Hydrogen carboxylic acid

If they are also united to hydrogen, carboxylic acids are formed, otherwise ketones. [Pg.112]

Carboxylic acids are one of the most difficult of all functional groups to hydrogenate. They can be hydrogenated to the alcohol, however, over ruthenium 34 or rhenium heptoxide 35,136 t 150°-200°C and 300-400 atmospheres pressure. Activated Cu-Ba-CrO is also effective at 250°-300°C and 300-400 atmospheres (Eqn. 18.31). 3 A Re-Os bimetallic catalyst has been used to hydrogenate carboxylic acids at 100 -120°C and 20-100 atmospheres of hydrogen. High conversions to the alcohol were reported. 38... [Pg.462]

Hydrogenation. Carboxylic acids are reduced to aldehydes by hydrogen in the presence of (PhjPl Pd and pivalic anhydride. Alkenoic acids (oleic acid, erucic acid) give unsaturated aldehydes. Diacids are similarly reduced. [Pg.362]

Introduction.—The oxidative dehydrogenation of alcohols to aldehydes and ketones over various catalysts, including copper and particularly silver, is a well-established industrial process. The conversion of methanol to formaldehyde over silver catalysts is the most common process, with reaction at 750—900 K under conditions of excess methanol and at high oxygen conversion selectivities are in the region 80—95%. Isopropanol and isobutanol are also oxidized commercially in a similar manner. By-products from these reactions include carbon dioxide, carbon monoxide, hydrogen, carboxylic acids, alkenes, and alkanes. [Pg.90]

In this region occur the broad bands of many acidic hydrogens. Carboxylic acid dimers absorb broadly near 3000 cm" with satellite bands near 2650 and 2550 cm . Amine salts absorb in this region. Their bands have much fine structure. Phosphorus acids absorb broadly in this region. The strongly bonded hydrogen in the enol form of 1,3-diketones and related compounds absorbs broadly at 3100-2700 cm ... [Pg.389]
