ABSTRACT:
A process for the preparation of a trialkyl aluminum compound of the formula (RCH.sub.2 CH.sub.2).sub.3 Al, wherein R is hydrogen or alkyl having 1 to 18 carbon atoms, which process comprises (A) reacting aluminum, hydrogen, and a mixture of said trialkyl aluminum compound and the corresponding dialkyl aluminum hydride in a first stage to form a first product which is said dialkyl aluminum hydride alone or in admixture with unreacted trialkyl aluminum compound; (B) reacting said first product with an olefin of the formula RCH=CH.sub.2, where R has its earlier meaning, in a second stage to form a second product which is a mixture of said trialkyl aluminum compound and the corresponding dialkyl aluminum hydride; and (C) recycling a portion of this second product from said second stage to said first stage and reacting the remainder of said second product with further olefin of the formula RCH=CH.sub.2 in a third stage to form said trialkyl aluminum compound.
