Abstract
1425773 Epoxy resins DOW CHEMICAL CO 3 Sept 1973 41388/73 Heading C3B A process for preparing solid epoxy resins by interfacial condensation comprises reacting an aromatic polyhydroxyl-containing compound with a halohydrin in the presence of an alkaline dehydrohalogenating agent, e.g. NaOH or Na 2 CO 3 , for a reaction of from 2-10 minutes and at a temperatore of from 75-160‹ C. wherein water is used as the sole reaction medium in an amount of from 3-20 p.b.w. of water per each p.b.w. of the combined weights of the reactants. Suitable polyhydroxyl compounds are resorcinol, catechol, hydroquinone; or a compound of the formula wherein A is a C 1 -C 4 alkylene or alkylidene group, -S-, -SS-, -O-, -SO-, -SO 2 - or -CO- and R and R 1 are hydrogen, chlorine or bromine; or a compound of the formula where R is hydrogen, a C 1 -C 4 alkyl group, X is hydrogen, Cl, Br or a C 1 -C 4 alkyl group and n has an average value of 0À01-0À5. Suitable halohydrin compounds are glycerine dichloro- (or dibromo-)hydrin, or an epihalohydrin. The reaction is preferably carried out while mixing with a high shear mixer. In the examples epoxy resins are prepared from p,p<SP>1</SP>-isopylidene diphenol, epichlorohydrin in the presence of sodium hydroxide and water. Uses.-Coatings.
