Bioethanol valorization to butanol by continuous heterogeneous catalytic self-alkylation provides an option for the fuel industry. Dimerization of ethanol (E) was studied over activated carbon supported metal loaded and metal-free alkaline catalysts using a flow-through tube microreactor, applying WHSVE of 0.20-2.0 gE/h gcat. , 21 bar total pressure and 275-400°C reaction temperature. Activated carbon (AC) was impregnated with various alkaline salts as the catalysts of the aldol reaction. Different basicity of the investigated catalysts resulted in differing catalytic activities. Butanol was the product of highest yield. Longer chain primary aliphatic alcohols, having even number of carbon atoms were also obtained with yield decreasing significantly with increasing chain length.

Abstract[Zn6(L)4(DMF)2(H2O)4](1,4-Dioxane)2(DMF)10(H2O)4 (1, L  =  4,4′,4″-(benzene-1,3,5-triyltris(oxy))tribenzoate), the metal-organic cage, was produced via Zn(NO3)2·6H2O reacting with the H3L ligand in the mixed solvent of DMF and water. The heterogeneous catalytic activities of the complex 1 for the aldehydes cyanidation under the conditions of free solvent were studied, which indicates that the removal of coordination solvents could greatly improve the catalytic activities. Furthermore, the inhibitory effect of the compound against the ovarian cancer cells was assessed. The mi-RNA16 relative expression level was measured after exposure to the compound with real-time reverse transcription-polymerase chain reaction. The invasion and migration of cells after compound treatment were also detected by the transwell method.
