| abstract | 1,259,145. Methyl ethyl ketone. MARUZEN OIL CO. Ltd. 14 Oct., 1969 [14 Oct., 1968], No. 50541/69. Heading C2C. Methyl ethyl ketone is prepared by contacting a C 4 -hydrocarbon mixture containing 1-butene with an isomerization catalyst capable of producing double-bond migration, at a temperature of from 0‹ to 300‹ C. under a pressure of from atmospheric to 50 atmospheres and contacting the C 4 -hydrocarbon mixture rich in 2-butene so obtained with an aqueous catalytic solution containing a water-soluble palladium compound and ferric sulphate. The palladium compound is suitably an inorganic palladium salt such as the sulphate, nitrate or chloride or may be palladium potassium chloride, whereas the isomerization catalyst is suitably sodium, lithium, platinum, nickel or palladium, a portion of the latter preferably being sulphurized. The carbonyl reaction is preferably carried out at from room temperature to 200‹ C. under a pressure sufficient to maintain at least the aqueous solution in the liquid phase. The aqueous solution may additionally contain a halogen ion, e.g. chlorine supplied by, e.g. including a metal halide or a hydrogen halide in this solution. Examples describe the preparation of MEK, the principal by-product being t - butanol together with smaller amounts of see-butanol, n-butyraldehyde, acetone and 3-chlorobutanone. |
