Abstract:
1. A method for producing a high purity terminal olefin, comprising the steps of: (a) contacting a mixture of olefins comprising a terminal olefin and one or more internal olefins, with a brominating agent in the presence of water or an alcohol to form a reaction mixture, whereby said internal olefin(s) are converted into compounds having a higher boiling point than said terminal olefin; and (b) purifying said terminal olefin by distillation from said reaction mixture; wherein said terminal olefin is represented by formula (I): wherein n is an integer of 1 to 6, R represents —CH 2 CH 3 , —CH═CH 2 , —CH 2 CN, or —CH 2 COR 1 , wherein R 1 is selected from the group consisting of hydrogen, alkyl having 1 to 8 carbon atoms, cycloalkyl having 3 to 8 carbon atoms, and alkoxy having 1 to 8 carbon atoms.
