Adkins also coined the word " hydrogenolysis " to describe the chemical reaction in which a molecule is broken into smaller molecules by the reaction of hydrogen.
12.
This can be further subdivided into two types of reaction processes, the first of which, hydrogenolysis, is the replacement of the halogen atom with a hydrogen atom.
13.
The conversion of CO to alkanes involves hydrogenation of CO, the hydrogenolysis ( cleavage with H 2 ) of C O bonds, and the formation of C C bonds.
14.
Catalytic hydrogenolysis of an ester is the analogous reaction with a high atom economy, but it requires catalyst optimization, is a much slower reaction and is not applicable universally.
15.
Benzyl groups can be removed by catalytic hydrogenolysis over palladium on carbon, and tertiary-butyl groups can be removed by treatment with trifluoroacetic acid, or boiling aqueous acetic acid.
16.
Diethyl malonate can be nitrosated with excess sodium nitrite in acetic acid to afford diethyl oximinomalonate, catalytic hydrogenolysis of which in ethanol over Pd / C affords diethyl aminomalonate ( DEAM ).
17.
Thus, a poison that covers surface randomly will tend to reduce the number of uncontaminated large planes but leave proportionally more smaller sites free, thus changing the hydrogenation vs . hydrogenolysis selectivity.
18.
Laboratory hydrogenolysis is operationally similar to hydrogenation, and may be accomplished at atmospheric pressure by stirring the reaction mixture under a slight positive pressure of hydrogen gas, having flushed the apparatus with more of this gas.
19.
Achmatovicz s discovery of catalytic hydrogenolysis was assessed by the board of faculty as an important contribution to the advancement of degradation methods in organic chemistry and for this work Achmatowicz received the title of docent in 1933.
20.
From the hydrogenolysis, the final products are the high-molecular-weight alcohol, which is recycled back to the esterification, and the corresponding primary alcohols ( e . g ., ethanol, propanol, butanol ).
