Continuous kettle type 2, 6-methyl ethyl phenyl-methylenimine production device and method

Abstract

The invention discloses a continuous kettle type 2, 6-methyl ethyl phenyl-methylenimine production device and method, and belongs to the technical field of chemical engineering, the continuous kettle type 2, 6-methyl ethyl phenyl-methylenimine production device comprises a plurality of reaction kettles, the plurality of reaction kettles are sequentially connected in series through overflow pipelines, the reaction kettle at the head end of series connection is set as a feeding kettle, the reaction kettle at the tail end of series connection is set as a discharging kettle, the feeding kettle is connected with a plurality of feeding pipes, and the discharging kettle is connected with a plurality of discharging pipes. The discharge kettle is connected with a receiving tank through an overflow pipeline, the reaction kettles are connected with a condensate pipe and a steam pipe, top gas-phase regions of the reaction kettles in front of the discharge kettle are connected with the side surface of the bottom of the purification tower through gas-phase balance pipes, and the top gas-phase region of the discharge kettle is connected with the extraction tower. Raw materials enter the feeding kettle through the feeding pipe, steam is fed into the reaction kettles through the steam pipe, so that stable pressure and temperature are kept in the reaction kettles, and a mixture of the raw materials sequentially flows through the reaction kettles through the overflow pipeline for reaction synthesis and finally flows into the receiving tank to be collected, so that continuous reaction synthesis is realized; operation is stable and simple, automation degree is high, and reaction effect is good.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a continuous kettle type 2,6-methylethylphenyl-methanimine production device and method. Background technique [0002] During the synthetic production of 2,6-methylethylphenyl-methimine, it is produced by batch method. During the production process of batch method, auxiliary operations such as loading and unloading are required, which will easily cause the loss of materials and energy. Operation Complex, long cycle, and unstable product quality, and the reaction waste gas and waste water are easy to leak during loading and unloading, which is harmful to the environment and staff. For this reason, we propose a continuous kettle type 2,6-methylethyl The phenyl-formimine production device and method are used to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a continuous tank type 2,6-methylethylphenyl-metha...
