Abstract
A method of producing an internal olefin, including the step 1 and the step 2 below in this order. Step 1: a step of isomerizing a raw material olefin having 8 or more and 36 or less carbon atoms to provide an internal olefin containing a 1-olefin Step 2: a step of isomerizing the 1-olefin contained in the internal olefin provided in the step 1 at a temperature that is lower than the reaction temperature in the step 1.
Claims16
A method of producing an internal olefin, comprising a step 1 and a step 2 in this order:
- step 1:
- a step of isomerizing a raw material olefin having 8 or more and 36 or less carbon atoms to provide a mixture containing an internal olefin and a 1-olefin;
- and
- step 2:
- a step of isomerizing the 1-olefin contained in the mixture provided in the step 1 at a temperature that is lower than a reaction temperature in the step 1;
- wherein an average double bond position of the internal olefin after completing an isomerization reaction in the step 1 is more inner than an average double bond position of the raw material olefin.
