Acetonitrile
CAS RN:
75-05-8
PolymerizationA mixture of acetonitrile and sulfuric acid on heating (or self-heating) to 53 deg C underwent an uncontrollable exothermic reaction to 160 deg C in a few seconds. The presence of 28 mol% of sulfur trioxide reduces the initiation temperature to about 15 deg C. Polymerization of the nitrile is suspected. |
