Abstract
A process for manufacturing an α-halohydrin intermediate and an epoxy resin prepared therefrom including epoxidizing an α-halohydrin intermediate produced from an in situ halide substitution-deesterification of an α-hydroxy ester derivative which has been obtained by the coupling reaction of a phenol or a mixture of phenols and a glycidyl ester optionally in the presence of a catalyst.
Claims57
An epoxy resin product made by epoxidizing an α-halohydrin intermediate of at least one or more phenols formed by reacting (a) an α-hydroxy ester derivative of at least one or more phenols with (b) a hydrogen halide.
An epoxy resin product made by epoxidizing an α-halohydrin intermediate formed by:
- (a) preparing an α-hydroxy ester derivative of at least one or more phenols by reacting at least one or more phenols with a glycidyl ester or substituted glycidyl ester;
- and
- (b) reacting the α-hydroxy ester derivative of at least one or more phenols with a hydrogen halide to form the α-halohydrin intermediate.
An epoxy resin product made by the steps of:
- (a) preparing an α-hydroxy ester derivative of at least one or more phenols by reacting at least one or more phenols with a glycidyl ester of substituted glycidyl ester;
- (b) preparing an α-halohydrin intermediate by reacting the α-hydroxy ester derivative of Step (a) with a hydrogen halide;
- and
- (c) epoxidizing the α-halohydrin intermediate of Step (b).
An epoxy resin product made by the steps of:
- (a) providing a glycidyl ester or substituted glycidyl ester of a carboxylic acid;
- (b) preparing an α-hydroxy ester derivative of at least one or more phenols by reacting at least one or more phenols with the glycidyl ester or a substituted glycidyl ester of Step (a);
- (c) preparing an α-halohydrin intermediate by reacting the α-hydroxy ester derivative of Step (b) with a hydrogen halide;
- and
- (d) epoxidizing the α-halohydrin intermediate of Step (c).
An epoxy resin product made by the steps of:
- (a) providing an allyl ester or a substituted allyl ester of a carboxylic acid;
- (b) preparing a glycidyl ester or a substituted glycidyl ester by epoxidizing the allyl ester or a substituted allyl ester of Step (a) with an oxidant;
- (c) preparing an α-hydroxy ester derivative of at least one or more phenols by reacting at least one or more phenols with the glycidyl ester or a substituted glycidyl ester of Step (b);
- (d) preparing an α-halohydrin intermediate by reacting the α-hydroxy ester derivative of Step (c) with a hydrogen halide;
- and
- (e) epoxidizing the α-halohydrin intermediate of Step (d) to form an epoxy resin product.
An epoxy resin product made by the steps of:
- (a) providing allyl acetate;
- (b) preparing glycidyl acetate by epoxidizing the allyl acetate of Step (a) with an oxidant;
- (c) preparing a bis(α-hydroxy acetoxy) derivative of bisphenol A by reacting bisphenol A with the glycidyl acetate of Step (b);
- (d) preparing a bis(α-chlorohydrin) intermediate of bisphenol A by reacting the bis(α-hydroxy acetoxy) derivative of bisphenol A of Step (c) with hydrogen chloride;
- and
- (e) epoxidizing the bis(α-chlorohydrin) intermediate of bisphenol A of Step (d) to form an epoxy resin product.
