Title: George H Sankey: Innovator in Sucrose Chemistry
Introduction
George H Sankey is a notable inventor based in Reading, GB. He has made significant contributions to the field of sucrose chemistry, holding a total of 5 patents. His work has advanced the understanding and application of sucrose derivatives, particularly in the food industry.
Latest Patents
One of his latest patents involves a continuous process for the preparation of sucrose 6-esters. This method includes several steps: first, reacting a solution of sucrose in an inert organic solvent with a reagent, such as a trialkyl orthoester or a ketene acetal, in the presence of an acid catalyst. This reaction produces a sucrose alkyl 4,6-orthoester. The next step involves treating this orthoester under mild aqueous acidic conditions to yield a mixture of sucrose 4- and 6-monoesters. Following this, the mixture is treated with a base to convert the sucrose 4-ester into sucrose 6-ester. Finally, the solution is neutralized, and the sucrose 6-ester is isolated. Sucralose is then prepared by chlorinating the sucrose 6-esters obtained through this innovative process.
Career Highlights
Throughout his career, George H Sankey has worked with prominent companies, including Tate & Lyle Public Limited Company. His expertise in sucrose chemistry has positioned him as a key figure in the development of new food ingredients.
