ABSTRACT:
A method is disclosed of alkylating substituted hydroxybenzenes, particularly substituted hydroxybenzaldehydes, by reacting the hydroxybenzene compound with a dialkylsulfate in the presence of an alkali metal carbonate, substantially in the absence of a solvent. The alkoxylated product is obtained in yields substantially close to theoretical.
