Dehydration of maleic acid utilizing monohydric alcohols as a dehydration or entraining agent. A hydrocarbon is oxidized to maleic anhydride and reactor effluent scrubbed with water to form aqueous composition of maleic acid which is dehydrated with n-butanol in a distillation column. Mixture of n-b...
