ABSTRACT:
Aluminoxane is made by feeding water, hydrocarbylaluminum and organic solvent to a loop recycle reactor under conditions so as to react the water and hydrocarbylaluminum to form a hydrocarbylaluminoxane, removing a portion of the solvent and hydrocarbylaluminoxane from said reactor and recirculating the remaining portion of the reactor contents through a reaction zone where the water initially contacts the hydrocarbylaluminum. The feed rates of water, hydrocarbylaluminum and solvent to the reactor and the withdrawal rate of solvent and hydrocarbylaluminoxane from the reactor can be adjusted to produce a substantially steady state reaction.
