摘　　要：在模拟蓄冷空调的实验系统中研究了一元醇类添加物对氟利昂R12形成水合物过程的影响 ,结果表明添加异戊醇能形成较稳定的水合物 .同时用量子化学的CNDO/ 2理论方法分析了醇类添加物的影响原因 。The influence of the alcohol additives on the forming of hydrates of Freon R12 has been studied in an simulative cool_storage air_conditioning experimental system. The stable gas hydrate with the iso_pentanol additive has been showed in the experiments. The quantum chemical CNDO/2 method can has been used to study the influence of the alcohol additives on the forming of the hydrates, and the theoretical results can well explain some experimental phenomena.
