Molecular structure:
Production process:
Most of Acetic acid by methyl carbonylation synthesis. This reaction, methanol and carbon monoxide to produce acetic acid, equation as follow:
This process is iodomethane as an intermediate, three steps to complete and requires more metal catalyst component (the second step)
(1)CH₃OH + HI →CH₃I + H₂
(2)CH₃I + CO →CH₃COI
1. Stored in a cool, ventilated warehouse.
2. Keep away from the fire, heat. The cold season should maintain a temperature higher than 16 DEG C, to prevent solidification. During cold season, temperature should be maintained above 16 DEG C to prevent/avoid solidification.
3. Keep the container sealed. Should be separated from the oxidant and alkali. Mixing should be avoided by all means.   
4. Use explosion-proof lighting, ventilation facilities.
5. Mechanical equipment and tools that prohibit the use of easy to produce sparks.
6. Storage areas should be equipped with emergency treatment equipment and suitable housing materials.
