Title: Marinus P Rijkers: Innovator in Crystallization Techniques
Introduction
Marinus P Rijkers is a notable inventor based in Stein, Netherlands. He has made significant contributions to the field of crystallization, particularly in the production of aspartame. With a total of 3 patents to his name, Rijkers has developed innovative methods that enhance the efficiency and quality of crystallization processes.
Latest Patents
Rijkers' latest patents focus on the crystallization of α-L-aspartyl-L-phenylalanine methyl ester, commonly known as aspartame. One of his patents describes an improved method for crystallization from an aqueous solution by utilizing conductive cooling while avoiding turbulence in the crystallizing system. This method involves cooling to a temperature not lower than 10°C in the presence of at least 0.1% by weight of a C3-8 ketone. The specific amount of ketone and temperature are carefully chosen to ensure a homogeneous solvent system at the start of crystallization, resulting in an open drainable network of aspartame crystals.
Another patent outlines a method for crystallizing aspartame that includes several steps. These steps involve providing dispersed droplets of a fluid mixture containing aspartame and water, and passing these droplets through a water-immiscible fluid zone under effective temperature and dispersive conditions. This process leads to the formation of a state of initial relative supersaturation of aspartame, ultimately resulting in a slurry of crystalline aspartame.
