Molecular structure:
Production process:
Most of Acetic acid is produced by methyl carbonylation synthesis. Methanol and carbon monoxide reacts to produce acetic acid, equation as follow:
CH3OH+CO→CH3COOH
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
(3)CH₃COI + H₂O →CH₃COOH + HI

Storage:
1.Keep it in cool, ventilated place
2.Keep away from heat surface, sparks, open flames and other ignition sources, no smoking. In winter, keep it above 0 ℃ to prevent freezing.
3.Keep container tightly closed.must be kept separate from the oxidant and alkali.
4.Use explosion-proof [electrical/ventilating/lighting]equipment.
5.Use non-sparking tools.
6.Ground and bond container and receiving equipmen.
