Isomerization of phenols from a coal tar fraction

Akhmetkarimova, Zh.S.; Baikenov, M.I.; Meiramov, M.G.; Feng-yun, Ma. (ALLERTON PRESS INC, 2014-05)

A new method for the hydrogenation of a primary coal tar fraction in the presence of a nanocatalyst at an elevated pressure in an atmosphere of hydrogen was proposed. The effect of the relative H-donor ability of the primary ...
