Acetylene hydrochlorination reaction using Au/C catalyst
Thread Content
Are there any industrial plants in China that use Au/C catalysts to produce vinyl chloride from acetylene and hydrogen chloride gases? How does it compare to the HgCl2/C catalyst?

Catalysts that involve mercury in their composition for the addition of acetylene to hydrogen chloride are the most effective; other mercury-free catalysts generally cannot achieve a performance level comparable to those containing mercury. However, mercury is highly toxic, and it is difficult to recycle spent catalysts. Mercury exhibits good catalytic efficiency because, during the reaction process, it does not easily form aggregated states; its high degree of dispersion is the key factor behind its excellent catalytic performance.
