摘要
全球双酚A生产能力已超过270万t/a,其中前5家生产商(GE、Shell、Bayer、Dow、三井化学)的生产能力占全球总能力的75％以上。由于技术上的原因,2000年国内双酚A生产企业能保持正常开工的只有无锡石油化工总厂一家,年产仅1.1万t左右。2000年我国双酚A净进口量为6.57万t,如加上环氧树脂、聚碳酸酯的进口量,折成双酚A的当年净进口量可达30.9万t。我国生产的双酚A主要是用于环氧树脂的生产,由于聚碳酸酯生产技术落后,消耗双酚A的量很少,另有一小部分双酚A用于阻燃剂四溴双酚A、聚砜和不饱和聚酯树脂等的生产。
The world capacity of BPA has exceeded 2. 7 million t/a. The combined capacity of the top five producers including GE, Shell, Bayer, Dow, Mitsui Chemical accounts for over 75% of the worlds total output. In 2000, among the domestic BPA producers, only Wuxi Petrochemical General Plant kept normal operation due to technical problems with the domestic BPA output being 11, 000 t/a. The net imports of BPA were 65,700 t in that year. If the imports of epoxy resin and polycarbonate were added and converted into BPA, the total imports were 309,000t. BPA is mainly used in the production of epoxy resin in China, and a small part is used in the production of polycarbonate, tetrabromobisphenol A, polysulfone, unsaturated polyester resin and etc.
