Furfural reaction with 1,3-butadiene

A new commercial use for butadiene is its employment in the nylon synthesis joining furfural, benzene, and cyclohexane as raw materials for nylon salt components. Amother olefinic hydrocarbon, which has found large scale application in recent years, is propylene tetramer, widely employed in reaction with aromatic nuclei to yield an alkylated aromatic base used in synthetic detergent production. 

As all pyrolysis reactions, the decomposition of furfural to furan and carbon monoxide is accompanied by other minor reactions. Of the gases formed, only 80 percent is carbon monoxide, other gases identified being 10 percent hydrogen as well as small quantities of carbon dioxide, butadiene, propadiene, ethylene, propylene, acetylene, methylacetylene, and cyclopropene. As the quantities of carbon dioxide and butadiene are roughly equal on a molar basis, it is believed that a part of the furfural reacts with pyrolytically liberated hydrogen ...
