摘　　要：我国环己酮生产和需求增长较快,2011—2015年环己酮产量和表观消费量年均增长率分别达到17.8%和18.1%,2015年我国环己酮生产能力和产量分别为3 650 kt/a和2 841 kt,其中88%的产量用于己内酰胺和己二酸的生产,溶剂、防老剂、交联剂等其他产品约占环己酮总消费量的12%。己内酰胺是我国环己酮的最大下游产品,2015年我国己内酰胺生产能力为2 350 kt/a,产量为1 782 kt,产能过剩风险加剧;己二酸是环己酮第二大消费领域,2015年我国己二酸生产能力为1 970 kt/a,产量为1 138 kt,产能过剩较为严重。国内环己酮已经呈现产能过剩态势,建议未来应增加出口,拓展国外市场;加大环保清洁工艺的开发,降低生产成本;协调上下游发展,开发其他下游市场。The production and demand of cyclohexanone has been growing rapidly in China,and the production and apparent consumption of cyclohexanone during 2011 to 2015 reached 17. 8% and 18. 1% respectively. In2015,the production capacity and output of cyclohexanone in China reached 3 650 kt / a and 2 841 kt respectively,of which 88% of output for the production of caprolactam and adipic acid,and about 12% for production of solvents, antioxidants, crosslinking agents and other products. Caprolactam is the major downstream product of cyclohexanone. In 2015,the production capacity and output of caprolactam in China reached 2 350 kt / a and 782 kt respectively,with high risk of overcapacity. Adipic acid is the second largest consumer of cyclohexanone. In 2015,the production capacity and output of adipic acid in China reached1 970 kt / a and 1 138 kt respectively,with serious overcapacity. As overcapacity trend of cyclohexanone in domestic market has presented,proposals were raised for increasing exports and expanding overseas markets,increasing the development of environmentally friendly cleaning process, reducing production costs,coordinating development of upstream and downstream industries,and developing other downstream markets.
