Abstract: In the production of alcohols by gas phase hydrogenation of carboxylic acids or esters at elevated temperature and pressure in the presence of catalysts containing or consisting of group IV oxide(s) as hydrogenation-active constituent, hydrogenation is carried out (a) at 250-400 degrees C and 5-100 bar in the presence of (b) primary or secondary alcohols, using a hydrogen to alcohol molecular ratio ≤ 800.

Abstract: The invention concerns the production of epoxides fromolefins using aromatic peroxycarboxylic acids. Followingepoxidisation (step A), the aromatic carboxylic acids therebyproduced are separated from the epoxides and catalyticallyhydrated (step B) to form the corresponding aromatic aldehydeswhich are then oxidised (step C) with oxygen or with anoxygen-containing gas mixture to form again the aromaticperoxycarboxylic acids which can be used again to produce theepoxides.
