摘　　要：综述了目前取代剧毒原料光气进行有机合成的十二种有价值的绿色化学方法 ,以典型合成路线为基础 ,介绍了其优缺点 ,发展现状及存在的问题 ,得出结论 ,碳酸二甲酯的方法是当前最为廉价且已有大规模生产的方法 ,三光气、碳酸乙烯酯取代光气也取得了一定成绩 ,而一氧化碳羰基化有很好前景 。In this paper,twelve environmen Tally benign methods which can substitute the toxic gas phosgene to synthesize organic substances are summarized,the advantages and disadvantages,development and the existing questions are introduced.Conclusion:Using dimethel carbonate(DMC) to substitute phosgene is the lowest-cost method that has already had cosmically production.The studying of ethylene carbonatel and triphosgene have also obtained achievements in degree.The method of carbon monoxide has a promising future,but should study in the catalytic systems deeply.
