Description
Summary:The aim of the work is to study the textural characteristics of zinc acetate catalyst impregnated with activated carbon in different ways. Here for the first time studied the properties of carbon sorbents obtained on the basis of FC modified with acetic acid or hydrogen peroxide as carriers for zinc acetate catalysts of vinyl acetate synthesis. It was found that the adsorption process in modified coal is strongly dependent on the hydrodynamic regimes, the adsorption conduction temperature, the initial salt concentration and the initial value of the pH solution. Adsorption isotherms were obtained on the surface of the modified FC, which belongs to the Langmuir type of adsorption isotherms. On the surface of the modified sorbents (T=50°C, solution rotation rate 15±2 cm/sec, initial values pH=5.5-6.0 and C0(Zn(OAc)2= 20% mass.). Optimal conditions of zinc acetate immobilization corresponding to catalytic activity were established. The obtained catalysts were studied by small-angle scattering of X-rays, scanning electron microscopy, and X-ray microanalysis methods.
