Reaction device and process for production of acetylacetonate with solid phase method

Abstract

The invention discloses a reaction device and a process for production of acetylacetonate with a solid phase method. The device comprises a motor and a spindle which are mechanically connected, wherein the spindle penetrates through the side wall of a reaction container, the spindle and the reaction container are sealed through a sealing box, the spindle is connected with a stirring paddle, a kettle inside temperature measuring port and a feeding port are formed in the top of the reaction container, a discharging port is formed in the bottom of the reaction container, a jacket is arranged on the outer wall of the reaction container, an acetylacetone feeding tank is arranged above the reaction container, a condensation return device is arranged above the reaction container, a nitrogen filling device a is arranged above the acetylacetone feeding tank, and a micropore spraying device is arranged at the lower part of the acetylacetone feeding tank. The problems that acetylacetone is easilyleaked, local excessive reactions are easily caused during production of acetylacetonate as well as color changing of a product, slow reaction, environmental pollution and material blocking are caused due to temperature rise by use of devices in the prior art are solved.

Description

technical field [0001] The patent of the present invention relates to a reaction device and a process for producing acetylacetonate, specifically, a reaction device and a process for producing acetylacetonate by a solid-phase method. Background technique [0002] The solid-phase method is a new production method of acetylacetonate studied in recent years. The traditional liquid-phase method requires a large amount of water as the reaction medium, which is 10-15 times the amount of acetylacetone added. It will generate a large amount of waste water and consume energy. High, low efficiency, heavy pollution, and low production capacity. [0003] Acetylacetone is a toxic and corrosive liquid. Spilling during the reaction will affect human health and the protection of the environment. The horizontal reactor used in the solid phase method is not tightly sealed or the connections are loose during the production process. , the problem of easy leakage. In addition, the production of...

Problems solved by technology

[0004] The technical problem to be solved by the patent of the present invention is to provide a reaction device and a process for producing acetylacetonate salt by solid-phase method, so as to solve the problem of large amount of waste water, high energy consumption, low efficiency and heavy pollution caused by the production of acetylacetonate salt by liquid-phase method. The shortcoming of low production capacity is to solve the problems of easy leakage of acetylacetone in the existing technology device, local over-reaction in the production of acetylacetonate salt, discoloration of the product due to temperature rise, slow reaction and material blockage
