Title: Colin Nelson: Innovator in Chemical Processes

Introduction

Colin Nelson is a notable inventor based in Glasgow, GB. He has made significant contributions to the field of chemical processes, particularly in the area of diazotization and azo pigment production. With a total of 3 patents to his name, Nelson's work has advanced the efficiency and control of chemical reactions.

Latest Patents

One of Nelson's latest patents is the "Continuous diazotization process." This innovative method involves an automatically controlled continuous process for the diazotization or tetrazotization of aromatic amines. The process ensures that the rate of addition of inorganic nitrite is regulated by a polarovoltric method. This allows for the maintenance of a pre-selected concentration of unreacted nitrous acid throughout the reaction period.

Another significant patent is the "Dialysis monitored preparation of metal salts of azo pigments." This process features an azo dyestuff coupling method where the amount of excess diazo or coupling component is continuously monitored. The addition of these components is automatically controlled by an analyzer that incorporates a dialyzer module. This method enables the production of azo metal salt pigments derived from sulphonated intermediates.
