Abstract

Procedimiento para eliminar sustancias corneas de pieles de animales muertos, caracterizado porque se tratan las pieles de animales muertos con por lo menos una sustancia de la formula general (1), o por lo menos una sal de metales alcalinos, metales alcalinotérreos, de amonio o fosfonio, correspondiente, definiéndose las variables como sigue: R1, R4 son iguales o diferentes y seleccionados entre H, arilo C6-14 y alquilo C1-12, no sustituido o sustituido con uno o más grupos SH u OH; R2, R3 son iguales o diferentes y seleccionados entre H, arilo C6-14 y alquilo C1-12 no sustituido o sustituido con uno o más grupos SH u OH, en donde por lo menos un resto R2 o R3 es diferente de H o R1 y R4 son diferentes de H, y en donde en cada caso dos restos vecinos R1 a R4 pueden significar juntos alquileno; R5 es seleccionado entre H, alquilo C1-12, H-C=O o alquilo C1-4-C=O; X1, X2, X3 y X4 son seleccionados entre OH, SH y NHR5, en donde para el caso de que R1 a R4 contengan por lo menos un átomo de S, por lo menos uno de X1 a X4 significa SH, y para el caso de que R1 a R4 no contengan ningun átomo de S, por lo menos dos de X1 a X4 significan SH.
