摘要
以各种醇为溶剂测定了丙酮和环己酮的羰基紫外吸收能量△E,讨论了△E与醇分子结构的关系。
Using a series of alcohols as solvents, the ultraviolet absorption energy ( AE) values of carbonyl (C = 0) for acetone and cyclohexanone were determined.The relations between those AE values and the molecular structure of solvent alcohols were discussed. The obtained results showed that there is a good linear relation between the AE value and the alkyl polarizability effect index PEI value of alcohol molecule, that is AE= a + bPEI.
