Propylene glycol methyl ether acetate (also known as PGMEA, 1-methoxy-2-propanol acetate) is a P-type glycol ether. It is a non-polluting solvent with multi-functional groups. Its molecular formula is C6H12O3. It is a colorless liquid with a mild odor. It has an excellent solvent activity and slow evaporation rate. Moreover, it is readily biodegradable.
Traditionally, PGMEA is produced through the esteriï¬cation reaction of acetic acid and propylene glycol methyl ether (PM) in the presence of chosen acid catalyst. In this conversion, there are techniques to improve and intensify the reaction: distillation and chromatography. Because the finished product has acidic impurities, usually to achieve the desired properties, PGMEA has to go through thorough postprocessing to be purified.
Propylene glycol methyl ether acetate is used in the electronics industry as the cleaning agent used to clear the liquid crystal displays.
In the textile industry, PGMEA can be found as a solvent for textile dyes. It is also used as a lubricant. The chemical is also used as a solvent for various printing inks and paints.
