Abstract
PROCEDIMIENTO PARA LA PREPARACION DE SULFOSALICILATOS DE HIDRAZINIO. EL PROCEDIMIENTO PARA LA PREPARACION DE SULFOSALICILATOS DE HIDRAZINIO DE FORMULA [NHSI2NHSI2]SIA [CSI6HSI3(COOH) (SOSI3H) (OH)]SIB*C EN DONDE A = 1 Y B > 1 HASTA < 2; SE CARACTERIZA PORQUE SE HACE REACCIONAR ACIDO SULFOSALICILICO Y/O SU HIDRATO CON HIDRAZINA Y/O SU HIDRATO EN UNA RELACION MOLAR DE 1 : 1 HASTA 3 : 1 EN UN MEDIO ACUOSO, A TEMPERATURAS DE 5 A 60GC. EL SULFOSALICILATO DE HIDRAZINIO SE PUEDE UTILIZAR PARA LA ESTABILIZACION EFICAZ COMO ANTIOXIDANTE DE COMPUESTOS DE ESTA/O (II), ESPECIALMENTE EN LA TINCION ELECTROLITICA DE ALUMINIO O ALEACIONES DE ALUMINIO.
