Docosanedioic acid

C. Docosanedioic acid. All the crude disodium 7,16-diketodocosanedioate of Step B is added to 11. of triethanolamine in a 5-1. round-bottomed flask equipped with a reflux condenser, a thermometer, a mechanical stirrer, and a deep oil bath. The mixture is heated under reflux until all the salt dissolves (about 15 min-... [Pg.35]

Very pure docosanedioic acid can be obtained by another recrystallization from about 450 ml. of 2-methoxyethanol. The recrystallized acid is collected on a Buchner funnel, and the well-pressed filter cake is suspended in 200 ml. of 95% ethanol, refiltered, and dried in air weight 112 g. (61%) m.p. 126-127° neutralization equivalent, 185-187. [Pg.38]

The checkers found it slightly more convenient to recrystallize the moist crude docosanedioic acid from 1 1. of methyl ethyl ketone. The hot solution is filtered and cooled, and the acid is collected on a Buchner funnel, washed with methyl ethyl ketone, and dried in air. [Pg.38]

Docosanedioic acid has been prepared by Wolff-Kishner reduction of 6,17-diketodocosanedioic acid, formed by reaction of the half-ester acid chloride of adipic acid with the a,co-cadmium derivative of decane (%26 overall yield).3 Reduction of Wolff-Kishner method, followed by simultaneous reduction and desulfurization with Raney nickel of the 2,5-bis(co-carboxyoctyl)thiophene pro-... [Pg.38]

The present method of making docosanedioic acid has been described by Hiinig and Liicke. The Wolff-Kishner reduction of the diketonic intermediate is am application of the modification of Gardner, Rand, and Haynes. ... [Pg.39]

In the present volume, easily three-fourths of the preparations fall into this class. Thus the preparation of docosanedioic acid (p. 34) demonstrates how acylation of an enamine can be used to prepare long-chain acids. The preparation of N-nitromorpholine... [Pg.128]

This triethanolamine procedure was used also in a synthesis of docosanedioiC acid starting with the condensation of cyclohexanone with morpholine to form 1 morpholino-1-cyclohexene (1), and acylation of this enamine with sebacoyl chlorid ... [Pg.222]
