Abstract

Butirrati di propilenglicol monometiletere e loro isomeri sono ottenuti per esterificazione di propilenglicol monometiletere o suo isomero con acido isobutirrico o n-butirrico ad elevata temperatura, oltre 80°C, in presenza di catalizzatore acido e agente azeotropico. Questi composti vengono rettificati per rimuovere residuo acido e umidità onde ottenere il prodotto desiderabile di elevata purezza.
