摘　　要：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 synthesis of polycarbonate and possesses wide uses and application prospect. The researeh progress in the alcoholysis reactions between different alcohols and urea, and transesterification between different dialkyl carbonates and phenol was reviewed. According to the comprehensive analysis for the synthesis of diphenyl carbonate from urea and phenol with an alcohol as recycling agent, it was suggested that the long ehain aliphatic alcohols are the good recycling agents for the process. Problems encountered in the reaction process were analyzed and the future development was also prospected.
