METHOD FOR PRODUCING CITRAL HYDRIDE

摘要

Provided is a method for producing a citral hydride, which comprises hydrogenating citral in the presence of hydrogen and a supported-type noble metal catalyst by the use of carbon dioxide in a subcritical or supercritical state as a reaction medium. The method is a novel technique for producing a citral hydride, which allows the synthesis of a citral hydride, in particular, a citral hydride having a high content of geraniol which has a trans isomer purity higher than 98% from citral (which is a cis/trans mixture) with high conversion and high selectivity.
