摘　　要：叙述了 3 环己烯甲醛在贮存中由于环境影响 ,使其组成发生变化的机理和预防措施。结果表明 3 环己烯甲醛在空气中自动氧化成酸 ,且在酸性介质中水解成 2 羟基己二醛 ,而加入冰醋酸可抑制自动氧化反应和水解反应 。The autoxidation and some other chemical reactions of cyclohexenyl formaldehyde in store could take place and its composition could change.In this paper,the mechanism of autoxidative reaction and its precaution were investigated and showed that the cyclohexenyl formaldehyde was autoxidized to form cyclohexenyl formic acid and hydrolyzed to form 2-hydoxy hexanedial.However,the two reactions could be inhibited by addition of glacial acetic acid.Therefore the precaution method was set up accordingly.
