Embodiment Construction
[0027] The technical solution of the present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.
[0028] Take the production of butyl acetate as an example.
[0029] In the rectification tower system, butanol and acetic acid proportioned according to the reaction equation pass through the raw material preheater 16 (E3105), and are added from the upper part of the rectification tower tank (T3101), and the liquid reaction liquid containing catalyst and raw materials is in the rectification tower The esterification reaction takes place in the tower kettle 2. The final butyl acetate product material provides a heat source for the raw material preheater 16 (E3105) to heat the mixed raw material to save energy.
[0030] Under the action of potential difference, self-gravity and siphon force, the material in the natural convection pipe at the bottom of the distillation column 2 and the condensate in the overflow weir 6 are...
