Synthesis and Characterization of Tri(Hydroxymethyl)Nitromethane

Tris hydroxymethyl nitromethane synthesis

The bases are generally alkali or alkaline earth hydroxides, basic ion exchange resins or tertiary amines. All the processes are used in an aqueous or water-alcohol medium. After formylation and elimination of the base, reduction is performed under hydrogen pressure, at times in the presence of carbon dioxide to reduce secondary reactions; there then follow the operations. The amount of hydrogenation catalyst is selected so that it represents 5 to 25 by weight of the nitroalcohol to be reduced. After hydrogenation, the reaction medium is filtered to eliminate the catalyst, and is cooled to Dec 25, 2015. SUMMARY OF THE INVENTION. An improved process has been found that makes it possible to obtain very pure crystallized tris(hydroxymetyl)aminomethane with a yield on the order of 80, the total yield being greater than 90.

The product formed in the formylation phase is acidified by a concentrated acid to a pH between 2.7 and 7, preferably between 4.5 and 5.5. The nitroalcohol thus obtained is diluted in methanol containing 2 to 5 methylene chloride, preferably 2.5; it is then hydrogenated with hydrogen to the exclusion of any other gaseous constituent under a.

Tris hydroxymethyl nitromethane synthesis
According to the invention, the tris(hydroxymethy)aminoethane is prepared in a concentrated alcohol medium by the action of polyoxmethylene on nitromethane in the presence of a catalytic amount of a solid alkaline agent and methylene chloride; followed by an acidification and reduction by hydrogen in an alcohol medium containing methylene chloride.
