Production and thermal neutron irradiation of tri-alkylborance, (2)

Tri-iso-butylborane was synthesized from organometallic compound (alkylaluminum) and boron trifluoride. The compound was irradiated under the thermal neutron flux of UTR-Kinki with comparatively lower dose (1.57 - 5.99 x 1012n/cm2) and investigated the changes of the compound. The products were examined by means of GC and GC-MS method. Hydrogen, iso-butane, 2,5-dimethylhexane and diisobutyl-2,2,4-trimethylpentylborane were recognized. Diisobutylether that was considered the oxidized compound formed from the action of impurity of oxygen was also recognized. Formation of these compounds, except diisobutylether, could be explain by radical-radical reaction, dimerization and hydrogen atom abstraction of radicals. (author)
