Dodecane diamine

The second known azaisowurtzitane, the tetraazaisowurtzitane 2,6,-eih-ylene-8,12-ethylene-4,10-dioxa-2,6,8,12-tetraazatetracyclof5.5.0.0 . 0 j dodecane (2,6-ethylene-8,12-ethylene-4, lO-dioxa-2,6, S, 12-tetraazaiso-wurtzitane, 46) was reported by Edwards and Weiss in 196S (Ref. 96). It was obtained in 20% yield by condensation of glyoxal with ethylene-diamine in dilute aqueous solution buffered to pH 9 with Na HP04. 

Hexamethylene diamine can be produced by various processes (see also Chapter 24), and is industrially mostly produced from adipic acid, butadiene, or acrylonitrile. Sebacic acid is obtained from castor oil. Because of the uncertain supply situation, the sebacic acid for such polyamides is being increasingly replaced by dodecane diacid, which is obtained by the oxidation of cyclododecatriene, the cyclic trimer of butadiene. The monomers for polyamide 13,13 are derived from erucic acid (see also Chapter 24).
