目前,我国能生产染/颜料中间体近500个品种,生产企业已超过1300家。据初步统计,1999年我国染/颜料中间体产量约42万t,其中苯系中间体约34万t、萘系中间体4.13万t、蒽醌系中间体1.3万t、杂环系中间体1200t,当年出口量约有11万t,有60多个出口品种在国际市场上具有一定影响力。本文介绍了近年我国染/颜料中间体新品种、致癌芳香胺代用品的开发情况,生产过程清洁工艺和新技术的开发和使用情况,并就今后发展提出了建议。
At present, China can produce nearly 500 varieties of dye/pigment intermediates, and there are more than 1,300 production companies. According to preliminary statistics, in 1999, the output of dye/pigment intermediates in China was about 420,000 tons, including about 340,000 tons of benzene-based intermediates, 41.000 tons of naphthalene intermediates, 13,000 tons of lanthanide intermediates, and heterocyclic intermediates. At 1200 tons, the export volume was about 110,000 tons, and more than 60 export varieties had a certain influence in the international market. This article introduced the development of the new dye/pigment intermediates, carcinogenic aromatic amine substitutes, the development process and the use of new technologies in the production process, and put forward suggestions for future development.
