Method for preparing of optically pure R-form or S-form tetrahydro furfuryl alcohol using heterogeneous catalysts

摘要

The present invention is optically pure (R) using a heterogeneous catalyst in the presence of a foam-tetrahydro fur relates to a method for manufacturing a furyl alcohol (Tetrahydrofurfuryl alcohol), more specifically, a heterogeneous catalyst and an organic solvent - form or (S) (R) - form or (S) - form 2-tetrahydrofuran-acid ester (tetrahydro-2-furoic acid ester) the optically pure (R) was reduced via hydrogenation - form or (S) - tetrahydro-form It relates to a method for producing a fur-furyl alcohol. According to the invention, it can provide a clean technology that can maintain a high optical purity in a continuous hydrogenation reaction applying the heterogeneous catalyst. In addition, the manufacturing method according to the present invention is a simple process, yet excludes the extraction process is environmentally friendly process does not use toxic substances, increased production efficiency per hour has a mass production is easy due to the economic advantage on an industrial scale it is. ; (R) - tetrahydro-Fur furyl alcohol, (S) - tetrahydro-Fur furyl alcohol, 2-tetrahydrofuran ester, optically active, heterogeneous catalyst, hydrogenated
