Abstract
1,051,738. Glycidyl polyethers of polyhydric phenols. DEVOE & RAYNOLDS CO. Inc. June 5, 1963 [June 6, 1962], No. 22407/63. Heading C3B. Glycidyl polyethers of polyhydric phenols are prepared by reacting: (A) a complex phenol polyether alcohol of the formula wherein R<SP>1</SP> is the hydrocarbon radical of a dihydric phenol R<SP>1</SP>(OH) 2 and a is 0 or an integer up to 10, and (B) a phenol of the formula R<SP>11</SP>(OH) x wherein R<SP>11</SP> is the aromatic radical and x is an integer from 2 to 10, with (C) a molar excess of epihalohydrin, in the presence of caustic alkali as a dehydrohalogenating agent, and dehydrohalogenating the mixed halohydrin ether formed to produce the glycidyl polyether. The molar ratio of (A) to (B) is from 1 : 10 to 10 : 1 and the molar amount of epihalohydrin is z(m(a + 2) + nx), wherein a and x are as defined above, m is the number of moles of (A), n is the number of moles of (B) and z is a number from 2 to 15. 1 Mole of alkali is used per phenolic hydroxyl group. The glycidyl polyether is freed of salt by washing, or filtering after the removal of excess epihalohydrin and the addition of a solvent. The phenol mixture and the epihalohydrin may be reacted in the presence of any alkaline catalyst or of a quaternary ammonium salt to give the halohydrin ether before dehydrohalogenation with the caustic alkali or the caustic alkali itself may act as the catalyst.
