Trimethylolpropane trioleate was synthesized by oleic acid and trimethylolpropane as the raw material, SnCl2·2H2O as catalyst, toluene as watercarrying. The optimum reaction condition obtained through the experiments were found as follows: the molar ratio of OA to TMP was 3.1:1, the amount of SnCl2·2H2O was 2%, with toluene 2ml, reacted for 2h at temperature 170°C and vacuum degree 0.07Mpa. The results...
The effects of zeolite catalysts and reaction conditions on the ring-shift isomerization of sym-OHP into sym-OHA were studied through experiments at 200-300°C under an initial pressure of 0.79 MPa N 2 or H 2 . Eight catalysts were examined, including three hydrogen mordenites, two noble metal loaded mordenites, and three Y-zeolites. Among the three mordenites, the catalyst with lower...
This paper presents our exploratory studies on zeolite-catalyzed conformational isomerization of cis-decahydronaphthalene (cis-DeHN, or cis-decalin) to trans-DeHN at relatively low temperatures. The catalytic reactions were mainly conducted at 473-573 K for 0.15-8 h under an initial pressure of 0.79 MPa N 2 or H 2 using six catalysts: a hydrogen Y zeolite, a lanthanum ion-exchanged...
