It examined both systems, each using two methods of product recovery and purification--direct dehydration and organic solvent recovery. I would not do so on a flask of hexanes. Also (and importantly), ethanol is none too flammable; meaning that I could use a heat gun on a flask of ethanol. Abstract: A process for the recovery of maleic anhydride from the gas produced by the catalytic oxidation of hydrocarbon, n-butane or benzene, is characterized by: a) High efficiency in maleic anhydride recovery; b) Reduced formation of maleic acid … Maleic anhydride is an organic compound with the formula C2H2(CO)2O. 1 2 3.
