Disclosed is a process for preparing C.sub.5 to C.sub.18 straight chain .alpha.-olefins from the corresponding internal olefins. The process comprises reacting a C.sub.5 to C.sub.18 straight chain olefin reactant with an electrophilic compound containing hydrogen followed by selectively cracking the resulting product.

Process for selectively producing C5 to C18 straight chain .alpha.

Disclosed is a process for preparing 1-hexene from 1-butene. The 1-butene is metathesized to produce 3-hexene which is then subjected to, e.g., an hydration/dehydration procedure to produce a mixture of n-hexenes containing 1-hexene.

Stable substituted succinic anhydride/ether-ester emulsifier composition

A stable composition comprising a hydrocarbyl-substituted succinic anhydride and a polyethylene glycol diester emulsifier. There is also disclosed a method for imparting water repellency to surfaces containing groups reactive to anhydrides and a method for the sizing of paper using said composition.

Substituted succinic anhydride/emulsifier composition

A process for purifying predominantly straight chain olefins having from 5 to 50 carbon atoms which comprises contacting the olefins with a liquid solution of boron trifluoride in an alcohol or mixture of alcohols.
