실험 절차
Vernolia oil undergoes saponification and acification followed by cold temperature (-20° C.) crystallization to yield a methylated product comprised of vernolic, palmitic, oleic, linoleic and stearic acid. The vernolic acid is isolated and further purified through a series of low temperature recrystalizations. The purified vernolic acid, ##STR1## is then hydrogenated to yield 12,13-epoxystearic acid, having the formula: ##STR2## The 12,13-epoxystearic acid is then oxidized to yield 12-oxododecanoic acid, ##STR3## By reacting the 12-oxododecanoic acid with hydroxylamine, 12-oxododecanoic acid oxime ##STR4## is formed. The Nylon-12 monomer, 12-aminododecanoic acid:
