    • 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).
    • 一种制备脂族或环脂族环氧树脂的方法,包括以下步骤:(I)使(a)含脂肪族或脂环族羟基的材料,(b)表卤代醇,(c)碱性作用物质,(d) 非路易斯酸催化剂和(e)任选的形成环氧树脂组合物的溶剂; (II)将步骤(I)中制备的环氧树脂组合物进行分离处理以除去(A)“轻”成分,例如环氧化反应中使用的溶剂(如果有的话)未反应的表卤代醇和共同产物 如二(环氧丙基)醚; (B)未反应的脂肪族或脂环族羟基的物质,如果有的话; (C)部分环氧化脂族或脂环族羟基的材料,例如MGE; (D)完全环氧化的脂族或脂环族羟基的材料,例如DGE,使得(E)脂族或脂环族多官能环氧树脂产物含有不超过50重量%的所述完全环氧化的脂族或脂环族羟基 (D); 和(III)将来自步骤(II)的分离的部分环氧化脂族或脂环族羟基的材料(C)和部分环氧化的含脂肪族或含脂环族羟基的材料(C)的混合物与完全环氧化的脂族或脂环族羟基化合物(D) 与步骤(I)的新的反应混合物。
