Abstract By a specific process,high quality magnesium stearate with good color and luster was cleanly synthesized by the direct reaction of basic magnesium carbanate with stearic acid in aqueous medium under atmospheric pressure without any additive.It was shown that the rate of the synthetic reaction was affected obviously by the reaction temperature and liquid-solid ratio of the feed,and the first rate product of magnesium stearate could be synthesized under the following conditions:reaction temperature is 80 ℃,liquid-solid ratio of the feed is 6∶1,and reaction time is 300 min.Compared with that of traditional technology of double decomposition method,the productivity of this technology was raised and the consumption of energy and water reduced greatly.Since this process can make use of the production equipment in the double decomposition process,it can be adopted by the existing enterprises that originally using the double decomposition process to produce magnesium stearate to restructure in an environmentally friendly way.
