Chevron Phillips Chemical produces 99% cyclohexane at its chemical complex at Port Arthur, Texas and affiliated chemical complex at Al Jubail, Saudi Arabia. Chevron Phillips Chemical is also the exclusive marketer of ConocoPhillips’ 99% cyclohexane produced at its 100-million-gallon Sweeny, Texas unit. Chevron Phillips Chemical's capacities are shown below. How It's Made All cyclohexane is produced in benzene hydrogenation units. In the process, high-purity benzene feed and purified hydrogen (typically recovered from reformers and ethylene crackers) are brought to reaction temperatures and charged to the reactor. The conversion of benzene to cyclohexane is stoichiometric and almost complete; finished cyclohexane typically contains less than 25 ppm of benzene. A small amount of lower purity cyclohexane is recovered from petroleum streams by fractionation and extraction. Over 90% of the cyclohexane production is used to produce intermediates for nylon 6 and nylon 66. Nylon 6 is made by polymerizing caprolactam which is derived from the nitration of cyclohexane. Nylon 66 is made by polymerizing equal molar quantities of adipic acid and hexamethylene diamine (HMDA). Adipic acid is made by a two-step air and nitric acid oxidation of cyclohexane. The adipic acid is converted to HMDA by the reduction of adiponitrile (an intermediate). Adipic acid produced from cyclohexane is also used to manufacture esters for plasticizers and synthetic lubricants, as well as produce polyeurethanes (synthetic leather). How It's TransportedChevron Phillips Chemical transports cyclohexane via ships, barge, truck and rail.  What It's Used For
Most cyclohexane goes into the production of intermediates for nylon, which has a variety of common applications such as clothing, tents and carpets as well as thermoplastics. Cyclohexane is also used as a solvent in chemical and industrial processes and recently has been substituted for benzene in many applications. Chevron Phillips Chemical also offers other solvents through our Specialty Chemicals Division. Technical Literature Contacts Ron Nemcheck |
