1-Methoxy-2-propyl acetate Chemical Properties,Usage,Production

Description

Propylene glycol methyl ether acetate (PGMEA), also known as propylene glycol monomethyl ether acetate, with molecular formula of C6H12O3, is a colorless hygroscopic liquid with special smell. It is a non pollution solvent with multi-functional groups. It is mainly used as the solvent of ink, paint, ink, textile dye and textile oil agent, and also as the cleaning agent in the production of LCD. Flammable, may form explosive vapor / air mixture above 42 ° C. Propylene glycol methyl ether acetate (PGMEA) is an advanced solvent. Its molecule has both ether bond and carbonyl. Carbonyl forms the structure of ester and contains alkyl at the same time. In the same molecule, there are both non-polar and polar parts. The functional groups of these two parts not only restrict and repel each other, but also play their inherent roles. Therefore, it has a certain solubility for non-polar substances and polar substances.
1-Methoxy-2-propyl acetate (PGMEA) is a material contains polar groups and non polar group , has good ability of dissolving and coupling, commonly used in solvent based coatings and screen printing ink. Using dipropylene glycol methyl ether and acetic acid as raw material, under the catalysis of solid acid, via esterification reaction to generated crude product and its high purity PGMEA after distillation.

Chemical Properties

1-Methoxy-2-propyl acetate(Methoxypropyl Acetate) is a clear, slightly hygroscopic liquid with a mild odour. It is freely miscible with most common organic solvents, but has only limited miscibility with water.
By virtue of its ether and ester groups, Methoxypropyl Acetate enters into reactions that are characteristic of ethers and esters and display their solvent power. For instance, it dissolves numerous natural and synthetic resins, waxes, fats and oils.
Since Methoxypropyl Acetate may react with the oxygen in the air to form peroxides, BASF supplies it inhibited with 2.6-di-tert-butyl-para-cresol (butylated hydroxytoluene – BHT).

Uses

1,2-Propanediol monomethyl ether acetate is used as a solvent for paints, inks, lacquers, varnishes, cleaners and coatings. It is also used as a solvent for degreasing circuit boards and in food contact applications. Further, it is used in photoresist formulations in the semiconductor industry.

Application

1-Methoxy-2-propyl acetate is a high-grade industrial solvent with low toxicity and excellent performance. It has strong solubility for polar and non-polar substances. It is suitable for solvents of various polymers of high-grade coatings and inks, including aminomethyl ester, vinyl, polyester, cellulose acetate, alkyd resin, acrylic resin, epoxy resin and nitrocellulose. Among them. Propylene glycol methyl ether propionate is the best solvent in coatings and inks. It is suitable for unsaturated polyester, polyurethane resin, acrylic resin, epoxy resin, etc.

General Description

Propylene glycol monomethyl ether acetate (PGMEA) is a photoresist solvent. Its degradation by microorganisms in different soil types has been investigated. An oral reference dose (RfD) value of PGMEA has been obtained from inhalation studies. The solubility of (5-alkylsulfonyloxyimino-5H-thiophen-2-ylidene)-2-methylphenyl-acetonitriles in PGMEA has been analyzed.

Flammability and Explosibility

Flammable

Safety Profile

Moderately toxic by intraperitoneal route. Slightly toxic by ingestion and skin contact. When heated to decomposition it emits acrid smoke and irritating vapors.
