Title: Louis P Petersen: Innovator in Siloxane Chemistry
Introduction
Louis P Petersen is a notable inventor based in Latham, NY (US). He has made significant contributions to the field of siloxane chemistry, holding a total of 4 patents. His work has advanced the processes involved in the preparation of acyloxysilanes and siloxane polymers.
Latest Patents
One of his latest patents is titled "Continuous process for preparing acyloxysilanes." This patent describes a method for preparing acyloxysilanes by reacting a chlorosilane with an aliphatic carboxylic acid in a column at elevated temperatures. The process involves the upward flow of the carboxylic acid in vapor phase, countercurrent to the downward flow of chlorosilane. The improvement in this method includes introducing the carboxylic acid at a rate that exceeds 1.3 moles per gram atom of silicon-bonded chlorine, while removing low boiling reaction by-products from the top of the column. The acyloxysilane product is collected at the bottom of the column, with a preferred embodiment involving the preparation of methyltriacetoxysilane from methyltrichlorosilane and acetic acid.
Another significant patent is for the "Process for the continuous manufacture of siloxane polymers." This process focuses on the continuous production of diorganopolysiloxane polymers using a static mixer. In this method, dimethyl cyclic polysiloxane monomers are treated with a potassium silanolate catalyst. The efficiency of the static mixer is enhanced by the early introduction of a water chain-stopper, which ensures a plug flow condition within the polymerizer section.
