Thermoregulated organic biphasic system composed of triethylene glycol monomethylether (TGME) and n-heptane was first applied to the hydrogenation of 1-octene. Under theoptimal conditions: P(H2)=5.0MPa, T=80℃, t=3h, 1-octene/Ru=1000 (molar ratio), the yield ofn-octane reached up to 99.6%. Furthermore, the simply decanted catalyst could be reused for 10times without apparent loss of catalytic activity.
Colloidal dispersion of nano-Ru/SiO2 in PEG (polyethylene glycol, M.W.=400) was used for benzene hydrogenation. The system has the features of easy catalyst’s recycling and high catalyst stability.
