Reaction distilling apparatus

The invention relates to reaction distillation equipment. It includes reaction chamber and distillation chamber, and reaction is on the top of distillation chamber. There is a feed inlet on the upside of reaction chamber and condensation circumfluence equipment on top. There is a column plate or filling in distillation chamber and discharge gate in bottom. A pipe connects the top of reaction chamber with the top of distillation. A pipe in inverted U shape connects the bottom of reaction with the top of distillation. Horizontal height at connection of pipe and reaction chamber is higher than connection of pipe and distillation chamber. Top of the pipe is over reaction chamber for one third of height and below entrance or exit. The reaction distillation equipment effectively solves the problem that reaction production is removed in time in liquid phase chemical reaction which boiling point of reaction production is higher than other materials. Adopting the invention, highly pure reaction production can be obtained simultaneously.
