Title: Alan J Tompsett: Innovator in Amines Manufacturing
Introduction
Alan J Tompsett is a notable inventor based in Middlesbrough, GB. He has made significant contributions to the field of chemical engineering, particularly in the manufacture of amines. With a total of 3 patents to his name, Tompsett's work has advanced the efficiency and selectivity of amine production processes.
Latest Patents
One of his latest patents focuses on the manufacture of amines through a process that involves reacting a feed comprising methanol and/or dimethylether and ammonia over a binderless zeolite A catalyst. This innovative approach, particularly using a binderless zeolite 5A catalyst, enhances the selectivity towards dimethylamine over mono- and tri-methylamine. Additionally, the catalyst's lack of alkali metal not only increases its activity but also significantly improves its selectivity compared to similar catalysts that contain alkali metals. Another patent details the manufacture of amines from alcohols using zeolite FU-1 catalysts. This process involves reacting alcohols with ammonia in the presence of zeolite FU-1, where some protons have been replaced by monovalent cations, such as sodium. This method is particularly effective for producing methylamines, favoring the formation of monomethylamine and dimethylamine over trimethylamine.
