Patent Abstracts

MeOH with CO at 200º-300º under 200-1,500 atm. pressure gives AcOMe. Co(OAc)₂ serves as the catalyst. Small amounts of H₂ increase the reaction rate. MeOH 64, Co(OAc)₂5, and H₂O 72 parts, heated in a Ag-lined shaker tube under 600-710 atm. CO at 220º, gave 7% conversion to MeOAc in 0.5 hr. When a mixture of H₂ and CO in the ratio 1:3 was used the conversion was 25% in 0.5 hr. When a mixture of H₂ and CO in the ratio 1:3 was used the conversion was 25% in 0.5 hr.
