Dynamic Studies on Accelerating Agents for Vulcanization on 13X Zeolites

Abstract

Abstract: In this paper, the acid character on the surface of 13Xzeolites and the dynamic behavior of accelerating agents for vulcanization on 13X zeolites are studied by TPD.The results obtained show that there are differenet acid sites on the zeolites for the base adsorbates, such as Bacid, Lacid, mixing Band Lacids, and weak chemical adsorption.The effective sites on the surface for adsorption is the sites of weak chemical adsorption for slow-release cross linked agents of adsorption type.It is obtained that different accelerating agents of vulcanization have different dynamic character for their desorption from the surface of 13X zeolites and there is a crystal diffusion in the desorption.

Key words: Adsorption, Desorption, Zeolites, Accelerating agents of vulcanization
