Chemical properties

 Use

●  It is an excellent general-purpose antioxidant for natural rubber, synthetic rubber and latex. It has excellent protection performance against ozone and flexural cracking. It is also an excellent antioxidant for heat, oxygen, light, etc. and general aging. It is often used to manufacture products with high dynamic static stress, such as aircraft and automobile tires, Chemicalbook bicycle tires, cables, hoses, tapes, rubber rollers and other industrial rubber products. This product is polluting and should not be used for light-colored rubber products.

●  Excellent general-purpose antioxidant for natural rubber, synthetic rubber and latex, with excellent protection against ozone and flex fatigue aging

Production method

p-Aminodiphenylamine (ie RT Beisi) reacts with acetone in the presence of a copper-chromium catalyst at 160-165°C and a hydrogen pressure of 5-6MPa. The reactant is filtered off the catalyst Chemicalbook while it is hot, and the finished product is obtained by freezing crystallization, filtration and drying. Isopropanol can be recovered by distillation from the filtered mother liquor. Raw material consumption (kg/t) RT times 875 acetone 420 catalyst 12 hydrogen 60
