An alcohol compound is produced by reducing a carboxylic acid or an ester thereof with an alcohol in the presence of a solid catalyst. The catalyst includes a hydrous metal oxide belonging to Group IV of the Periodic Table.SHIBAGAKI MAKOTO...
Lignosulfonates are obtained as a by-product from the acid sulfite wood-pulping process, and in their crude form contain many impurities such as pentose and hexose sugars. The latter are powerful retarders and are removed by fermentation followed by distillation of the resulting alcohol if the li...
Preferably, in the case in which the reducing agent R2 employed has a protonated function such as a carboxylic acid or an alcohol, it is preferred to add a base to the aqueous solution containing said compound R2 in the protonated form. More preferably, said base is sodium hydroxide. Adding...
