WebMaleic anhydride is produced by the oxidation of benzene or butane. Laboratory routes emphasize the dehydration of the corresponding acids. The conditions vary from acid to acid, but phosphorus pentoxide is a common dehydrating agent : 2 CH 3 COOH + P 4 O 10 → CH 3 C (O)OC (O)CH 3 + "P 4 O 9 (OH) 2 " WebMixed anhydrides of carboxylic and sulfonic acids are known, and are powerful acylating agents <71JOC532, 71JOC540 >. These compounds are very susceptible to hydrolysis and decompose on heating, but can be easily obtained by oxidation of thiolesters with ozone or ruthenium tetroxide.
