1-Metil-2-pirrolidinona

A 1-Metil-2-pirrolidinona (NMP), com número CAS 872-50-4, é um líquido incolor, viscoso e de odor ligeiramente característico, com ponto de ebulição elevado (aproximadamente 202 °C) e baixa volatilidade, sendo miscível com água e a maioria dos solventes orgânicos. Trata-se de uma lactama cíclica substituída, classificada tecnicamente como uma amida heterocíclica saturada, derivada da pirrolidina. É amplamente empregada como solvente de alto desempenho em processos industriais devido à sua excelente capacidade de dissolver polímeros, resinas, sais e compostos orgânicos, além de apresentar boa estabilidade térmica e química. Sua principal aplicação situa-se no setor de revestimentos e tintas, especialmente em sistemas de vernizes para eletrônicos e revestimentos anticorrosivos, bem como na produção de polímeros como poliimidas e aramidas. Além disso, atua como intermediário químico essencial na síntese de agroquímicos, fármacos e aditivos para baterias de íon-lítio.
