Tris(hydroxymethyl)nitromethane synthesis

9synthesis methods
Tris(hydroxymethyl)nitromethane is prepared by the condensation of nitromethane and formaldehyde under basic conditions.
-

Yield:-

Reaction Conditions:

with triethylamine at 45 - 50; for 1 h;

Steps:

2
Conversion of nitromethane (NM) to tris(hydroxymethyl)nitromethane (TN).5 equivalents of methyl formcel are charged to the reaction flask. The reaction is catalyzed with 0.4 mole % triethylamine (TEA), which is added to the methyl formcel. NM (1.0 molar eq.) is fed into this mixture at such a rate so as to keep the temperature between 45 - 50°C. Once the NM has been added, the reaction mixture is stirred for an additional hour. During this time, no external cooling is applied and the temperature will drop slowly.
