Abstract
PROCEDIMIENTO PARA DESENGRASAR METALES MOJADOS POR ACEITES DE CORTE. CONSISTE EN OPERAR A UNA TEMPERATURA COMPRENDIDA ENTRE 20 Y 120 GRADOS, BAJO UNA PRESION PROXIMA A LA PRESION ATMOSFERICA, EMPLEANDO UN DESENGRASADOR FORMADO POR 1,1,1-TRICLOROETANO, POR UN NITROALCANO Y POR 2-METIL-2,3-EPOXIBUTANO. EL NITROALCANO UTILIZADO CONTIENE DE 1 A 4 ATOMOS DE CARBONO, USANDOSE CON PREFERENCIA EL NITROMETANO, EL NITROETANO, EL NITROPROPANO O UNA MEZCLA DE ESTOS COMPUESTOS. LA CANTIDAD DE NITROALCANO UTILIZADA EN LA COMPOSICION VARIA ENTRE 0,001 Y 1 MOL POR LITRO DE 1,1,1-NITROCLOROETANO.
