fischer-tropsch catalysts with high activity and selectivity for olefins were produced using mordenite type sio2/al2o3= 12, 20, 28, 62 zeolite supported iron carbonyl compounds and were characterized by x-ray powder diffraction. the adsorptionof volatile fe(co)5 on the support surface was carried out under vacuum at room temperature. reduction les were monitored by vibrating sample magnetometer...
In Fischer-Tropsch synthesis (FTS), a variety of hydrocarbons with different chain lengths are formed. The selectivities depend on the catalyst and reaction conditions. Co-feeding olefins allows changing selectivity even outside rules Anderson-Schulz-Flory distribution. this work, ethene, propene, 1-butene were co-fed to Co-Mn-catalyzed FTS increase olefin in C3- C8-fraction. An CO rate oxygena...
[Co(L)(CO)3]2 (L = CO or PR3) catalyzed hydroformylation of olefins is among the most successful homogeneous organometallic catalysis. The bimetallic complex exists in equilibrium wit...
Stoichiometric reactions of TpRu(CO)(NCMe)(Ph) with electron-rich olefins result in metal-mediated cleavage of C-S and C-O bonds.
Four hydrophobic amino acids (Leu, Tyr, Phe, Trp) were oligomerized by the protease papain in homo-oligomerization, binary co-oligomerization and ternary co-oligomerization. After 24 h, solid polydisperse reaction products of the homo-oligomerization were obtained in yields ranging from 30–80% by weight. A DPavg was calculated based on MALDI-ToF MS results using the ion counts for the chains in...
Supermolecules with olefins organized by hydrogen-bond donor and acceptor templates and that react in the solid state rapidly form co-crystals via solvent-free and liquid-assisted grinding.
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
