Abstract
The invention belongs to chemical fields, and in particular to a method of magnesium citrate is prepared using ultrasound cavitation effect, products application is in food and medicine field.The present invention is carried out using ultrasound cavitation effect regulation reaction, has prepared magnesium citrate product.Accelerate the solution rate of magnesium carbonate by ultrasound cavitation effect, promotes the progress of magnesium carbonate and citric acid reactions, promote the synthesis of magnesium citrate.Magnesium citrate product obtained has the advantages that purity is high, partial size is small, particle diameter distribution is uniform.The characteristics of this method has simple process and low cost, is suitable for large-scale production.
Description
Technical field
The invention belongs to material chemistry technical fields, and in particular to a kind of to prepare magnesium citrate using ultrasound cavitation effect
Method.
Background technique
Magnesium citrate is white particle or crystalline powder, is dissolved in diluted acid, is slightly soluble in water and alcohol.Its content of magnesium is up to percentage
11, since magnesium component is easy to be absorbed by the body, is a kind of critically important magnesium nutrition source, seeks it often in health care
It supports and is used in tonic.Magnesium citrate has good medical application as physiological saline laxative.Before doing any operation, meeting
Magnesium citrate is provided to patient, in order to empty enteron aisle.This is because it has the tendency that absorptive tissue moisture, it can after injection enteron aisle
Largely to absorb water and excrete.
Currently, the research in relation to the preparation of magnesium citrate material is concentrated mainly in raw material and edibility.Although lemon
Sour magnesium has preferable application prospect, when current preparation method be limited only to chemical coprecipitation (CN201010202554.1,
CN200810043404.3 etc.), preparation method is excessively single.
The present invention obtains a kind of powdered magnesium citrate material, proposes the conjunction that the material is prepared using ultrasound cavitation effect
At method, the deficiency of existing magnesium citrate material preparation method is compensated for.The method that the present invention uses has equipment simple, reaction
It is simple and easy, just with production, the features such as can in high volume making.
Summary of the invention
It is an object of the invention to propose a kind of method for preparing magnesium citrate material using ultrasound cavitation effect, solve
The problem of existing magnesium citrate material preparation method deficiency.
The present invention proposes a kind of method for preparing magnesium citrate material using ultrasound cavitation effect, utilizes ultrasound cavitation effect
It is prepared, the specific steps are that:
Citric acid and magnesium carbonate are added in reaction kettle together with suitable quantity of water according to 2: 3 ratio of molar ratio, in ultrasound condition
Magnesium citrate solution is made in lower reaction 20-30 minutes, is washed with deionized after crystallization, dry magnesium citrate powder.
Specific preparation condition are as follows:
Raw material usage are as follows: the mass ratio of citric acid and magnesium carbonate is 1.52: 1；
Ultrasound condition: ultrasonic power 200-1000W, reaction time are 20~30min；
Material drying: drying temperature is 50~70 DEG C, and drying time is 8~12h；
The color that the present invention obtains product after drying is clear crystal.
The present invention has the advantage that
1, the present invention has the advantages of accelerating magnesium carbonate solution rate by ultrasonic method, magnesium citrate is promoted to be synthetically prepared.
2, the invention proposes the ultrasonics for preparing the material, compensate for existing magnesium citrate material preparation method
It is insufficient.
3, the raw material sources used in the present invention are abundant and cheap, and preparation process is simple.
