Axens' AlphaButol® process developed in cooperation with SABIC is the industry’s benchmark for the production of high purity 1-butene by ethylene dimerization . The process operates in the liquid phase using a soluble catalyst system which avoids isomerization of 1-butene to 2-butene. There is no need for superfractionation of the product stream.

There are now 30 AlphaButol licenses for the production of 1-butene using homogeneous catalysis with a total 1-butene production capacity of 708 000 MTPY.
