In 1866, the German chemist August Wilhelm von Hofmann proposed a system of hydrocarbon nomenclature in which the suffixes -ane, -ene, -ine, -one, and -une were used to denote the hydrocarbons with 0, 2, 4, 6, and 8 fewer hydrogens than their parent alkane. Some products derived from this group are polyvinyl chloride, trichloroethylene, perchloroethylene, methyl chloroform, polyvinylidene chloride and copolymers, and ethyl bromide. Over 150 million tonnes of ethylene are produced per annum, more than any other organic compound. Even though it has no direct use, being used almost exclusively as a building block, ethylene is largest-volume petrochemical produced worldwide. The Comonomer Production Technology (CPT) can be utilized to produce two valuable comonomers: butene-1 and hexene-1. Steam crackers are large and complex units at the heart of petrochemical complexes, producing the important building blocks ethylene, propylene, butadiene, aromatics and acetylene. However, by that time, the name ethylene was deeply entrenched, and it remains in wide use today, especially in the chemical industry.
