What is Hydroxypropyl acrylate?

Plain description, key identifiers and synonyms

Hydroxypropyl acrylate appears as a clear colorless liquid. Toxic by inhalation and skin absorption. Corrosive to tissue. May polymerize exothermically if heated or contaminated. If the polymerization takes place inside a container, the container may rupture violently. Vapors heavier than air. Used to make plastics.

Uses and applications

What the substance is used for, by industry and function

Comonomer in adhesives, elastomers, inks, and oil additives, viscosity reducer.

Hydroxypropyl acrylate is mainly used either as a co-monomer in the manufacture of polymers or as a chemical reactant in the manufacture of chemical intermediates.

For the manufacture of hydrogel contact lenses. (3-Hydroxypropyl acrylate).

Indirect Additives used in Food Contact Substances: HYDROXYPROPYL ACRYLATE.

Hydroxypropyl acrylates, usually as isomer mixtures, are used in the industrial production of acrylate polymers for lacquers and artificial resins, and as a co-monomer in adhesives, elastomers, inks, and oil additives and as a viscosity reducer.

Industrial uses: Monomers.

Consumer uses: Binder.

How it is made

Reaction of acrylic acid and propylene oxide, catalyzed by a base

Acrylate esters can be made by reacting a vinyl halide with carbon monoxide and an organic halide in the presence of a Group VIII catalyst. Also developed is a process that yields acrylate esters after the generation of 2-halo-1-alkenes from hydrocarbon streams. Both processes were developed by Dow Chemical Co.

In ... propylene oxidation process acrolein is first formed by the catalytic oxidation of propylene vapor at high temp in the presence of steam. The acrolein is then oxidized to acrylic acid ... The acrylic acid is esterified with alcohol to the ... acrylic ester in a separate process. (Acrylic ester monomers)
