THE γ-RAY RADIOLYSIS OF METHYL SUBSTITUTED BORAZOLES1

Abstract

The 100 ev yields of hydrogen, methane, and ethane from the cobalt-60 gamma -ray radiolysis of N-trimethyl-, B-trimethyl-, and hexamethylborazole are independent of dose and dose rate. At 30 deg , the hydrogen, methane, and ethane yields are, respectively, 3.53, 0.015, and <0.01 for N-trimethylborazole; 1.65, 1.38, and 0.08 for B-trimethylborazole; and the predominant product at -196 and -- 78 deg . Between --6 and 100 deg the methane yields from irradiated hexamethyl- and B-trimethylborazole change more with temperature than the corresponding hydrogen and ethane yields. Above 100 deg , however, the methane yields vary only slightly with temperature. The methane yield from N-trimethylborazole is low regardless of irradiation temperature.
