Hexanedioic acid

The leader of DuPont s effort was Wallace H Carothers who reasoned that he could reproduce the properties of silk by constructing a polymer chain held together as is silk by amide bonds The neces sary amide bonds were formed by heating a dicar boxylic acid with a diamine Hexanedioic acid adipic acid) and 1 6 hexanediamme hexamethylenedi-amine) react to give a salt that when heated gives a polyamide called nylon 66 The amide bonds form by a condensation reaction and nylon 66 is an example of a condensation polymer... [Pg.868]

The best known step-growth polymers are the polyamides, or nylons, first prepared by Wallace Carothers at the DuPont Company by heating a diamine with a diacid. Por example, nylon 66 is prepared by reaction of adipic acid (hexanedioic acid) with hexamethylenediamine (.1.,6-hexanediamine) at 280 °C. The designation "66" tells the number of carbon atoms in the diamine (the first 6) and the diacid (the second 6). [Pg.820]

These reactions have not been widely studied however, most authors agree with a lowering of enthalpy or energy of activation. This applies to the system 2-ethylhexanol/ phthalic anhydride226 where AH is 68 kJ mol-1 in the absence of a catalyst and 62 (or 61) kJ mol-1 when H2S04 (or PTS) is added. This is also true for the system 1-octadecanol/octadecanoic acid in octadecyl octadecanoate229 where AH decreases from 50 to 18.5 kJ mol 1 when PTS is added. In the case of the system 1,2-ethanediol/ hexanedioic acid, the decrease is from 50 to 46 kJ - mol-1 when PIS is added313. ... [Pg.84]

Hexanedioic acid is used in the manufacture of nylon-6, 6. Esters of benzoic acid are used in perfumery. Sodium benzoate is used as a food preservative. Higher fatty acids are used for the manufacture of soaps and detergents. [Pg.107]

The reaction of 6-octadecynoic acid (tariric acid) with potassium permanganate yields dodecanoic and 1,6-hexanedioic acid. [Pg.72]

In six male volunteers given 46 mg deuterium-labelled di(2-ethylhexyl) adipate [approx. 0.5 mg/kg bw] in com oil, 2-ethylhexanoic acid was the only metabolite that could be determined in the plasma. It had an elimination half-life of 1.65 h. In urine, the following metabolites were identified (percentage fraction of administered deuterium label) 2-ethylhexanoic acid (8.6%), 2-ethyl-5-hydroxyhexanoic acid (2.6%), 2-ethyl-1,6-hexanedioic acid (0.7%), 2-ethyl-5-ketohexanoic acid (0.2%) and 2-ethylhexanol (0.1%). The half-life for elimination of all metabolites excreted in the urine averaged 1.5 h, and none of the metabolites could be detected after 36 h (Loftus et al, 1993). [Pg.157]
