Apr 23, 2002 · It was found that 20% w/w DTP/K-10 clay offered the best conversion with favourable product distribution. A molar ratio of 10:1 benzene/1-dodecene favoured the formation of linear dodecylbenzenes (LAB). However, with decreasing benzene concentration, the formation of didodecylbenzenes increased. The best parameters for the alkylation were ... Walter Reppe developed a process for the "safe" trimerization of acetylene to benzene and cyclooctatetraene. Although completely superseded by more modern alternatives, this process was used before/during WW2 because starting from only coal, calcium carbonate and electricity one could synthetise calcium acetylide and therefore acetylene, having no need for oil derivatives, scarce during war.
