Interesterification optimization of waste cooking oil and ethyl acetate over homogeneous catalyst for biofuel production with engine validation

Applied Energy, 2018
The interesterification of waste cooking oil (WCO) and ethyl acetate (ETA) are investigated in homogeneous catalyst system using sodium hydroxide (NaOH) and acetic acid (CH3COOH).

Heterogenization of homogeneous catalysts

Journal of Molecular Catalysis, 1986
The surface reactions which take place when TiCl4 is reacted with -AlEtCl or -AlEt2 on a silica surface have been studied by EPR and chemical analysis. These systems have been compared to the reverse reactions, when -TiCl3 anchored to the silica surface is reacted with Et2AlCl or Et3Al.

Homogeneous catalysts to solid catalysts

Current Opinion in Solid State and Materials Science, 1996
Abstract Recent advances have been made in the transformation of homogeneous to solid catalysts. They include the use of metal complexes immobilized on organic and inorganic supports, solid acids and bases, redox molecular sieves as solid catalysts for liquid phase oxidations, zeolite-encapsulated metal complexes and supported liquid phase catalysts.

Modular Homogeneous Chromophore–Catalyst Assemblies

Accounts of Chemical Research, 2016
Photosynthetic reaction center (RC) proteins convert incident solar energy to chemical energy through a network of molecular cofactors which have been evolutionarily tuned to couple efficient light-harvesting, directional electron transfer, and long-lived charge separation with secondary reaction sequences. These molecular cofactors are embedded within

Polymer Fibers as Carriers for Homogeneous Catalysts

Chemistry – A European Journal, 2007
AbstractThis paper describes a polymer fiber‐based approach for the immobilization of homogeneous catalysts. The goal is to generate products that are free of catalysts which would be of great importance for the development of optoelectronic or pharmaceutical compounds.

A Chromium Catalyst for the Polymerization of Ethylene as a Homogeneous Model for the Phillips Catalyst

Journal of the American Chemical Society, 2005
A structurally characterized cationic chromium(III) alkyl featuring a bulky nacnac ligand catalyzes the polymerization of ethylene as well as the copolymerization of ethylene with alpha-olefins. This well-characterized homogeneous catalyst constitutes a structural as well as functional model of the widely used heterogeneous Phillips olefin ...
