acetic anhydride structure
Why is acetic anhydride?
Acetic Anhydride is a colorless liquid with a characteristic sharp odor.
It is used in making plastics, drugs, dyes, perfumes, explosives and aspirin. * Acetic Anhydride is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, NFPA and EPA.What is the structure of acid anhydride?
Acid anhydrides contain two acyl groups and have the general formula RC(=O)OC(=O)R or acyl—O—acyl.
The acyl groups may be the same (symmetric) or different (asymmetric or mixed).
The simplest and most common acid anhydrides are symmetrical derivatives of monobasic acids.
