ABSTRACT:
A new scintillator composition, consisting essentially of di-m-methylphenyl-1,3,4-oxadiazole, or 2,5-di-m-tolyl-1,3,4-oxadiazole, is prepared by reacting m-toluoyl chloride with hydrazine to form di-m-toluoyl hydrazine which, in turn, is reacted with thionyl chloride to form the desired product which is dissolved in an organic solvent. The scintillator, di-m-methylphenyloxadiazole compares favorably with present commercial products, being equal to or better than diphenyloxazole in most important respects and significantly superior in scintillation pulse height and in stability. It can be produced at a fraction of the cost of today's most widely used product.
