If the acyl groups are different, then they are named in alphabetical order in the same way, with anhydride replacing acid and IUPAC name consists of three words. For example, CH 3 CO−O−OCCH 3 is called ethanoic anhydride and CH 3 CO−O−OCCH 2 CH 3 is called ethanoic propanoic anhydride.
Formic anhydride is a liquid with boiling point 24 °C at 20 mmHg. [3] It is stable in diethyl ether solution. It can be isolated by low-temperature, low-pressure distillation, but decomposes on heating above room temperature. [ 3 ]
It also maintains List I of chemicals and List II of chemicals, which contain chemicals that are used to manufacture the controlled substances/illicit drugs. The list is designated within the Controlled Substances Act [ 1 ] but can be modified by the U.S. Attorney General as illegal manufacturing practices change.
