精对苯二甲酸(PTA)是重要的大宗有机化工原料之一,其主要用途是生产聚酯纤维(涤纶)、聚酯薄膜和聚酯瓶。新世纪以来,随着下游聚酯涤纶产业的快速发展,我国PTA产业逐渐进入快速成长时期,2005年国内PTA产能为640.5万吨/年,到2012年PTA总产能达到3008.5万吨/年,2005～2012年年均
Fine terephthalic acid (PTA) is one of the important bulk organic chemical raw materials, and its main use is the production of polyester (polyester), polyester film and polyester bottles. Since the new century, with the rapid development of downstream polyester polyester industry, China’s PTA industry has gradually entered a period of rapid growth. In 2005, domestic PTA capacity was 6,405,000 tons / year, total PTA capacity reached 30,085,000 tons / year in 2005, and 2005 ~ 2012 annual average
