Ⅰ概述近来随着美国西方化工公司在纽约州尼亚加拉瀑布地区的氯甲苯装置的停产,甲苯环氯化的市场变得很活跃。1996年起耗费2亿美元用于改造和扩产的这个工厂于2000年5月永久地停产了。它的停产使甲苯环氯化市场失去了3.2万吨供应额,而美国却没有可替代的供应商。影响市场的因素还包括:Tessenderlo公司于1997年就通过购买意大利PieveVergonte的爱尼工厂进入氯甲苯市场,英国Widnes公司2001年6月通过购买Atochem(阿托化工)进入市场和英国Leek公司于2001年8月购得Acordis进入市场。近来中国生产能力的增长也是不能忽视的。随着对氯甲苯(PTC)的主要的下游产品氟乐灵(tri-fluralin)的迅速减少和2,6-二氯甲苯的衍生物的可能增加,需求方面也有很大的变化。所有这些因素造成了市场的动荡,同时也对甲苯环氯化产品生产者和下游衍生物用户产生影响。
I. INTRODUCTION Recently, the market for toluene-based chlorination has become very active with the discontinuation of the chloromethyl toluene unit of Western American Chemical Company in Niagara Falls, NY. The factory, which cost 200 million U.S. dollars since 1996 for renovation and expansion, was permanently discontinued in May 2000. Its shutdown halted the supply of 32,000 tonnes of toluene in the chlorinated market, while the United States did not have an alternative supplier. Other factors affecting the market include: Tessenderlo entered the chlorotoluene market in 1997 at the Aini factory in Pieve Vergonte, Italy, Widnes entered the market in June 2001 through the purchase of Atochem and Leek in the UK in 2001 Acordis acquired in August to enter the market. Recently, the growth of China’s production capacity can not be ignored either. There has also been a dramatic shift in demand with the rapid decrease of tri-fluralin, the major downstream product of p-chlorotoluene (PTC), and the possible increase of derivatives of 2,6-dichlorotoluene. All of these factors have contributed to the market turmoil and have also had an impact on producers of tolylchlorinated chlorinated products and users of downstream derivatives.
