Title: The Innovative Contributions of Donald R. Napier
Introduction
Donald R. Napier is a notable inventor based in Corpus Christi, TX (US). He has made significant contributions to the field of catalysis and polymerization, holding a total of 2 patents. His work has advanced the understanding and application of chemical processes in various industries.
Latest Patents
One of Napier's latest patents is titled "Phase transfer catalysis of heterogeneous reactions by quaternary salts." This patent describes a process for catalyzing heterogeneous ionic organic reactions in a system of multiple liquid phases. In this system, at least two of the reactants are located in different phases, which differ in polarity. The catalysis is achieved by introducing certain organic quaternary salts that are more soluble in the least polar reactant-containing phase. The structural formula of the quaternary salt catalysts utilized is (AM).sup.+X.sup.-, where A represents an organic portion of the salt molecule, M is selected from nitrogen, phosphorus, arsenic, antimony, and bismuth, and X.sup.- is an anion that dissociates in an aqueous environment.
Another significant patent by Napier is the "Addition polymerization process." This patent discloses a polymerization catalyst that consists of a cupric salt, a copper chelating agent, and a cyanide salt for polymerizing vinyl monomers. This catalyst system is less hazardous compared to traditional persulfate and peroxide catalysts. It also results in a higher molecular weight of the polymer under comparable conditions and is not consumed by certain impurities that react with prior art catalysts.
