In line with the fulfillment of international Minamata Convention and the urgent need for developing non-mercury catalysts, Au-Lx/AC catalysts were synthesized and evaluated for the hydrochlorination of acetylene. The results showed that the interaction between ligands and Au species contributed to the enhanced catalytic activity with important and different roles of each ligand. Depending on the high electronegativity of heteroatoms, all the prepared catalysts had effectively improved their adsorption and activation capacity of hydrogen chloride. Specifically, the N-containing ligands in catalysts increased the dispersion of Au species and an enhanced adsorption of acetylene was observed While, the coordination of P-containing ligands with Au can increase the relative content of active Aun+ species and the O-containing ligands rather decreased the adsorption of acetylene. Furthermore, all the prepared Au-Lx/AC catalysts showed good stabilities based on the inhibition of the agglomeration of Au components or of coking deposition. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Synthetic Route of C4H12ClN).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Synthetic Route of C4H12ClN
