Mprempren, ɔman no mu titiriw anti-aging agent 4020 production nhyehyɛe de p-aminodiphenylamine ne methyl isobutyl ketone di dwuma sɛ raw material inexpensive and not easily poisoned, but the product quality is slightly poor and the yield is low. In addition, a small amount of catalyst powder is introduced into the antioxidant 4020, which is applied to the rubber to affect the quality of the rubber product. Most foreign countries use Pt and other precious metals as catalysts, and the quality and yield are better than domestic ones. The sales price has made up for the sintɔ ahorow a ɛwɔ catalyst cost. sintɔ mprempren, pii a ɛwɔ ɔman no mu anti-aging agent 4020 manufacturers nso reyɛ nhwehwɛmu wɔ precious metal catalysts, nanso industrialized mfiri no nnya nyɛɛ, a ɛno nso yɛ nhwehwɛmu akwankyerɛ titiriw a anti-aging agent 4020 synthesis{19}} Catalyst.
