Palladium carbon is insoluble in all organic solvents and acidic solutions, has a neutral pH value and a high specific surface area (1000-1200m²/g). Its effective substance content is usually 0.5%, 5% or 10%, and the packaging is based on customer needs.
The preparation method of palladium carbon is to load metal palladium powder on activated carbon. Palladium carbon catalyst is widely used in the hydrogenation reduction refining process of petrochemical industry, pharmaceutical industry, electronics industry, fragrance industry, dye industry and other fine chemicals. It has the characteristics of high hydrogenation reduction, good selectivity, stable performance, small feed ratio during use, repeated application, and easy recycling.
The recovery method of palladium carbon is usually to dissolve the waste palladium carbon in ethanol, pump it into the autoclave through negative pressure, then add ethanol to wash the container, and recover the palladium carbon through the filter after the reaction is completed.
