Efficient conversion of ethanol to 1-butanol and C₅-C₉ alcohols over calcium carbide.

ABSTRACT: Production of 1-butanol or alcohols with 4-9 carbon atoms (C₄-C₉ alcohols) from widely available bio-ethanol has attracted much interest in recent years in academia and industry of renewable chemicals and liquid fuels. This work discloses for the first time that calcium carbide (CaC₂) has a superior catalytic activity in condensation of ethanol to C₄-C₉ alcohols at 275-300 °C. The 1-butanol yield reached up to 24.5% with ethanol conversion of 62.4% at the optimized conditions. The by-products are mainly alcohols with 5-9 carbons besides 2-butanol, and the total yield of all the alcohols reached up to 56.3%. The reaction route was investigated through controlled experiments and quantitative analysis of the products. Results indicated th
