Title: The Innovations of Robert C. Ligon
Introduction
Robert C. Ligon is a notable inventor based in Raleigh, NC (US). He has made significant contributions to the field of agrochemicals, holding a total of 5 patents. His work focuses on developing innovative compositions and processes that enhance the effectiveness of herbicides and pesticides.
Latest Patents
One of Ligon's latest patents involves phytopharmaceutical alloy compositions. These compositions are designed for the preparation of wettable-powder and powder suspension herbicidal products containing low-melting agrochemical agents, such as bromoxynil esters. The preferred compositions are co-melts of bromoxynil esters with at least one additional herbicide or pesticide, particularly atrazine. These compositions have higher melting points than the bromoxynil ester component, allowing for the avoidance or minimization of solvents and carriers in formulations. This innovation enables the processing of dry powders without the issues associated with the softening or melting of pure bromoxynil esters during grinding or milling. Additionally, compositions containing the alloys maintain selectivity in the presence of oil adjuvants.
Another significant patent by Ligon relates to a novel method for preparing 3-alkyl-substituted glutaric acids and 2-alkyl-substituted succinic acids. This process utilizes transition-metal catalyzed oxidation of 5-alkyl-substituted-1,3-cyclohexane-diones or 3-alkyl-substituted-5-ketohexanoic acids, showcasing his innovative approach to chemical synthesis.
