Vinyl propionate is a chemical compound from the group of propionic acid esters .

Extraction and presentation

Vinyl propionate can be obtained from ethyne and propionic acid in the gas phase with zinc propionate on activated carbon as a catalyst .

properties

Vinyl propionate is a highly flammable, volatile, colorless liquid. It is sparingly soluble in water and has unlimited solubility in ethanol , all common solvents and vegetable oils. It tends to polymerize and is therefore industrially mixed with inhibitors such as 4-methoxyphenol in the range of about 100 ppm.

use

Vinyl propionate is used as a starting material for the production of homopolymers and copolymers with monomers such as (meth) acrylic compounds, vinyl chloride and other vinyl esters .

safety instructions

The vapors of vinyl propionate can form an explosive mixture with air ( flash point 1 ° C, ignition temperature 385 ° C). Like the structurally related vinyl acetate, vinyl propionate is rapidly hydrolytically split by esterases to give the respective acid and vinyl alcohol , which is then further metabolized to acetaldehyde . Acetaldehyde and vinyl acetate are classified in category 3 of the carcinogenic substances.
