A catalyst containing 10 mol-% calcium oxide gave the best ethanol conversion and acetone selectivity. What happened was that the alkene in the diphosphine was hydrogenated by hydrogen formed from the isopropanol being converted partly into acetone. There are several ways to convert isopropanol to acetone. Both acetone and isopropanol are readily available and cheap chemicals.

Appreciable steady-state catalytic activity was achieved only when oxygen was present in the reactant gas flow. such as in biomedical applications. Acetaldehyde (systematic name ethanal) is an organic chemical compound with the formula CH 3 CHO, sometimes abbreviated by chemists as MeCHO (Me = methyl).It is one of the most important aldehydes, occurring widely in nature and being produced on a large scale in industry.Acetaldehyde occurs naturally in coffee, bread, and ripe fruit, and is produced by plants. Color changes of a solution of acetone and sodium hydroxide. The crude acetone (collected below 65'), and Neither the Wikipedia article nor the cited source provide much information on this. This can be achieved using oxidizing agents such as chromic acid, or by dehydrogenation of isopropyl alcohol over a heated copper catalyst: $$\ce{C3H8O -> C3H6O + H2}$$.

SQL Server - Benefits of splitting databases across different logical drives, Determining CRS from given point coordinate set. The effect of mild pretreatment of $\ce{Cr2O3}$ in $\ce{O2–N2}$ at 473 K on the initial activity, and the observed dependence of the process on $\ce{O2}$ pressure has been related to the oxidation–reduction cycle of the surface chromium species.
