2011年底,我国酯化级丙烯酸(CAA)总产能达到149.8万吨/年,占当年世界CAA总产能的28.2%,是近年全球丙烯酸生产发展最快的地区。预计到2015年国内丙烯酸产能有望突破240万吨/年,成为世界上最大的丙烯酸生产国。由于原料及生产技术的限制,我国丙烯酸及酯行业与国际水平还有差距,笔者建议企业走“产学研”一体化道路,充分利用国内产能过剩的原料,打破技术壁垒,扩大下游产品的应用,实现丙烯酸生产工艺的国产化,推动我国丙烯酸及酯行业的可持续发展。
At the end of 2011, the total capacity of esterification grade acrylic acid (CAA) in China reached 1,498,000 tons / year, accounting for 28.2% of the world’s CAA total production capacity in that year, making it the fastest-growing acrylic acid production in the world in recent years. It is estimated that by 2015, domestic acrylic acid production capacity is expected to exceed 2.4 million tons / year and become the largest acrylic acid producing country in the world. Due to the limitations of raw materials and production technology, there is still a gap between the acrylic acid and ester industry in China and the international level. The author suggests that enterprises should follow the road of integration of production, study and research so as to make full use of the raw materials with excess domestic production capacity, break down technical barriers and expand the downstream products Application, to achieve localization of acrylic acid production process, and promote the sustainable development of acrylic acid and ester industry in China.
