Title: The Innovations of Roger L Briggs
Introduction
Roger L Briggs is a notable inventor based in Midland, MI (US). He has made significant contributions to the field of chemistry, particularly in the area of alkali metal phenates and salicylic acid production. With a total of 2 patents to his name, his work has implications for various industrial applications.
Latest Patents
One of Roger's latest patents is titled "Carbonation of alkali metal phenates." This invention describes a method for efficiently carbonating a dry alkali metal phenate with carbon dioxide under pressure. The process involves maintaining the temperature below about 135 degrees Celsius until at least 25 mole percent of the carbon dioxide necessary for complete carbonation is absorbed. This method is particularly useful for producing the sodium salt of salicylic acid.
Another significant patent is the "Process for making pure salicylic acid." In this invention, alkali metal salicylate is efficiently acidified, and the salicylic acid product is formed and contemporaneously sublimed by contacting the salicylate as a solid with gaseous hydrogen chloride. The temperature of the hydrogen chloride is controlled to ensure that the heat required to sublime the salicylic acid is predominantly supplied by the heat of reaction with the alkali metal salt of the carboxylic acid.
