| titleOfInvention | Process for the preparation of methyl 4-oxobutyrate and its methanol addition products |
| abstract | Methyl 4-oxobutyrate and its methanol addition products, methyl 4,4-dimethoxybutyrate and gamma-methoxy-gamma-butyrolactone, which are useful as intermediates in the preparation of such industrially important compounds as gamma-butyrolactone, 1,4-butanediol and glutamic acid, are produced from the reaction of acrolein, carbon monoxide and methanol in the presence of a catalyst system which consists of (a) a Group VIII metal component selected from palladium metal or a palladium-containing composition which generates palladium metal under reaction conditions, (b) a hydrogen halide and (c) an arylarsine catalyst copromoter. |
