摘要
本文根据酒精中的主要有害物质──甲醇、杂醇油和醛的物理和化学性质，系统地研究了物理和化学的去杂方法，确定了酒精去杂的新工艺：待处理酒精→（１号树脂柱）４号树脂柱→（１号分子筛柱）２号分子筛柱→简单蒸馏或过滤→优质酒精。通过该工艺流程，对酒精中的甲醇、杂醇油和醛的平均去除率分别为９３．６％、７７．８％和８０．８％，故该工艺能有效地去除酒精中的杂质。
he physical and chemical methods for eliminating impurites from alcohol were systematically studied, therefore,the process for eliminating impurities in alcohol was described as follow: crude alcohol→ (No. 1 ion exchange resin pillar)No. 4 ion exchange resin pillar→ (No. 1 molecular sieve pillar)No. 2 molecular sieve pillar→simple distillation or filtration→high grade alcohol. The resting results showed that over 85%, 92%. 77%. and 80% of water. methanol. fusel oil and aldehydes were respectively eliminated by this process. So impurities in alcohol could be cleared up by combining of No. 1and No. 2 molecular sieves, No. 1 and No. 4 ion exchange resins.
