NOVELTY - Ambient pressure non-oxidative catalytic chemical combination comprises a polar organic reactant (a1) in a liquid range in combination with another organic reactant (b1) to form products (c1) by condensation in absence of air. The reactant (a1) is e.g. alcohol, glycol or ether. The reactant (b1) is e.g. alcohol, glycol, ether, alkane or alkene. The products (c1) are higher molecular weight alcohol, glycol, ether, alkane, alkene, aldehyde, ketone, carboxylic acid, ester, amine, imine, thiol, sulfide, phosphine or related organic compound.    USE - For non-oxidative chemical conversion of liquid alcohols to higher boiling alcohols, ethers, glycol ethers, amines and oxygenated gasoline products comprising ethanol to butanol, propanols to hexanols, butanols to octanols, ethanol plus butanol to ethyl butyl ethers, ethanol plus ethyl butyl ethers to ethyl hexyl ethers as oxygenated gasoline, ethanol plus ethyl hexyl ethers to butyl hexyl ethers as oxygenated gasoline, n-butyl amine plus ethanol to ethyl butyl amine, hexyl amines and related products (claimed).    ADVANTAGE - The liquid reactants are catalytically converted to higher molecular weight products at ambient pressure in the absence of air and at reflux temperatures. This combination provides efficient catalytic conversion of chemical compounds produced from renewable resources including liquid ethanol and/or other available compounds to higher boiling alcohols, ethers, glycol ethers, oxygenated gasoline, oils, polymers or other products in the absence of air at reflux temperatures employing catalysts based on transition metal complexes of low valence possessing a degree of symmetry. The catalysts are effective for non-oxidative catalytic conversion of substituted organic compounds to products comprising related higher molecular weight compounds in good yields in the absence of air, at modest temperatures and pressures. The catalytic conversion is carried out without addition of aggressive chemical oxidizing agents and without addition of other strong chemicals.    DETAILED DESCRIPTION - Ambient pressure non-oxidative catalytic chemical combination comprises a polar organic reactant (a1) in a liquid range in combination with another organic reactant (b1) to form products (c1) by condensation in absence of air.
