Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 As shown, the method for converting sodium allanate into aminopropionic acid adopts a continuous ion exchange system with 20 separation units built in the system, and each separation unit is filled with a macroporous strong acid resin; the continuous ion exchange system is divided into five Regions, each of which consists of the following:

[0025] Transformation zone (5#-11#): Contains 7 separation units, divided into two sections, the front section contains 5#-7# separation units, the feed is raw material liquid, the rear section contains 8#-11# separation units, It is the mixed liquid of the intermediate tank; after the raw material liquid enters the 5#-7# separation unit in series in forward direction, its effluent and the effluent liquid in the conversion washing area are mixed into the intermediate tank, and the m...

Abstract

The invention discloses a method for converting sodium aminopropionate into aminopropionic acid, which is characterized in that: a continuous ion exchange system is adopted, and 20 separation units are built in the system, and each separation unit is filled with macroporous strong acid resin; The continuous ion exchange system is divided into five areas: conversion area, conversion washing area, acid regeneration area, regeneration washing area, and material top water area. The average content of aminopropionic acid obtained by the method of converting sodium aminopropionate into aminopropionic acid according to the present invention reaches 9.9%, the purity is >98%, the chloride ion content does not exceed the standard, and the product reverse yield is close to 100%, which has the advantages of It is: compact equipment, simplified system, reduced pipeline and less floor space; reduced resin consumption, reduced consumption of chemicals such as regenerants, and flushing water; the composition and concentration of the product remain basically stable; it has good operating flexibility and can be used according to Changes in production load automatically adjust the rotation speed; reduce operating costs and equipment investment.

Description

technical field [0001] The invention relates to the field of ion exchange, in particular to a method for converting sodium aminopropionate into aminopropionic acid. Background technique [0002] Alanine is a white or light yellow crystalline powder. Its main users are the synthesis of pantothenic acid, calcium pantothenate, carnosine, sodium pamidronate, balsalazide, etc. It is widely used in medicine, feed, food and other fields. At present, there are often disadvantages such as long process, long production cycle, and relatively low total yield in the process of converting sodium allanate into aminopropionic acid. Contents of the invention [0003] For above-mentioned problem, the object of the present invention is to design a kind of method that yield is high, operation is simple, and conversion effect is good sodium aminopropionate is converted into aminopropionic acid. [0004] In order to achieve the above object, the technical scheme proposed by the present inventi...
