Abstract
Improved methods of preparation are reported for the following isomerically pure polychloronaphthalenes: 1,2,3,4,5,6,7- and 1,2,3,4,5,6,8-heptachloro; 1,2,3,4,5,6-, 2,3,4,5,6,7-, and 1,2,4,6,6,7-hexachloro; 2,3,4,5,6-pentachloro; plus the mixtures of 1,2,3,4,6,7- and 1,2,3,5,6,7-hexachloro isomers. Sufficient quantities of these environmentally ubiquitous materials have been obtained so that for the first time complete physicochemical data are presented that unambiguously characterize these compounds. Also included is an X-ray crystallographic analysis of 2,3,4,5,6,7-herachloronaphthalene which crystallized in the space group P12121 with cell dimensions: a=11.2187 (13), b=14.7768 (22), and c=6.898 (3)
