    (a) Adipic acid (C6H10O4, CAS Reg. 
No. 00124-04-9) is also known as 1,4-butanedicarboxylic acid or hexane-
dioic acid. It is prepared by nitric acid oxidation of cyclohexanol or 
cyclohexanone or a mixture of the two.

The melting range of the amide is 219[deg] to 220 [deg]C.
    (2) The adipic acid is converted to its corresponding bis-p-p-
