Abstract
Bis (phenylglyoxyloyl) benzenes are manufactured by a method comprising the reaction of terephthalic or isophthalic aldehyde first with a low proportion of an alkali metal cyanide in a solvent, and then with benzaldehyde; the resultant product is oxidized to the desired bis (phenylglyoxyloyl) benzene.
