Abstract
Methods of forming a Cto Cdiol compound, the methods including a first step of reacting a Cto Cdicarboxylic acid with hydrogen (H) gas on a first heterogeneous catalyst at a first temperature and a first pressure to form a Cto Clactone; and a subsequent step of reacting the lactone with hydrogen (H) gas on a second heterogeneous catalyst at a second temperature and a second pressure, wherein the second temperature is lower than the first temperature. Also disclosed are methods of forming a solvent, the methods including reacting a Cto Cdicarboxylic acid with hydrogen (H) gas on a first heterogeneous catalyst at a first temperature and a first pressure to form a solvent. Further disclosed herein are methods that include reacting mevalonolactone with hydrogen (H) gas on a second heterogeneous catalyst at a second temperature and a second pressure to form a diol compound.
