Who produces DBP using non-acidic catalysts?
Thread Content
Does anyone know which manufacturer in the plasticizer industry uses non-acidic catalysts to produce dibutyl phthalate (DBP)?
I once helped Jinling conduct experiments with this catalyst in production about 20 years ago. Using experimental data from non-isothermal batch reactions, the kinetic equations for the catalytic synthesis of dioctyl phthalate by the new catalyst QS-6 and the conventional catalyst tetrabutyl titanate were respectively derived, thereby establishing an operating model for a real stirred reactor. By using kinetic equations and the established operational model to simulate the operating characteristics of actual industrial plants and conduct scale-up studies, it was found that both catalysts can meet the design requirements. Comparison showed that when the amount of QS-6 catalyst used was 35%–40% of that of the tetrabutyl titanate catalyst, its activity remained higher than that of the tetrabutyl titanate catalyst
