Title: John Raymond Tyndall: Innovator in Plant Growth Regulation
Introduction
John Raymond Tyndall is a notable inventor based in Pisgah Forest, NC (US). He has made significant contributions to the field of plant growth regulation, holding a total of 2 patents. His work has had a lasting impact on agricultural practices, particularly in the cultivation of commodity plants.
Latest Patents
Tyndall's latest patents include a method for producing Mepiquat chloride. This compound is synthesized through the reaction of N-methylpiperidine and chloromethane in an anhydrous liquid solvent. The solvents used include acetone, methyl ethyl ketone, toluene, tetrahydrofuran, isopropanol, acetonitrile, N,N-dimethylformamide, and methylene chloride, all in the absence of sodium hydroxide. Mepiquat chloride precipitates as a high-purity solid, which can be sealed into a water-soluble pouch or encapsulated solid form for easy handling. This innovative approach minimizes human exposure and eliminates the need for disposal of containers in contact with the compound. Mepiquat chloride is particularly useful in the growth of cotton plants, where it regulates growth at various stages to enhance fruit production. Another patent involves a method for preparing 2-bromo-4,6-dinitromesitylene with minimal impurities, achieved by mixing fuming sulfuric acid with bromomesitylene and adding concentrated nitric acid.
