Title: Jon Carl Thunberg: Innovator in Chemical Processes

Introduction

Jon Carl Thunberg is a notable inventor based in Amherst, NH (US). He has made significant contributions to the field of chemistry, particularly in the development of processes for preparing various chemical compounds. With a total of 5 patents to his name, Thunberg's work has had a meaningful impact on industrial applications.

Latest Patents

One of Thunberg's latest patents is for a process for preparing iminodiacetonitrile. This process involves forming an aqueous reaction mixture by admixing water, hexamethylenetetramine, formaldehyde, and HCN. The iminodiacetonitrile is then formed by passing this mixture through a continuous reaction zone while maintaining a temperature between 50°C and 250°C. The resulting iminodiacetonitrile can be recovered or hydrolyzed to form an alkali metal salt of iminodiacetic acid, which can also be recovered or converted to iminodiacetic acid.

Another significant patent involves a composition useful for reducing the caking tendency of particulate sodium chloride. This aqueous solution is prepared by admixing nitrilotriacetonitrile and aqueous hydrochloric acid, followed by a reaction at temperatures between 25°C and 70°C. The pH of the resulting mixture is then adjusted to about 3-7 using sodium hydroxide, potassium hydroxide, or ammonia. This solution is beneficial in various applications, including inhibiting the crystallization of sodium chloride from brines.
