water (25℃) 6.5g/100cm3.
Storage method
This product should be sealed and stored in a cool, dry place.
Synthesis method
It is produced by direct esterification of citric acid and ethanol, and then through refining processes such as neutralization, water washing, and dealcoholization.
Purpose
Due to its strong solubility, good oil resistance and light resistance, it is mainly used as a plasticizer for thermoplastic resins such as cellulose and vinyl. Also used in the paint industry. It can be used as berry-type food flavor, and the final food content can reach 200mg/kg. Also used as a solvent for nitrocellulose.
