Title: Kuan-Chieh Tseng: Innovator in Chemical Synthesis
Introduction
Kuan-Chieh Tseng is a notable inventor based in Pingtung, Taiwan. He has made significant contributions to the field of chemical synthesis, holding 2 patents that showcase his innovative methods. His work emphasizes efficiency and environmental sustainability, making him a key figure in his area of expertise.
Latest Patents
Tseng's latest patents include a method for synthesizing 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide or its derivatives. This method involves introducing 6-chloro-6H-dibenz[c,e][1,2]oxaphosphorin or its derivative, an acid compound, and water into a reacting chamber. This process results in an organic layer containing the desired compound and an aqueous layer. The use of an external acid compound enhances the yield while minimizing side reactions. Additionally, this method is a one-pot operation that combines hydrolysis, dehydration, and cyclization, which reduces the need for intermediate purification, saving time and costs while also decreasing environmental pollution.
Another significant patent by Tseng is a method for preparing three types of benzidine compounds in a specific ratio. This method utilizes two types of diphenylamine compounds and one type of biphenyldihalide compound as reactants. By mixing these with an organic solvent and an additive, Tseng's method synthesizes benzidine compounds in a single step. The resulting compounds exhibit excellent photoelectric characteristics, making them suitable for use in charge transporting layers in organic photo-conductive drums.
