Acetyl iodide is a chemical compound from the group of carboxylic acid halides and organic iodine compounds .
Extraction and presentation
Acetyl iodide can be obtained by reacting acetaldehyde with iodine .
properties
Acetyl iodide is a red to dark red liquid that is sensitive to light and moisture.
use
Acetyl iodide is formed as an intermediate product in the synthesis of acetic acid during the classic Monsanto process or the Hoechst-Celanese process through rhodium- catalyzed formation from methyl iodide and carbon monoxide . It reacts with water to form hydrogen iodide and acetic acid.
