FIELD: rubber industry. SUBSTANCE: azomethine-type accelerator is prepared by condensation of aniline-containing substance, in particular spent coal adsorbent used for treatment of aniline production waste water (particle size 0.01-2.0 mm, aniline content 0.4-0.45 g/g coal), with an aldehyde. EFFECT: improved process properties of accelerator and reduced cost price. 3 ex
