Cracked naphtha
Webnaphtha: [noun] any of various volatile often flammable liquid hydrocarbon mixtures used chiefly as solvents and diluents. Modern high-pressure thermal cracking operates at absolute pressures of about 7,000 kPa. An overall process of disproportionation can be observed, where "light", hydrogen-rich products are formed at the expense of heavier molecules which condense and are depleted of hydrogen. The actual reaction is known as homolytic fission and produces alkenes, which are the basis for the economical…
