Trimethylolethane (TME) is the
oxidation. More important than TME and closely related is trimethylolpropane
(TMP).
Production
Trimethylolethane is produced via a two step process, starting with the condensation reaction of propionaldehyde with formaldehyde:
- CH3CH2CHO + 2 CH2O → CH3C(CH2OH)2CHO
The second step entails a Cannizzaro reaction:
- CH3C(CH2OH)2CHO + CH2O + NaOH → CH3C(CH2OH)3 + NaO2CH
A few thousand tons are produced annually in this way.[1]
Applications
TME is an intermediate in the production of
heat of fusion 218 kJ/kg. Nitration of trimethylolethane gives trimethylolethane trinitrate, an explosive, monopropellant
, and energetic plasticizer.
