CAS 32503-27-8: Sulfato de hidrógeno de tetrabutilamonio
Descripción:
Sulfato de hidrógeno de tetrabutilamonio (TBAS) es un compuesto orgánico con la fórmula química C16H37NO4S. Es una sal de amonio cuaternario, caracterizada por su catión tetrabutilamonio y anión hidrógeno sulfato. TBAS es típicamente un sólido blanco a blanco sucio que es soluble en disolventes polares como agua y alcoholes, lo que lo hace útil en diversas aplicaciones, incluyendo como catalizador de transferencia de fase en síntesis orgánica. El compuesto exhibe propiedades típicas de las sales de amonio cuaternario, como alta estabilidad térmica y la capacidad de facilitar la transferencia de iones a través de fases. TBAS se emplea a menudo en la síntesis de compuestos orgánicos, particularmente en reacciones que involucran nucleófilos y electrófilos. Además, puede servir como tensioactivo debido a su naturaleza anfifílica, que le permite interactuar con sustancias tanto hidrofílicas como hidrofóbicas. Los datos de seguridad indican que, aunque TBAS se considera generalmente de baja toxicidad, se deben observar medidas adecuadas de manejo y seguridad para evitar posibles irritaciones o efectos adversos.

CAS:Phase transfer catalyst Tetra-n-butylammonium hydrogen sulfate shows antibacterial properties due to the presence of the quaternary amine and the counter ion. It serves as a phase-transfer catalyst, surface-active agent, solvent, intermediate, active ingredient for conditioners, antistatic agent, detergent sanitizers, softener for textiles and paper products, emulsifying agents and pigment dispersers. It is used as an efficient catalyst in the N-alkylation reactions of benzanilides, cyclization of beta-amino acids to beta-lactams, conversion of nitriles to amides, dehydrohalogenation of aryl 2-haloethyl ethers to give vinyl ethers and in the oxidation of alcohols.

CAS:Tetrabutylammonium hydrogensulfate (TBAS) is a trifluoroacetic acid salt of tetrabutylammonium. It is soluble in water and alcohols and can be used as an acid catalyst for many organic reactions. TBAS reacts with ethylene diamine to form the sulfate ester, which undergoes nucleophilic substitution with hydrogen fluoride to produce hydrofluoric acid. The reaction mechanism of TBAS consists of two steps: the first step involves the formation of a tetrahedral intermediate between the sulfonium cation and the fluoride anion, and the second step involves the nucleophilic attack by water on this intermediate. The x-ray crystal structure of tetrabutylammonium hydrogensulfate has been determined by NMR spectroscopy. This compound is chemically stable at room temperature but decomposes at higher temperatures.
