The invention discloses a mercury-free catalyst for producing and synthesizing vinyl chloride by using noble metal. The mercury-free catalyst comprises 90-95 parts of a carrier, 2-8 parts of mercuric chloride and 2-3 parts of an additive. The activity of the mercury-free catalyst is improved, the service life of the mercury-free catalyst is prolonged, the purity of synthesized vinyl chloride is increased, the production cost of synthesizing vinyl chloride by using noble metal is reduced, and production of vinyl chloride is facilitated.
Description
technical field [0001] The present application relates to the field of mercury-free catalysts, in particular to a mercury-free catalyst for producing synthetic vinyl chloride using precious metals. Background technique [0002] Vinyl chloride, also known as vinyl chloride, is an organic compound and an important monomer in polymer chemical industry. It can be obtained from ethylene or acetylene. Vinyl chloride is a toxic substance. Long-term inhalation and exposure to vinyl chloride may cause liver cancer. The catalyst is " Another name for "catalyst", which acts to change the rate of some chemical process to achieve a desired result. A catalyst is a substance that changes the rate of a reaction without changing the standard Gibbs free enthalpy change for that reaction. The effect is called catalysis, and the reaction involving a catalyst is a catalytic reaction. The catalyst induces a change in the chemical reaction, which makes the chemical reaction faster or conducts the ...
