对氨基二苯胺简称RT培司,是一种重要的精细化工中间体,可用于橡胶助剂、染料、纺织、印刷及制药工业等,主要用于生产对苯二胺类橡胶防老剂4010NA、4020等。目前在轮胎生产中,西方发达国家4010NA和4020占防老剂使用总量的70%以上。随着我国橡胶助剂的快速发展,刺激和推动了对氨 The amino diphenylamine referred to as RT Pei Si, is an important fine chemical intermediates, can be used for rubber chemicals, dyes, textiles, printing and pharmaceutical industries, mainly for the production of p-phenylenediamine rubber antioxidant 4010NA, 4020 Wait. Currently in the tire production, the western developed countries 4010NA and 4020 accounting for more than 70% of the total amount of antioxidant. With the rapid development of China’s rubber chemicals, stimulate and promote the ammonia
