Zusammenfassung:TITLE PREPARATION OF ACETIC ANHYDRIDE The preparation of acetic anyhydride by the carbonylation of methyl acetate in the presence of rhodium, an iodine compound and lithium at elevated temperatures and pressures is improved by the inclusion of about 2 to 7 volume percent hydrogen in the gas feed to the carbonylation reactor. The presence of hydrogen suppresses tar formation and increases reaction rate.
