Dibutyl ketone

In typical processes, the gaseous effluent from the second-stage oxidation is cooled and fed to an absorber to isolate the MAA as a 20—40% aqueous solution. The MAA may then be concentrated by extraction into a suitable organic solvent such as butyl acetate, toluene, or dibutyl ketone. Azeotropic dehydration and solvent recovery, followed by fractional distillation, is used to obtain the pure product. Water, solvent, and low boiling by-products are removed in a first-stage column. The column bottoms are then fed to a second column where MAA is taken overhead. Esterification to MMA or other esters is readily achieved using acid catalysis. [Pg.253]

Instead of acetaldehyde, other aliphatic aldehydes such as propanal or butanal can be applied. Besides MEK, diethyl ketone or dibutyl ketone or even simply n-butane is used. It is worthwhile to point out the significant importance of co-oxi-dizing processes in the mechanistic course of autoxidation reactions. After a short induction time, the intermediates formed act as co-oxidants for the remaining starting molecules. [Pg.454]

The reaction of 3,5-dichloro-A,A-diisopropyl-1 /.4,2,4,6-thiatriazin-l -amine (2) with butyllithi-um gives only dibutyl ketone, probably formed from the ring-transformation product benzoni-trile via butyllithium addition to the ketone imine.45 Reaction of phenylmagnesium bromide with 2 gives 3-chloro-Al,Af-diisopropyl-5-phenyl-lA4,2,4,6-thiatriazin-l-amine (3) in 30% yield.45... [Pg.819]
