Title: The Innovative Contributions of Dieter Weber
Introduction
Dieter Weber is a notable inventor based in Kelkheim (Taunus), Germany. He has made significant contributions to the field of chemistry, particularly in the development of advanced pigments. With a total of two patents to his name, Weber's work has had a considerable impact on the industry.
Latest Patents
Weber's latest patents include the synthesis of 1,3,4-Oxadiazoles, specifically 2,5-Bis-(4'-aminophenyl)-1,3,4-oxadiazoles. These compounds are chlorinated in the phenyl nuclei and are produced by condensing hydrazine or a hydrazine yielding agent with chlorinated benzoic acids or acylating acid derivatives. The process involves ring closure of the resulting bis-hydrazide to yield the oxadiazole. The products serve as bis-diazo components, particularly for pigments that exhibit high tinctorial strength, clear and pure shades, and excellent fastness to light, heat, and solvents. Another significant patent involves disazo pigments derived from 3,8-diamino-phenanthridone-(10). These compounds are obtained by bis-diazotizing 3,8-diamino-phenanthridone-(10) and coupling it with enolizable ketomethylene coupling components. The resulting pigments are characterized by high tinctorial strength and resistance to migration, heat, light, and chemicals.
