Abstract

"PROCESSO PARA REMOVER SUBSTáNCIAS QUERATINOSAS DE PELES DE ANIMAIS MORTOS, COURO, COMPOSTO, E, PROCESSO PARA PREPARAR O MESMO". A invenção refere-se a um método para a extração de queratina de peles de animal morto, caracterizado pelo fato de tratar as peles de animal morto com uma substância de fórmula geral (I), ou com pelo menos um sal de metal alcalino, sal de metal alcalino-terroso, sal de amónio, ou sal de fosfónio correspondente, as variáveis possuindo as seguintes definições: R¬ 1¬, R¬ 4¬ = juntos ou independentemente, H, C~ 6~-C~ 14~-arila, C~ 1~-C~ 12~-alquila, não substituídas ou substituídas com um ou vários grupos SH ou OH, R¬ 2¬, R¬ 3¬ =juntos ou independentemente, H, C~ 6~-C~ 14~-arila, C~ 1~-C~ 12~-alquila, não substituídas ou substituídas com um ou vários grupos SH ou OH, sendo que pelo menos um de R¬ 2¬ ou R¬ 3¬ não é H, ou R¬ 1¬ e R¬ 4¬ não são H e dois grupos vicinais de R¬ 1¬ a R¬ 4¬ podem ser C~ 3~-C~ 10~-alquileno, R¬ 5¬ = H, C~ 1-C~ 12~-alquila, H-C=O ou C~ 1~-C~ 4~-alquil-C=O, X¬ 1¬, X¬ 2¬, X¬ 3¬ e X¬ 4¬ = OH, SH ou NHR¬ 5¬, sendo que se R¬ 1¬ a R¬ 4¬ contiverem pelo menos um átomo de enxofre, pelo menos um de X¬ 1¬ a X¬ 4¬ = SH e se R¬ 1¬ a R¬ 4¬ não contiver átomo de enxofre, pelo menos dois de X¬ 1¬ a X¬ 4¬ = SH.
