摘要: Processes for producing a linear internal olefin product include the steps of contacting an olefin feed containing C10-C20 vinylidenes and a C10-C20 normal alpha olefin and/or C10-C20 linear internal olefins, a first acid catalyst, and a C1 to C18 carboxylic acid to form a first reaction product containing linear internal olefins, trisubstituted olefins, and secondary esters, then removing all or a portion of the secondary esters from the first reaction product, followed by contacting the secondary esters and a second acid catalyst to form a second reaction product comprising linear internal olefins, and then removing all or a portion of the linear internal olefins from the second reaction product to form the linear internal olefin product. Linear alkanes subsequently can be produced by hydrogenating the linear internal olefin product to form a linear alkane product.

摘要: Processes and reaction systems for olefin metathesis by reactive distillation, utilizing liquid phase metathesis of reactant olefins in the presence of a homogeneous metathesis catalyst system, where the light metathesis product is produced and leaves the liquid phase as vapor phase and the heavy metathesis product is produced in liquid phase. Separation can be performed on the light metathesis product and a distinct other separation can be performed on the heavy metathesis product.

摘要: Processes for producing n-heptane from a mixture of 1-hexene and 1-octene in the presence of a suitable isomerization-metathesis catalyst followed by a hydrogenation step are disclosed. Integrated manufacturing systems for producing n-heptane with minimal waste also are disclosed.
