N-Butyl borate

Tri-n-butyl borate [688-74-4] M 230.2, b 232.4°, n 1.4092, d 0.857. The chief impurities are n-butyl alcohol and boric acid (from hydrolysis). It must be handled in a dry-box, and can readily be purified by fractional distillation, under reduced pressure. 

One of the experimental limitations on the electron donor is that it must not catalyze the hydrolysis of the RBAX. It cannot, therefore, be a highly basic amine. We have chosen, therefore, to study the photoreduction of RBAX in the presence of a soluble nonhydrolytic donor, triphenyl n-butyl borate. 

Irradiation of RBAX (1.19 x 10-4 M) in the presence of triphenyl n-butyl borate ion (1.89xlO 3M) results in the bleaching of RBAX and the...
