Taschenbuch. Zustand: Neu. Neuware - 'The Effect of Sulfur on the Color of Tri-Phenyl Methane Dyes and Certain Phthaleins' is a detailed scientific investigation into the chemical properties and optical behavior of organic coloring agents. Authored by Harold Stephens Holt, this work explores the specific structural and aesthetic… alterations that occur when sulfur is integrated into various dye molecules. The study provides an analytical look at tri-phenyl methane derivatives and phthaleins, aiming to determine how specific molecular substitutions influence light absorption and the resulting chromaticity.This technical treatise offers significant insights into the development of synthetic dyes and the evolution of organic chemistry in the early 20th century. By documenting precise experimental results and chemical syntheses, the work contributes to the foundational knowledge of material science and industrial chemistry. It serves as a valuable resource for researchers and historians interested in the history of laboratory practices, the chemistry of colorants, and the relationship between molecular structure and physical properties. This study remains a notable example of the rigorous empirical research that defined early modern chemical inquiry.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
