Production
UDMH is produced industrially by two routes. One, based on the Raschig process, involves reaction of chloramine with dimethylamine. This method gives the hydrochloride of the hydrazine:
- (CH3)2NH + NH2Cl → (CH3)2NNH2HCl
Alternatively, acetylhydrazine can be N-methylated using formaldehyde to give the N,N-dimethyl-N'-acetylhydrzine, which can subsequently be hydrolyzed:
- (CH3C(O)NHNH2 + 2 CH2O + 2 H2 → (CH3C(O)NHN(CH3)2 + 2 H2O
- (CH3C(O)NHN(CH3)2 + H2O → (CH3CO2H + H2NN(CH3)2

Famous quotes containing the word production:
“The heart of man ever finds a constant succession of passions, so that the destroying and pulling down of one proves generally to be nothing else but the production and the setting up of another.”
—François, Duc De La Rochefoucauld (1613–1680)
“In the production of the necessaries of life Nature is ready enough to assist man.”
