摘要： Aluminoxane is made by feeding water, hydrocarbylaluminum and organic solvent to a loop recyle 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.

摘要： Water, hydrocarbylaluminum (e.g., trimethylaluminum), and organic solvent (e.g., toluene) are fed to a reactor in controlled proportions and under temperature control to form a dilute reaction product mixture of specified composition and concentration. This solution is then processed so as to form at least two product mixtures, one of which is essentially aluminoxane-free hydrocarbylaluminum dissolved in organic solvent, and another of which is a concentrated solution of organoaluminum compounds composed in essence of hydrocarbylaluminum and hydrocarbylaluminoxane in organic solvent in which the amount aluminoxane far exceeds the amount of hydrocarbylaluminum. It is advantageous to add the water to a solvent solution of a hydrocarbylaluminum compound and/or an aluminoxane by feeding the water through an orifice which is surrounded by a flow of solvent which carries the water into the solvent solution of hydrocarbylaluminum compound and/or aluminoxane.
摘要翻译：将水，烃基铝（例如三甲基铝）和有机溶剂（例如甲苯）以受控的比例并在温度控制下加入到反应器中以形成特定组成和浓度的稀释的反应产物混合物。然后处理该溶液以便形成至少两种产物混合物，其中一种产物基本上不溶于有机溶剂中的不含铝氧烷的烃基铝，另一种是在烃基铝和烃基铝氧烷的有机溶剂中组成的有机铝化合物的浓缩溶液其中铝氧烷的量远远超过烃基铝的量。将水加入到通过将水输送到烃基铝化合物和/或铝氧烷的溶剂溶液中的溶剂环绕的孔口中，将水加入到烃基铝化合物和/或铝氧烷的溶剂溶液中是有利的。
