Abstract

USO DE éSTERES 1-ALQUIL-5-OXOPIRROLIDINA-3-CARBOXìLICOS COMO INIBIDORES DE HIDRATOS DE GASES COM MELHOR BIODEGRADABILIDADE. A presente invenção refere-se ao uso de ésteres 1 -alquil-5-oxopirrolidina-3-carboxílicos, preparáveis pela esterificação de álcoois que têm entre 1 e 100 grupos hidroxila com ácido 1-alquil-5-oxopirrolidina-3-carboxílico, em quantidades entre 0,01 e 2% em peso, para impedir a formação de hidratos de gases em sistemas aquosos que ficam em contato com uma fase orgânica gasosa, líquida ou sólida.
