凯茵化工讯 德国化工巨头巴斯夫10月12日宣布，召回在欧洲销售的甲苯二异氰酸酯(TDI)产品，原因是这些TDI含有过量二氯苯。

　　巴斯夫表示，近日发现路德维希港所生产的TDI出现质量波动。该生产基地于2017年8月25日至9月29日间所生产交付的TDI含有过量二氯苯(DCB)，原因是生产过程中出现了技术缺陷，现正在排除。

　　巴斯夫已通知受影响的约50家客户，并停止交付该产品。巴斯夫确认受影响的材料并未直接销往亚洲。亚洲地区的TDI生产装置未受波及，未发现同类质量问题。

　　在二氯苯含量超标的7500吨TDI中，约有三分之二尚未进一步加工，巴斯夫正召回这部分产品。

　　对于已加工的产品，巴斯夫目前正积极与相关客户进行沟通，包括一个由75名专家组成的团队正帮助橡胶增塑剂客户检测二氯苯含量，防止任何危害的发生。

　　巴斯夫称，已采取以下措施：正召回未经加工处理的TDI以及未经加工处理的泡沫块，预计在下周末完成召回。对于已加工的产品，巴斯夫正协助客户进行相关测试，确保产品符合不同行业的具体要求。

　　据悉，二氯苯是一种无色的液态有机化合物，如进入水体，对水生生物具有持续的毒性，可造成皮肤、呼吸道和眼部刺激及皮肤过敏，有致癌的可能性。

　　TDI(甲苯二异氰酸酯)是用于制造聚氨酯的重要原料，主要应用于家具行业(如床垫的弹性泡沫、垫子或木器涂料)以及汽车行业(汽车座垫)。

Excessive Dichlorobenzene BASF recalled thousands of tons of TDI in Europe

Kailin Chemical News German chemical giant BASF announced on October 12 the recall of tolylene diisocyanate (TDI) products sold in Europe because these TDI contained excess amounts of dichlorobenzene.

BASF said it has recently discovered a fluctuation in the quality of its TDI produced in Ludwigshafen. The TDI delivered at this site from August 25 to September 29, 2017, contains excess amounts of dichlorobenzene (DCB) due to technical shortcomings in the manufacturing process and is currently being excluded.

BASF has notified about 50 affected customers and stopped delivering the product. BASF confirmed that the affected materials were not sold directly to Asia. TDI production facilities in Asia have not been affected, and no similar quality problems have been found.

About two-thirds of the 7,500-ton TDI with excessive dichlorobenzene content has not yet been processed and BASF is recalling some of these products.

For processed products, BASF is actively engaged with relevant customers, including a team of 75 experts who are helping customers detect dichlorobenzene content and prevent any hazards.

BASF said it has taken the following measures: It is recalling unprocessed TDI and unprocessed foam blocks and is expected to complete the recall by the end of next week. For processed products, BASF is assisting customers with the relevant tests to ensure that the products meet the specific requirements of different industries.

It is reported that dichlorobenzene is a colorless liquid organic compound, such as into the water, have persistent toxicity to aquatic organisms, can cause skin, respiratory and eye irritation and skin allergies, carcinogenic may Sex.

TDI (tolylene diisocyanate) is an important starting material for the manufacture of polyurethanes and is mainly used in the furniture industry such as elastic foam for mattresses, mattresses or wood coatings, and in the automotive industry (car seat cushions).
