With a total of four patents to his name, Van Soolingen's work has had a considerable impact on the industry.

Latest Patents

One of his latest patents is a process for the preparation of benzyl alcohol. This innovative method involves the hydrolysis of a benzyl ester with water in the liquid phase, carried out without a strong acid or base at temperatures ranging from 40°C to 320°C. The benzyl ester can be selected from a group that includes benzyl formiate, benzyl propionate, benzyl acetate, and benzyl benzoate. The process allows for the optional addition of a weak acid to the reaction mixture. After hydrolysis, the mixture is cooled to between 80°C and 180°C to facilitate phase separation, resulting in benzyl alcohol with a high yield and purity exceeding 98%.

Another significant patent is a method for preparing salts of aspartame from N-protected aspartame. This method involves cleaving off the protective group by treating it with an acid in an aqueous medium, combined with methanol at temperatures between 0°C and 80°C. The process uses acesulphamic acid in a specific ratio to ensure adequate conversion to the desired salt, which is then isolated in precipitated form at temperatures of 30°C or lower.
