Abstract
USO DE éSTERES DE áCIDO PIROGLUTáMICO COMO INIBIDORES DE HIDRATO DE GáS COM APERFEIçOADA BIODEGRADABILIDADE. A presente invenção refere-se ao uso de ésteres de ácido piroglutâmico, que podem ser produzidos através de esterificação de álcoois tendo de 1 a 100 grupos hidroxila com ácido piroglutâmico e/ou ácido glutâmico, com a condição de que o álcool tem não mais que um grupo éster ou não mais que um grupo ácido carboxílico, em quantidades de 0,01 a 2% em peso para prevenção de formação de hidratos de gás em fases aquosas que são conectadas a uma fase orgânica gasosa, líquida ou sólida.
