一、我国生产与消费概况我国丁二烯的生产是在70年代随着石油化工的发展而逐步发展起来的。改革开放以后,产量增长较快。1990年我国丁二烯产量达到25.77万吨,1995年上升到33.62万吨。1997年增长到49.68万吨,为历史最高纪录,比1990年增长93%,7年间年均增长率为9.8%。其中,“八五”计划期间年均增长率为5.5%;“九五”计划期间的前2年年均增长率高达21.6%。1998年丁二烯产量46.70万吨。
I. Overview of China’s production and consumption The production of butadiene in China was gradually developed in the 1970s with the development of petrochemical industry. After the reform and opening up, the output has grown faster. The output of butadiene in China reached 257,700 tons in 1990 and rose to 336,200 tons in 1995. In 1997, it increased to 49.68 million tons, which was the highest record in history. It was 93% higher than that in 1990 and the average annual growth rate was 9.8% in 7 years. Among them, the average annual growth rate during the “Eighth Five-Year Plan” period was 5.5%; during the “Ninth Five-Year Plan” period, the average annual growth rate during the first two years was as high as 21.6%. In 1998, the production of butadiene was 467,700 tons.
