甲苯 限于国内生产甲苯的原料——石脑油资源不足,甲苯的生产量一直维持在20—22万吨的水严。随着三套甲苯二异氰酯生产装置的投产,TNT产量的增加,甲苯缺口越来越大,每年都需进口部分资源予以补充。目前,石油甲苯一般市场价格为每吨3000元左右,焦化甲苯一般为2600—2700元/吨。 Toluene is limited to domestic raw materials for the production of toluene—naphtha resources are insufficient, and the production of toluene has been maintained at 20-22 million tons of water. With the production of three sets of toluene diisocyanate production facilities, the production of TNT has increased, and the toluene gap has become larger and larger. Every year, some resources are required to be added. At present, the general market price of petroleum toluene is about 3,000 yuan per ton, and coking toluene is generally 2,600-2,700 yuan per ton.
