Abstract
The process of the invention, using a plurality of passes, divides the crude product of each pass into a part which contains tetramers and higher oligomers and represents the desired product of a pass and at least one further part which contains the major part of the monomers, dimers and trimers and which serves at least in part as part of the starting materials in a subsequent reaction pass. At the same time, the catalyst concentration is increased. In all reaction passes, only a moderate starting material conversion is sought.
