| titleOfInvention | Process for preparing epoxy resins |
| abstract | A process for preparing an aliphatic or cycloaliphatic epoxy resin including the steps of: (I) reacting a mixture of (a) an aliphatic or cycloaliphatic hydroxyl containing material, (b) an epihalohydrin, (c) a basic acting substance, (d) a non-Lewis acid catalyst, and (e) optionally, a solvent, forming an epoxy resin composition; (II) subjecting the epoxy resin composition produced in step (I) to a separation process to remove (A) “light” components such as, for example, solvent used in the epoxidation reaction, if any, unreacted epihalohydrin, and co-products such as di(epoxypropyl)ether; (B) unreacted aliphatic or cycloaliphatic hydroxyl containing material, if any; (C) partially epoxidized aliphatic or cycloaliphatic hydroxyl containing material, such as, for example, MGE; (D) fully epoxidized aliphatic or cycloaliphatic hydroxyl containing material, such as, for example, DGE, such that the (E) aliphatic or cycloaliphatic polyfunctional epoxy resin product remaining contains no more than 50% by weight of said fully epoxidized aliphatic or cycloaliphatic hydroxyl containing material (D); and (III) recycling the isolated partially epoxidized aliphatic or cycloaliphatic hydroxyl containing material (C) and any mixtures of partially epoxidized aliphatic or cycloaliphatic hydroxyl containing material (C) with fully epoxidized aliphatic or cycloaliphatic hydroxyl containing material (D) from step (II) to a new reaction mixture of step (I). |
