Summary:PROBLEM TO BE SOLVED: To provide a method for manufacturing lithium 12-hydroxystearate less in contamination of contaminants deteriorating silence of a grease.SOLUTION: The manufacturing method of lithium 12-hydroxystearate is a manufacturing method of lithium 12-hydroxystearate obtained by reacting 12-hydroxystearic acid and excessive amount of lithium hydroxide monohydrate and lithium 12-hydroxystearate as a reaction product is applied to a washing treatment by a solution containing water. In the washing treatment, it is preferable to mix the lithium 12-hydroxystearate and the solution containing water at a ratio of 50:50 to 10:90 for washing. Also the solution containing water is preferably contains a surfactant.SELECTED DRAWING: None 【課題】グリースの静粛性を損なわせる夾雑物の混入の少ない12−ヒドロキシステアリン酸リチウムを製造するための方法を提供する。【解決手段】本発明に係る12−ヒドロキシステアリン酸リチウムの製造方法は、12−ヒドロキシステアリン酸と過剰量の水酸化リチウム一水和物とを反応させて得られる12−ヒドロキシステアリン酸リチウムの製造方法であって、反応生成物である12−ヒドロキシステアリン酸リチウムを、水を含む水溶液で洗浄処理する。洗浄処理では、12−ヒドロキシステアリン酸リチウムと水を含む水溶液とを、50:50〜10:90の比率で混合して洗浄することが好ましい。また、水を含む水溶液としては、界面活性剤を含有するものであることが好ましい。【選択図】なし
