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:
“Constant revolutionizing of production ... distinguish the bourgeois epoch from all earlier ones. All fixed, fast-frozen relations, with their train of ancient and venerable prejudices are swept away, all new-formed ones become antiquated before they can ossify. All that is solid melts into air, all that is holy is profaned, and man is at last compelled to face with sober senses, his real conditions of life, and his relations with his kind.”
—Karl Marx (1818–1883)
“Just as modern mass production requires the standardization of commodities, so the social process requires standardization of man, and this standardization is called equality.”
—Erich Fromm (1900–1980)
“It is part of the educator’s responsibility to see equally to two things: First, that the problem grows out of the conditions of the experience being had in the present, and that it is within the range of the capacity of students; and, secondly, that it is such that it arouses in the learner an active quest for information and for production of new ideas. The new facts and new ideas thus obtained become the ground for further experiences in which new problems are presented.”
—John Dewey (1859–1952)
