主 题：Polyisobutylene succinimide oil dispersion suspension penoxsulam physical stability
摘 要：Oil dispersible suspension concentrates are safe,green,and environmentally friendly *** such as layering,pasting,and bottoming are frequently encountered during the production,storage,and transportation *** succinimide functions as a dispersant and exhibits great potential to improve the physical stability of the oil dispersible suspension *** a microscopic perspective,the sorption characteristics of the polyisobutylene succinimide dispersant T151 on penoxsulam particle surfaces were comprehensively evaluated with XPS,FTIR,and *** T151 adsorption procedure complied with a pseudo-second-order kinetic adsorption model,and it was a kind of physical sorption with an Ea of 22.57 kJ⋅mol^(−1).The T151 sorption model was consistent with the Langmuir *** adsorption process was spontaneous and followed by an entropy ***ΔH^(θ)of dispersant T151 on the surface of penoxsulam particles was 31.59 kJ⋅mol^(−1).The adsorption procedure was endothermic,and the primary force was hydrogen *** XPS results showed that the F and S electronic peaks at the penoxsulam interface decreased,and that the C electronic peak increased significantly after the adsorption of dispersant T151,indicating the adsorption on the surface of penoxsulam *** results of this study provide a vital theoretical basis for the application of polyisobutylene succinimide dispersants in oil dispersible suspension systems.
