ABSTRACT:
A process for the stabilizing of an organosilane with an effective, stabilizing amount of purified N,N'-diphenyl-p-phenylenediamine (DPPD). The purification of crude DPPD involves extracting crude DPPD with hexane thereby forming an extract solution containing DPPD, passing the extract solution over an adsorption layer comprising silica gel as the adsorbent to form a solution containing purified DPPD and recovering the purified DPPD from the solution.
