Mothball differentiation: naphthalene from paradichlorobenzene.

Abstract:

:In order to develop a rapid, simple test to differentiate toxic naphthalene from the less toxic mothball ingredient paradichlorobenzene, both types of mothballs were dissolved in isopropyl alcohol, ethanol, methanol, and turpentine. Twenty-five naphthalene and 25 paradichlorobenzene mothballs were weighed, randomly grouped, and then dissolved in the solvents. After 30 minutes, the mothballs were reweighed. Isopropyl alcohol, ethanol, and methanol did not differentially dissolve the mothballs fast enough to provide a useful test. Turpentine, however, dissolved paradichlorobenzene at a much more rapid rate than naphthalene (P less than .001). After 60 minutes, all of the paradichlorobenzene mothballs had dissolved, while at least 25% of the naphthalene remained. Thus, when confronted with an ingestion of unlabeled mothballs, the physician could gain preliminary information regarding possible toxicity by dissolving a remaining mothball in turpentine for 60 minutes.
