| titleOfInvention | Method for producing styrene |
| abstract | PROBLEM TO BE SOLVED: To produce styrene with a high yield and a high selectivity by suppressing the generation of heavy components in the dehydration reaction of α-phenylethyl alcohol and maintaining a high conversion. Provide a way. SOLUTION: A method for producing styrene, comprising steps 1 to 4. 1) Dehydration step: in the liquid phase, in the presence of an organic sulfonic acid, α- Step 2) Dehydration of phenylethyl alcohol to obtain styrene 2) Separation step of styrene: Step 1 of separating the reaction liquid after step 1 into a component mainly containing styrene and a component containing phenylethyl alcohol 3) Recycling step: Obtained in two steps Step of recycling the component containing phenylethyl alcohol to the dehydration step 4) Separation step of β-phenylethyl alcohol: β-phenylethyl alcohol is removed from the reaction solution two steps before and two steps after the step, or β-phenylethyl alcohol, and α-phenyl Step of obtaining a component containing ethyl alcohol and supplying the component to two or one step |
