Methods for suppressing isomerization of olefin metathesis products |
| 摘要 |
A method for suppressing isomerization of an olefin metathesis product produced in a metathesis reaction includes adding an isomerization suppression agent to a mixture that includes the olefin metathesis product and residual metathesis catalyst from the metathesis reaction under conditions that are sufficient to passivate at least a portion of the residual metathesis catalyst. The isomerization suppression agent includes (i) a salt and/or an ester of a phosphorous oxo acid, and/or (ii) a derivative of the phosphorous oxo acid in which at least one P—H bond has been replaced by a P—C bond, and/or (iii) a salt and/or an ester of the derivative. Methods of refining natural oils are described. |

1. A method for suppressing isomerization of an olefin metathesis product, the method comprising:
providing a mixture comprising an olefin metathesis product and residual metathesis catalyst; and adding an isomerization suppression agent to the mixture to passivate at least a portion of the residual metathesis catalyst; wherein the isomerization suppression agent is a phosphite ester. |
