Abstract

The invention discloses a synthesis method of magnesium taurate, and relates to the technical field of health food. The synthesis method of the magnesium taurate comprises the following steps: (1) keeping the temperature of water at 65-75 DEG C, stirring, adding taurine, then adding magnesium oxide, stirring for a period of time to obtain a mixed solution A, cooling the mixed solution A, and continuously stirring to obtain a mixed solution B; (2) filtering or centrifuging the mixed solution B obtained in the step (1) to obtain a filtrate I and a solid I, cooling the obtained filtrate I, and filtering or centrifuging to obtain a filtrate II and a solid II; (3) evaporating and concentrating the filtrate II obtained in the step (2) to obtain a concentrated solution, and continuously stirring, filtering or centrifuging to obtain a filtrate III and a solid III; and (4) washing and drying the solid III obtained in the step (3) to obtain the magnesium taurate. The invention provides a synthetic method of magnesium taurate which does not need an organic solvent and is high in separation purity.

Description

technical field [0001] The invention relates to the technical field of health food, in particular to a synthesis method of magnesium taurate. Background technique [0002] At present, the synthesis of magnesium taurine, the mainstream method is that taurine and magnesium oxide (or magnesium hydroxide, etc.) react in the aqueous phase with a molar ratio of 2:1, and then add organic solvents such as methanol to make taurine Magnesium precipitates. The prior art has the following disadvantages: (1) taurine and magnesium oxide in a molar ratio of 2:1, magnesium oxide is difficult to react completely; (2) the solution system obtained after the reaction is a mixture of magnesium taurine and taurine, which is not easy to (3) needs to use organic solvent; (4) magnesium taurate solution system is prone to hydrolysis under certain conditions, generates magnesium hydroxide. Magnesium taurine molecular formula Mg[H 2 NC 2 h 4 SO 3 ] 2 , the typical equation for the reaction of ta...
