Wholesale Carbomer 940 - Ethylene Glycol Monoethyl Ether Acetate With 111-15-9 – Unilong

Obtained by the reaction of ethylene glycol monoethyl ether and acetic anhydride. Mix acetic anhydride and concentrated sulfuric acid. After heating to 130°C, slowly add ethylene glycol monoethyl ether dropwise. The reaction temperature is maintained at 130-135°C. The flow was added for 1-2 h, and the reflux temperature was 140 °C. After cooling, neutralize with sodium carbonate to pH=7-8, and then dry with industrial anhydrous potassium carbonate. The desiccant was filtered off for crude fractionation, and the distillate between 150-160°C was collected. Fractionation is carried out again, and the fraction at 155.5-156.5°C is collected as the finished product. It can also be obtained by catalyzing ethylene glycol monoethyl ether and acetic acid with concentrated sulfuric acid and refluxing in benzene.

It is used as a solvent for resin, leather, ink, etc. It is used as a solvent, and is used as a leather adhesive, paint stripper, metal hot-dip anti-corrosion coating, etc. in combination with other compounds. It can be used as a solvent for metal and furniture spray paint, as a solvent for brush paint, as a solvent for protective coatings, dyes, resins, leather, inks, and in the formulation of hard surface cleaning agents such as metal and glass. as chemical reagents.
