硬脂酸鎂的制造多系以氢氯化鈉硷化硬脂酸。在制造时必须准确掌握氫氧化鈉的用量,多則过剩的氫氧化鈉在加入硫酸鎂时与硫酸鎂相結合,生成不溶性的氢氧化鎂混入产品中,影响硬脂酸鎂的光滑度;少则硬脂酸硷化不完全,有游离的硬脂酸存在,在烘干时容易熔化,破坏硬脂酸鎂的結晶。因此欲制得滿意合格的硬脂酸镁,就必须事先对所用的氫氧化钠进行测定和计算蛭獨溲趸c易于吸收CO_2和水分,为了准确,
Magnesium stearate is manufactured by dissolving stearic acid with sodium hydrogen chloride. It is necessary to accurately determine the amount of sodium hydroxide used in the manufacture, and most of the excess sodium hydroxide is combined with magnesium sulfate when magnesium sulfate is added, and insoluble magnesium hydroxide is mixed into the product to affect the smoothness of the magnesium stearate; The stearic acid deuteration is not complete, there is free stearic acid, easy to melt during drying, destroy the crystals of magnesium stearate. Therefore, to obtain a satisfactory qualified magnesium stearate, it is necessary to measure and calculate the sodium hydroxide used in advance, so that it is easy to absorb CO 2 and moisture. For the sake of accuracy,
