CAS 109-99-9: Tetrahidrofurano

Descrição: Tetrahidrofurano (THF) é um líquido incolor e volátil com um odor distinto de éter. É um éter cíclico e serve como um solvente importante na química orgânica devido à sua capacidade de dissolver uma ampla gama de compostos polares e não polares. O THF tem um baixo ponto de ebulição e uma pressão de vapor relativamente alta, tornando-o útil em várias aplicações, incluindo como solvente para polímeros e na produção de produtos farmacêuticos. Sua estrutura química apresenta um anel de cinco membros contendo quatro átomos de carbono e um átomo de oxigênio, contribuindo para sua reatividade e capacidade de participar em várias reações químicas, como a polimerização. O THF é higroscópico, o que significa que pode absorver umidade do ar, o que pode afetar suas propriedades e reatividade. Também é inflamável e deve ser manuseado com cuidado, utilizando medidas de segurança apropriadas para evitar inalação ou contato com a pele. Além disso, o THF pode formar peróxidos após exposição prolongada ao ar, necessitando de práticas adequadas de armazenamento e manuseio para mitigar riscos.
