PHYSICAL AITD CHEMICAL PROPERTIES 
Chlordane is a viscous, amber colored, nearly odorless liquid, "boil- 
ing at 175° C. at 2 mm. pressure. It is insoluble in water and soluble 
in organic solvents such as aliphatic, aromatic, and chlorinated hydro- 
carbons, as well as in ketones, esters, and ethers. It is completely 
mi6cible in all proportions with deodorized kerosene, a solvent widely 
used for insecticidal products. — Kearns ejt al. ( 2^5 ,); Sun ( 446 ): Vest 
(496). Its specific gravity range is 1.60-1.635 at 60° F./60° F., 
equivalent to a weight per gallon of approximately 13*3-13.6 pounds. 
The refractive index is 1.56-1.57 at 25° C— Bussart and Schor (j&) . 
It has been reported that Van Dyk 264 (N-octyl-bicyclo[2.2.l]-5- 
heptene-2,3-dicarboximide) , a synergist for pyrethrins, will dissolve 
50 percent of its weight of chlordane. — Anon. Q) . 
Chlordane dehydrohalogenates in the presence of alkaline reagents 
with concomitant loss of insecticidal activity. For this reason, it 
should not be formulated with alkaline solvents, carriers, or emulsifiers.

issues of the American Fruit Grower. Chlordane is represented as doubt-
