Molecular formula : C36H70MgO4
MW : 591.27
CAS No. :557-04-0
nature : loose white powder. 108-115 ¡ã C melting point, the relative density of 1.07. Solubility in water at room temperature 77-79mg / L, dissolved in hot ethanol. Case acid and stearic acid decomposition of the corresponding magnesium salt. A special micro-foul, stirring flu.
Preparation : stearic acid plus sodium hydroxide saponification tougher sodium, magnesium sulfate with double decomposition in magnesium stearate. Stearic acid and will respond pot of water, heated to 85 ¡ã C, stirring dissolve, slowly joined preheating to 75 ¡ã C sodium hydroxide solution. After saponification, the temperature controlled at 72 ¡ã C, stirring slowly under 55 to join preheating ¡ã Cmagnesium sulfate solution. Metathesis rejection after centrifugal water, filter cake washing water sulfate to meet the requirements, then Harvard, air drying, filtration, in products. The yield of 100% stearic acid. Raw material consumption (kg / t) stearic acid (industrial), 960 sodium hydroxide (95%) 140 magnesium sulfate (98%) 410
