Title:

METHOD FOR PREPARING POLYBUTENE BY USING CATALYST CONTAINING N-PROPANOL

Document Type and Number:

WIPO Patent Application WO/2015/194874

Kind Code:

A1

Abstract:

Disclosed is a method for preparing a polybutene by using a catalyst containing n-propanol, wherein the content of vinylidene is 40-70%, the content of a tetrasubstituted double bond is 10% or more, and a complex catalyst containing n-propanol, which is a cocatalyst, and a main catalyst such as boron trifluoride is used. The method for preparing a polybutene by using a catalyst containing n-propanol comprises the steps of: injecting, into a reaction material containing 10 wt% or more of isobutene, a complex catalyst comprising n-propanol as a cocatalyst and boron trifluoride as a main catalyst; and polymerizing the reaction material at a reaction temperature of -33 to 33°C and a reaction pressure of 3-50 kg/cm2, wherein the content of vinylidene is controlled by controlling the reaction temperature.
