专用化学品、精细化工的重要性已成共识。 从60年代到70年代,国外工业发达国家石油化学工业高速发展,有机化工原料来源几乎全部转向石油、天然气。此后,大宗化工产品逐渐出现过剩。美、日、西欧等工业发达国家关停部分石油化工生产装置。据联合国工业发展组织统计,1980～1985年美、日、西欧等工业发达国家停产乙烯装置的生产能力达700多万t。随后,石油化工发展速度减慢。 其实,这是合乎规律的现象。从总体上讲是石油化工的发展速度趋于合理,即与国民生产总
The importance of specialty chemicals and fine chemicals has become a consensus. From the 1960s to the 1970s, the petrochemical industry developed rapidly in foreign industrial countries, and the sources of organic chemical raw materials almost all turned to oil and natural gas. Since then, there has been a gradual surplus of bulk chemical products. Some industrialized countries such as the United States, Japan and Western Europe have shut down some petrochemical production facilities. According to statistics from the United Nations Industrial Development Organization, the production capacity of ethylene production facilities in industrialized countries in the United States, Japan and Western Europe from 1980 to 1985 exceeded 700 million tons. Subsequently, the pace of petrochemical development slowed. In fact, this is a lawful phenomenon. Generally speaking, the development speed of petrochemical industry tends to be reasonable, that is, with the national production
