【発明の名称】シクロヘキシルホスホン酸の製造方法
Document Type and Number:
Japanese Patent JP2846326
Kind Code:
B2
Abstract:
A cycloalkyl phosphorus compound is obtained by the catalytic hydrogenation of a substituted or unsubstituted aryl phosphonic acid using a heterogeneous catalyst which is a Group VIII metal on carbon. The hydrogenation is preferably effected in water. The catalyst can be ruthenium on carbon. When phenylphosphonic acid is used as the starting material, a yield of about 95% of essentially pure cyclohexylphosphonic acid can be obtained.
