Infra-red and ultra-violet spectra show that 3,4-dimethyl-5-hydroxyisoxazole exists in aqueous and chloroform solution, and in the solid phase in the OH form; and that 3-phenyl-, 4-bromo-3-phenyl-, and 4-methyl-3-phenyl-isoxazol-5-ones exist as mixtures of the CH and NH forms in solution, the proportion of the NH form increasing with the polarity of the solvent. The basicities of isoxazole and some
红外光谱和紫外光谱表明,3,4-二甲基-5-羟基异恶唑存在于水溶液和氯仿溶液中,并且以OH形式存在于固相中。且溶液中CH和NH的混合物形式存在3-苯基-,4-溴-3-苯基-和4-甲基-3-苯基-异恶唑-5-酮,NH的比例随溶剂的极性。记录了异恶唑及其某些衍生物的碱性。异恶唑-5-酮是与羧酸相当强度的酸。
