1.6- hexanedicarboxylic acid

The ozonolysis of cyclohexene to 1,6-dioxygenated compounds is shown in Figure 17.28. Other cycloalkenes similarly afford other l,y-dioxygenated cleavage products. With the three methods for workup (Figure 17.27), this ozonolysis provides access to 1,6-hexanediol, 1,6-hexanedial, or to 1,6-hexanedicarboxylic acid. Each of these compounds contains two functional groups of the same kind. [Pg.770]

A representation of an intramolecular Claisen-type condensation (an acyloin condensation) in which the diethyl ester of 1,6-hexanedicarboxylic acid (diethyl adipate, CH3CH202C(CH2)4C02CH2CH3)) undergoes cychzation to yield ethyl 2-oxocyclopentanecarboxylate in the presence of ethoxide anion ( OCH2CH3) in ethanol (ethyl alcohol, CH3CH2OH) solvent.

The main raw material for the production of polyamide 66 is an aqueous solution of the organic salt obtained by the reaction of 1.6 hexamethylenediamine and 1.6 hexanedicarboxylic acid (adipic acid), also called AH salt, 66 salt or nylon salt. [Pg.142]

There are relatively few entries in the non-fused dioxepin area, and most of these focus on reactions of these systems. For example the triflic acid-initiated polymerisation of 1,3-dioxepane in the presence of acetic acid and hexanedicarboxylic acid has been studied and mechanistic aspects discussed <00JPS(A)1232>. Biodegradable microspheres for the controlled delivery of drugs have been made from copolymers and homopolymer blends of L-lactide and l,5-dioxepan-2-one <00PP1628>. Ring contraction of 5-methylene-l,3-dioxepanes (eg. Ill) on reaction with trimethylsilyl trifluoromethanesulfonate in the presence of base afforded the exo tetrahydropyrans, in good yields <00TL2171>. [Pg.362]
