PROCESS FOR PRODUCING HIGH-PURITY CHOLESTEROL

摘要

A process for producing high-quality cholesterol by selectively reducing impurities contained in crude cholesterol, mainly desmosterol, into cholesterol. The process can provide high-purity cholesterol containing at most 0.3 % of desmosterol and at most 0.5 % of dihydrocholesterol and having a purity of at least 99 % after reduction and crystallization in a yield of 85 % or above.
