| titleOfInvention | PROCEDURE FOR THE SYNTHESIS OF HYDRAZINE DERIVATIVES |
| abstract | Ammonia and aldehydes or ketones are selectively oxidized by hydrogen peroxide to the corresponding azines when they are reacted in the presence of both (a) an amide of a carboxylic acid having a pK greater than about 4.3 and (b) a co-catalyst having the general formula H-X-Y=Z, wherein H is hydrogen, X and Z are each an atom of oxygen or nitrogen and Y is an atom of carbon, nitrogen, arsenic, antimony, phosphorus, sulfur, selenium or tellurium; the atoms of X, Y, and Z carrying other substituents necessary to obey the rules of valence. Preferred co-catalysts include di(alkali metal) hydrogen phosphates, lower dialkyl phosphate esters, bicarbonates and p-toluene sulfonic acid. When 1 DEG or 2 DEG amines are also present, hydrazones are also formed along with the azines. Uses of the resultant products include their hydrolysis to hydrazines with recycling of aldehyde or ketone. |
