use | universal excellent antioxidant for natural rubber, synthetic rubber and latex, excellent protective performance against ozone and flex cracking, and excellent antioxidant for heat, oxygen, light, etc. and general aging. It is often used to manufacture products with high static stress, such as aircraft and automobile tires, bicycle tires, cables, hoses, tapes, rubber rollers and other industrial rubber products. This product is polluting and should not be used in light-colored rubber products. general-purpose excellent antioxidant for natural rubber, synthetic rubber and latex has excellent protective effect against ozone and flex fatigue aging |
production method | p-aminodiphenylamine (I. e. RT beisi) and acetone in the presence of copper-chromium catalyst at 160-165 ℃ and hydrogen pressure 5-6MPa reaction. The reactants are filtered to remove the catalyst while it is hot, frozen, crystallized, filtered, and dried to obtain the finished product. The filtered mother liquor can recover isopropanol by distillation. Raw material consumption (kg/t)RT Beisi 875 acetone 420 catalyst 12 hydrogen 60 |
