Title: Weiqiang Jiang: Innovator in Sucrose Chemistry

Introduction

Weiqiang Jiang is a notable inventor based in Anhui, China. He has made significant contributions to the field of sucrose chemistry, holding 2 patents that showcase his innovative methods and techniques.

Latest Patents

One of his latest patents is a method for preparing sucrose-6-ester. This method involves preparing a reaction solution of sucrose and an organo-tin compound, atomizing the solution to form droplets, and mixing these droplets with a gasified dehydration medium. This process allows the droplets to undergo a dehydration reaction, resulting in an intermediate mixture containing sucrose organic tin ester droplets. The method further includes separating this mixture to obtain a sucrose organic tin ester solution and a dehydrated gas-liquid mixture. The solution is then cycled through atomization and dehydration steps multiple times, followed by an acylation reaction with an organic acid anhydride to produce the sucrose-6-ester.

Another significant patent by Jiang is a post-treatment method for a sucrose-6-carboxylate chlorination reaction solution. This method entails adding ammonia water or water to the chlorination reaction solution to create a mixture, which undergoes a preliminary neutralization reaction. Ammonia gas is then introduced into the resulting solution at a specific temperature, adjusting the pH to a predetermined alkalinity range and conducting a reaction for a set period. Finally, the pH of the solution is adjusted using an acid to achieve a predetermined acidity range.
