ABSTRACT:
The process of preparing higher aluminum alkyls by olefin chain growth on alkyl aluminum is improved by using on-line flow-through calorimetry to determine the aluminum concentration of a process stream, such as the aluminum alkyl feed stream, by reacting a sample portion of the process stream with a molar excess of alcohol and measuring the change in temperature. The aluminum concentration of the stream can then be adjusted as required to maintain it within a selected range.
