,Summary — Directions for the Future,opylene, butenes and butadiene and the aromatics benzene, toluene and xylenes constitute the key base chemicals in this industry. This dependence on a single raw material for both liquid fuels and chemicals places the chemical industry in an extremely vulnerable position. This vulnerability has beco
