Abstract

Sulfolane is a useful industrial solvent. The oral LD₅₀ values were: rats, 1·7 to 2·7 g./kg.; mice, 1·9 to 2·5 g./kg., all deaths taking place within 24 hours. Rats showed no effects after 3·8 g./kg. had been applied to the skin. The compound did not irritate or sensitize the skins of guinea-pigs or rabbits and, undiluted, was almost without action on the eyes of rabbits.
