Solvent-free process for preparing liquid epoxy resins |
| abstract |
Liquid epoxy resins are produced in solvent-free process by (1) coupling a dihydric phenol with an excess of an epihalohydrin in the presence of a suitable catalyst, (2) removing the excess epihalohydrin, (3) dehydrohalogenating the resultant solvent-free halohydrin intermediate at an elevated temperature and (4) removing inorganic reaction product materials by water washing the resultant solvent-free liquid epoxy resin at elevated temperature to obtain a liquid epoxy resin. |
