Abstract
LA CORROSIVIDAD AL COBRE DE LOS POLISULFUROS DIHIDROCARBILO SE REDUCE SI SE TRATAN CON UNA SUSTANCIA QUE CONTENGA METALES ALCALINOS O QUE CONTENGA METALES ALCALINO-TERREOS CAPAZ DE DISOLVER EL AZUFRE ELEMENTAL (EJ. HIDROXIDO SODICO O SULFURO SODICO). EL PROCESO SE REALIZA EN UN MEDIO DE REACCION LIQUIDO COMPUESTO DE UNA MEZCLA DE AGUA Y AL MENOS UN ALCOHOL SOLUBLE EN AGUA. LOS EXPERIMENTOS HAN DEMOSTRADO QUE ES POSIBLE REDUCIR LA CORROSIVIDAD AL COBRE MEDIANTE EL USO DE ESTE PROCESO A UN NIVEL INFERIOR AL PRESENTADO POR UN PRODUCTO QUE SE FORMA TRATANDO EL MISMO POLISULFURO DE DIHIDROCARBILO INICIAL DE LA MISMA FORMA PERO EN UN MEDIO LIQUIDO COMPUESTO SOLAMENTE DE AGUA.
