Propylene Glycol Methyl Ether Acetate CAS#108-65-6
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.
