Relative retention times of chlorinated monoterpenes

GC retention times for 67 chlorinated monoterpenes. belonging to the techni cal pesticide Toxaphene have been measured under the same conditions and re lative retention times have been determined. They consisted of 45 chlorinat ed bornanes, 13 chlorinated bornenes, 8 chlorinated dihydrocamphenes and 1 chlorinated camphene. Useful correlations between structure and retention t ime were found. Similar changes in structure for different compounds lead t o similar changes in retention times. These correlations allow to predict r etention times for yet unknown Toxaphene congeners.
