Abstract:
1. A process for making an epoxy resin comprising the steps of: (a) preparing an aryl allyl ether of a phenol or mixture of phenols by reacting (i) a phenol or a mixture of phenols with (ii) an allylation agent; (b) converting an aryl allyl ether of a phenol or mixture of phenols to an α-dihydroxy derivative of a phenol or mixture of phenols (i) in the presence of an oxidant or (ii) in the presence of an oxidant and a catalyst; (c) reacting the α-dihydroxy derivative prepared in step (b) with (i) a hydrogen halide and (ii) a carboxylic acid or carboxylic acid ester to form a phenolic-based α-halohydrin intermediate; and (d) converting the phenolic-based α-halohydrin intermediate prepared in step (c) to an aryl glycidyl ether of a phenol or mixture of phenols as an epoxy compound or resin.
