A mibk reactor

Abstract

The present invention relates to the technical field of organic chemistry, in particular to a MIBK reactor, including an equipment frame and a reaction kettle erected on the equipment frame, and the equipment frame is also provided with: an input pipeline, which is arranged on the equipment frame and leads to the reaction The kettle; the mixing component is set in the inner cavity of the reactor; the output tank body is installed at the processing end of the reactor and is located at the lower level of the reactor; the auxiliary material injection component is erected on the equipment rack; the feeding end of the auxiliary material injection component is set There are feeding parts, which avoid the output end of the input pipeline and are installed on the inner wall of the reactor, and the feeding parts surround the periphery of the output port of the input pipeline; the linkage component is erected on the side edge of the equipment rack, and the linkage The assembly is connected to the power output end of the mixing assembly and the power input end of the auxiliary material injection assembly. The present invention injects deionized water in a decelerated manner when materials are continuously input and mixed, which is convenient for controlling the injection amount of deionized water, and is beneficial for grasping pressure and temperature changes caused by the reaction.

Description

technical field [0001] The invention relates to the technical field of organic chemistry, in particular to an MIBK reactor. Background technique [0002] MIBK, the Chinese name of methyl isobutyl ketone, is a transparent liquid, mainly used as a solvent for spray paint, nitrocellulose, certain fiber ethers, camphor, grease, natural and synthetic rubber. The MIBK production unit is composed of a reactor, an acetone tower, a catalyst tank, a hydrogen storage tank, connecting pipelines and a control system. A deionized water injection pipeline is connected to the pipeline connecting the acetone tower and the reactor, and the deionized water injection pipeline passes through a pump. The valve structure is connected with the deionized water tank, and the side wall of the reactor is provided with a temperature detection point. [0003] For the production reaction of MIBK, in the deionized water injection link, the stability of the reactor is very insufficient. In the prior art, p...

Problems solved by technology

[0003] For the production reaction of MIBK, in the deionized water injection process, the stability of the reactor is very insufficient. In the prior art, pneumatic valves are generally used to control the water flow rate for cooling and decompression; however, the pneumatic valve The control effect is limited, and the injection of deionized water is related to the reaction process of methyl isobutyl ketone. The present invention is committed to linking the injection of deionized water with the reaction rate of methyl isobutyl ketone for controlling the reaction in the reactor situation
