tribrometo de fósforo

Descrição:

tribrometo de fósforo (PBr₃) é um composto químico caracterizado por sua fórmula molecular, que consiste em um átomo de fósforo ligado a três átomos de bromo. Normalmente é um líquido incolor a amarelado à temperatura ambiente e tem um odor pungente. O PBr₃ é conhecido por sua reatividade, particularmente como um agente brominante na síntese orgânica, onde pode converter álcoois em brometos. Também é utilizado na preparação de compostos que contêm fósforo. A substância é altamente corrosiva e pode reagir violentamente com água, liberando ácido bromídrico e ácido fosfórico, o que exige manuseio e armazenamento cuidadosos em um ambiente seco. O PBr₃ tem um ponto de ebulição relativamente baixo em comparação com outros haletos de fósforo e é solúvel em solventes orgânicos. Devido à sua reatividade e potenciais perigos, medidas de segurança adequadas, incluindo o uso de equipamentos de proteção individual, são essenciais ao trabalhar com este composto.

Phosphorus tribromide

CAS: 7789-60-8

Phosphorus tribromide is a reactive chemical that is used mainly as an intermediate in the manufacture of other chemicals. It has been studied for its role in the treatment of bowel disease, including ulcerative colitis and Crohn's disease. Phosphorus tribromide reacts with copper chloride to form copper phosphorocyanate, which can be hydrolyzed to form trifluoroacetic acid. This reaction mechanism also produces hydrogen fluoride, which is toxic. Phosphorus tribromide can react with benzalkonium chloride to form an insoluble coordination complex. The coordination geometry of these complexes depends on the size and shape of the molecule and can change depending on pH levels. Toxicity studies have shown that phosphorus tribromide is not acutely toxic or harmful when ingested by humans but prolonged exposure may lead to irritation of skin and eyes, damage to lungs and kidneys, or death from inhalation of fumes.
