以聚乙二醇(PEG)为相转移催化剂(PTC),在固-液相转移条件下,制得Azone,实验结果表明:PTC以PEG-400为好,当反应温度为100～110℃时,反应时间短(10h),产率较高达71.3～72.8％,操作简便和成本较低等优点。
Azone was prepared under the condition of solid-liquid phase transfer with polyethylene glycol (PEG) as phase-transfer catalyst (PTC). The results showed that PTC was better than PEG-400. When the reaction temperature was 100-110 ℃ , The reaction time is short (10h), the yield is as high as 71.3 ~ 72.8%, easy to operate and low cost.
