Alkylation of 2,6-di-tert-alkylphenols with alkanediols |
摘要 |
There is a process disclosed for alkylating the nucleus of a phenol, said process comprising reacting an alpha , omega alkanediol containing from 3 to 8 carbon atoms with a phenol having an unsubstituted nuclear position para to the phenolic hydroxyl group; said phenol being selected from the group of alkylated phenols having tertiary alkyl groups of 4 to 8 carbon atoms in both positions ortho to the phenolic hydroxyl group, in the presence of an alkali metal hydroxide or alkoxide or alkali metal at a temperature from 200 DEG to 300 DEG C. while continuously removing the water by-product as it forms and obtaining as a product said phenol having a primary hydroxy terminated alkyl group of 3 to 8 carbon atoms in said para position.
