Introduction

Colin John Bennie is a notable inventor based in Grangemouth, GB. He has made significant contributions to the field of chemical processes, holding a total of 2 patents. His work focuses on innovative methods for synthesizing important chemical compounds.

Latest Patents

Colin's latest patents include a chemical process for preparing 3-Isochromanone. This process involves partially chlorinating o-tolylacetic acid with sulphuryl chloride or chlorine gas in an inert organic solvent, utilizing a free radical initiator. The initial product, 2-chloromethylphenylacetic acid, is then converted to 3-isochromanone through treatment with a base. This method effectively separates unreacted o-tolylacetic acid, which is in the form of a salt, using a phase separation technique. The process not only reduces the formation of unwanted, over-chlorinated by-products but also enhances overall efficiency. Another patent details a process for preparing 3-isochromanone by contacting an o-xylene-α,α'-dihalide with carbon monoxide in the presence of a catalyst and a hindered amine base within a liquid medium that includes water and a tertiary alcohol.
