Abstract

Polyglycol ethers of polyhydric alcohols having at least 3 hydroxyl groups are formed by reacting at least 20 mols. of alkylene oxide with each hydroxyl group. Polyhydric alcohols mentioned are trimethylol propane, trimethylol ethane, hexanetriol, pentaerythritol, nitrotrimethylolmethane, and mixtures thereof. Alkylene oxides mentioned are ethylene oxide, propylene oxide and epichlorhydrin. Reaction is preferably effected at elevated temperature, e.g. 120-190 DEG C., and in the presence of sodium alcoholate-especially the one obtained from the polyhydric alcohol used. The reaction may be performed in stages or a low molecular weight addition product of the polyhydric alcohol and the alkylene oxide may be used as starting material. Products are wax-like solids soluble in water, methanol, acetone, benzene, or chloroform. In the examples products are formed from (1) trimethylol propane and 96 mols. of ethylene oxide; (2) trimethylol propane and 135 mols. of ethylene oxide; (3) trimethylol propane and 600 mols. of ethylene oxide; (4) 1,3,5-hexanetriol and 105.2 mols. of ethylene oxide; and (5) trimethylol propane, pentaerythritol and ethylene oxide.
