Abstract

PESTAB. Details of high performance liquid chromatographic analysis of the heptachloro naphthalenes present in Halowax 1051 are presented. The NMR evidence, as well as the HPLC and UV data, strongly suggest that the heptachloro naphthalene isomer prepared by the reduction of octachloro naphthalene is the 1H-isomer, and that obtained by crystallization from Halowax 1051 is the 2H-isomer. Preparative-scale HPLC may be useful for studying the isolation of pure 1H- and/or 2H-heptachloro naphthalene. Reversed-phase HPLC has good potential for separating highly chlorinated compounds and surpasses HPLC in the system silica gel:dry n-hexane in this respect.
