Resumo
An alternative solvent for the production of epichlorohydrin via the epoxidation of allyl chloride with an aqueous hydrogen peroxide solution over a heterogeneous catalyst based on a granulated titanium-containing zeolite has been selected. The problem of replacing toxic methanol with other solvents, which provide, in particular, a simplification of the separation flowsheet, has been solved. Five water–allyl chloride–epichlorohydrin–solvent–heavily boiling fraction five-component systems have been studied (methanol, ethanol, propanol-1, propanol-2, and butanol-1). A thermodynamic topological analysis of phase equilibrium diagrams and an assessment of the possibility and feasibility of separating the mixtures via a method based on a combination of distillation and splitting have been conducted. The most promising solvent for the allyl chloride epoxidation reaction is propanol-2.
