Abstract

The present invention relates to salt exchange process of synthesizing dicreatine malic acid. The technological process includes the following three steps: neutralization reaction between creatine and hydrochloric acid or sulfuric acid to produce creatine hydrochloride or creatine sulfate, and neutralization reaction between malic acid and sodium hydroxide or calcium hydroxide to produce sodium salt or calcium salt of malic acid; exchange reaction between creatine hydrochloride or creatine sulfate and sodium salt or calcium salt of malic acid to produce dicreatine malic acid and sodium chloride / calcium chloride or sodium sulfate / calcium sulfate; and membrane separation to eliminate sodium chloride / calcium chloride and to obtain filtrate, concentration, dewatering and stoving to obtain dicreatine malic acid product with high quality and purity over 99.8 %.

Description

Technical field:

[0001] The invention relates to a method for synthesizing dicreatine malic acid. It belongs to the field of organic chemical technology. Background technique:

[0002] Dicreatine malic acid is a new type of health food raw material, which has a very broad market prospect in European and American countries. This product is imported in large quantities from China every year, but all of them are exported after being mixed with bis creatine and malic acid at a ratio of 2:1. Because the impurities contained in the two components are different, the quality is difficult to be guaranteed. Invention content:

[0003] The object of the present invention is to overcome above-mentioned deficiency, a kind of method of producing the dicreatine malic acid of synthetic grade is provided.

[0004] The object of the present invention is achieved like this: a kind of method of synthetic dicreatine malic acid, its processing step is carried out in three steps:

[0005] fi...
