Magnesium stearate food additiveWhat is the synthesis method? Let's take a brief look together.

　　1. Preparation of sodium stearate: Dissolve 4.25 parts of sodium hydroxide in 50 parts of water, and heat to 85℃ for later use. Add 25 parts of stearic acid to the reaction kettle, add 500 parts of water, dissolve with stirring, and adjust the temperature to 85~90℃. Add the prepared sodium hydroxide solution slowly to the stearic acid aqueous solution with stirring, maintain the temperature at 75~80℃, and react to the end point with stirring. The product sodium stearate solution is kept warm for later use.

　　2. Preparation of magnesium stearate: Dissolve 15 parts of magnesium sulfate in 150 parts of water, heat to 55℃, slowly add to the prepared sodium stearate solution, and carry out a metathesis reaction with stirring. The magnesium stearate generated by the reaction precipitates out in solid form. After the reaction, the clear liquid is allowed to stand and separate, then washed with water, centrifuged, and dried at 80-85℃ to obtain the finished product.

　　3. 50g of sodium stearate in 2L of water was obtained by neutralizing 46.6g of stearic acid with 164ml of 1mol/L sodium hydroxide solution. The prepared sodium stearate solution was heated to 80℃, and a solution prepared by dissolving 20g of magnesium chloride in 100mL of water was added dropwise. After continuous stirring, a white precipitate quickly precipitated, cooled, filtered, washed with water until free of chloride ions, finally washed with ethanol, and 10g of the product was placed in a vacuum desiccator with concentrated sulfuric acid for 4 weeks to obtain product A [Mg(C18H35O2)2·2H2O]. The remaining product was dissolved in benzene, refluxed and heated for 20min, the upper yellow liquid layer was poured out while hot, and the solid obtained after evaporation could be recrystallized from benzene to obtain product B [Mg(C18H35O2)2]. After baking in a 105 oven for 2h, product A was also converted to anhydrous product B.

　　As we age, the efficiency of our bodies in producing nutrients decreases. For example, collagen, as we age, produces less and less, which can also lead to many bone diseases in the elderly. Magnesium stearate food additive is also an indispensable nutrient element in our body. Once we find that our content is too low, we must obtain it from the outside in time, soMagnesium stearate food additiveWhat are the efficacy and effects? Let's take a brief look together.

　　In fact, magnesium stearate food additive mainly acts as a lubricant in our body. Some people, due to work or other reasons, often do not pay attention to diet and rest in life. If this continues for a long time, it will not only put a lot of pressure on their stomach, but also keep them in a state of lack of energy. At this time, you can supplement some magnesium stearate to alleviate your symptoms. This substance can, to a certain extent, speed up the peristalsis of our stomach and intestines, help us digest the food entering our body faster, and if taken for a long time, our mental state will change to a certain extent. Due to its special effect, this substance is often used to manufacture various drugs.
