According to the invention, the device is ingenious in structure, ice blocks can be rapidly mixed into mixed liquid and rapidly and uniformly mixed, the using amount of the ice blocks can be reduced in the uniform mixing process, the subsequent distillation cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of hydrolysis reaction devices, in particular to a hydrolysis reaction device for neotame production. Background technique [0002] In the production process of neotame, 3,3-dimethylbutyraldehyde is an important intermediate in the production of neotame. In the production process of 3,3-dimethylbutyraldehyde, dichloromethane is required as a solvent, chlorine tert-butane and vinyl acetate are used as raw materials. After being catalyzed and synthesized by a metal catalyst, ice cubes are added for hydrolysis and distillation to obtain 3,3-dimethylbutyraldehyde. In this process, because the reaction is relatively rapid, the reaction can be completed within 2-15 seconds. Therefore, if ice cubes cannot be quickly added to the mixture and the mixture is mixed uniformly, the problem of excessive local reaction temperature will occur, affecting Hydrolysis, so the existing technology centers often need to add a large amount ...

Problems solved by technology

In this process, because the reaction is relatively rapid, the reaction can be completed within 2-15 seconds. Therefore, if ice cubes cannot be quickly added to the mixture and the mixture is mixed uniformly, the problem of excessive local reaction temperature will occur, which will affect Hydrolysis, so the existing technical centers often need to add a lot of ice cubes or water in order to ensure sufficient hydrolysis, and this will increase the time and cost of subsequent distillation, so we designed a hydrolysis reaction device for neotame production
