The influences of temperature, pressure, catalyst content, H2O2 content and mol ratio of propylene to H2O2 on epoxidation of propylene with H2O2 over TS-1 in a
Ethanol has more accessible critical properties (Tc = 241℃, Pc =6.38 MPa) than water and stronger solubility power than carbon dioxide. Nearcritical and superc
Colloidal gas aphrons(CGAs) were first defined by Sebba(J.Colloid Interface Sci.,1971,35(4):643) as micro bubbles(25—300*μm).These microbubbles do not coalesce
