How is ethylbenzene produced
WebYou can smell ethylbenzene in the air at 2 parts of ethylbenzene per million parts of air (2 ppm). It evaporates at room temperature and burns easily. Used in industry and in consumer products Ethylbenzene is found naturally in oil. Large amounts of ethylbenzene are produced in the United States; most of it is used to make styrene. Web4 mrt. 2024 · The current industrial route to making styrene from ethylbenzene has a typical single-pass yield of 54%. It requires high temperatures as well as steam, which provides heat and pushes the reaction’s equilibrium toward styrene. The process developed by Li’s team has a 91% yield.
