碳酸二苯酯是合成聚碳酸酯的重要原料,具有广泛的用途和应用前景。本文综述了不同醇类的尿素醇解反应以及不同碳酸二烷酯与苯酚的酯交换反应,结合以醇为循环剂由尿素法合成碳酸二苯酯的研究现状,对该过程进行分析探讨。分析表明,长碳链脂肪醇是适合该反应的循环剂,并展望了其今后的发展方向。 Diphenyl carbonate is an important raw material for the synthesis of polycarbonate, with a wide range of uses and prospects. In this paper, the alcoholysis of different alcohols and the transesterification of different dialkyl carbonates with phenol were reviewed. The current research status of the synthesis of diphenyl carbonate from urea by alcohol as the recycling agent was reviewed. The analysis shows that the long chain fatty alcohol is suitable for the reaction of the cycle agent, and its future development prospects.
