Reactions of alkylene oxides with carbon dioxide is the basis of industrial technology of ethylene- and propylene carbonate production. The search for a new catalytic systems for these processes are important because of the possibility of more energy-efficiently production of ethylene- and propylene glycol. The work objective is a comparison of the catalytic activity of halides in the reaction of oxide propylene and carbon dioxide in the presence of tetrasubstituted phosphonium and ammonium halides; a assess the feasibility of their use in industrial technology alkylene carbonate and glycols as active catalytic systems. It is shown that the triphenylphosphine halides more catalytically active than analogues on the basis of triethanolamine. Triphenylphosphine bromides have same effective as a catalysts based on potassium iodide. High activity of these catalysts in the propylene production, as well as good solubility in the reaction mass allows to offer them for development of industrial technology for consistent and alkylene carbonate alkylene glycol.
