説明

Magnesium stearate was prepared by heating stearic acid and magnesium hydroxide, The process of this reaction was discussed by means of differential thermal analysis, Magnesium hydroxide easily reacted upon with stearic acid under 100°, but neither magnesium oxide nor basic magnesium carbonate easily reacted upon with stearic acid. The mixture of magnesium stearate and stearic acid generally showed a complicated D. T. A. curve, and the figure of the curve varied according to mixing state. However, the mixture previously melted showed a characteristic curve, which was similar to that of reaction products, and it was possible to estimate the ratio of magnesium stearate to stearic acid in reaction products.
