Title: Innovations of John K Roberg
Introduction
John K Roberg is a notable inventor based in Baton Rouge, LA (US). He has made significant contributions to the field of chemistry, particularly in the synthesis of aluminoxanes. With a total of 4 patents to his name, Roberg's work has paved the way for advancements in chemical processes.
Latest Patents
One of Roberg's latest patents is the "High yield aluminoxane synthesis process." This innovative process involves feeding water, hydrocarbylaluminum such as trimethylaluminum, and organic solvent such as toluene into a reactor in controlled proportions and under temperature control. The result is a dilute reaction product mixture of specified composition and concentration. This solution is then processed to form at least two product mixtures. One mixture is essentially aluminoxane-free hydrocarbylaluminum dissolved in organic solvent, while the other is a concentrated solution of organoaluminum compounds composed mainly of hydrocarbylaluminum and hydrocarbylaluminoxane in organic solvent. This process fulfills the need for practical, commercially feasible technology capable of producing concentrated aluminoxane solutions with no significant yield losses. It can be applied to both batch and continuous modes of operation.
Another significant patent is the "Process for making aluminoxanes." This improved process involves the addition of water to a solvent solution of a hydrocarbylaluminum compound and/or an aluminoxane. The water is fed through an orifice surrounded by a flow of solvent, which carries the water into the solvent solution of hydrocarbylaluminum compound and/or aluminoxane.
