我国间苯二甲酸产不足需,2010年产能仅为5.8万吨/年,但表观需求量达16万吨,进口依存度达80%以上。预计2015年,我国间苯二甲酸产能可达12.8万吨/年,届时消费量将增至21.5万吨,进口依存度仍高达40%,国内产业发展前景较好。但是由于国际间苯二甲酸产能已经过剩,我国企业不可避免的将受到国外高质量产品或是新技术的冲击和威胁,因此,国内企业除了尽快提高生产技术水平外,还应积极进行产品新应用领域的开发和研究,以维护我国间苯二甲酸行业的健康发展。
The demand for isophthalic acid in our country is not enough. In 2010, the capacity was only 58,000 tons / year, but the apparent demand reached 160,000 tons and the import dependence reached more than 80%. It is estimated that in 2015, the production capacity of isophthalic acid in our country will reach 128,000 tons / year, by which time the consumption will increase to 215,000 tons and the import dependence will still be as high as 40%. The domestic industry has a good prospect of development. However, due to the international surplus of phthalic acid production capacity, Chinese enterprises will inevitably be the impact of foreign high-quality products or new technologies and threats, therefore, domestic enterprises in addition to improving production technology as soon as possible, but also should actively carry out new product applications The field of development and research in order to maintain the healthy development of the phthalic acid industry in our country.
