Abstract

Polyalcohols are made by etherifying phenolformaldehyde novolaks having from 4 to 10 phenolic units per molecule, in the presence of a basic catalyst, with from 0.85 to 1.2 mol. per phenolic hydroxyl of ethylene and/or propylene oxide, under (at least initially) superatmospheric pressure, said alkylene oxide being introduced into the reaction zone at such a rate that the reaction temperature is in the range 120-225 DEG C., the resultant polyalcohols being insoluble in aliphatic, aromatic and terpene hydrocarbons and soluble in one or more aliphatic alcohols, ketones and ethers. Specified solvents are ethanol, acetone, ethyl acetate and dioxane. The resultant polyalcohols may be esterified with drying or semi-drying oil fatty acids. Specified basic catalysts are sodium, potassium and barium hydroxides and tertiary amines. In the examples, novolaks prepared from phenol and formalin in the presence of (1) hydrochloric acid, (2) sulphuric acid, and (3) oxalic acid are reacted with (1) ethylene oxide in the presence of caustic soda and esterified with linseed oil fatty acids (2) propylene oxide (catalyst barium hydroxide) and esterified with drying oil fatty acids (3) ethylene oxide (catalyst caustic soda) and esterified with linseed oil fatty acids. Specification 775,460 is referred to.
