Abstract
APLICAçãO DE COMPOSTOS CARBONìLICOS NO PROCESSO DE CURTIMENTO DE COUROS. Aplicação de compostos carbonílicos no processo de curtimento de couros, compreendendo a utilização de <sym>-hidróxi cetónicos selecionados que apresentam fórmula geral (I) onde R pode ser um grupo alquila linear ou ramificado ou ainda aromático e R¹ e R² podem ser hidrogênio, alquila linear ou ramificado ou ainda aromático como por exemplo R¹ = R² = H e R = -CH~ 2~CH~ 3~ ou preferencialmente R¹ = R² = H e R = -CH~ 3~, ou ainda a utilização de compostos <225>-hidróxi cetonas selecionados apresentando fórmula geral (II) onde R pode ser um grupo alquila linear ou ramificado ou ainda aromático como por exemplo R, R¹ e = -CH~ 3~ e R³ = H, preferencialmente R, R² e R³ = -CH~ 3~ e R¹ = H Aplicação de compostos carbonílicos no processo de curtimento de couros, podendo ser utilizados em solução aquosa em concentrações que podem variar de 0,1% até seu estado puro, ou seja 100%, ou ainda em misturas com outros compostos orgânicos que atuem como diluente.APPLICATION OF CARBONILIC COMPOUNDS IN THE LEATHER PROCESSING PROCESS. Application of carbonyl compounds in the leather tanning process, comprising the use of selected ketone <sym> -hydroxy which have a general formula (I) where R can be a linear or branched or aromatic alkyl group and R¹ and R² can be hydrogen, linear or branched or aromatic alkyl such as R¹ = R² = H and R = -CH ~ 2 ~ CH ~ 3 ~ or preferably R¹ = R² = H and R = -CH ~ 3 ~, or the use of compounds < 225> -hydroxy ketones selected presenting the general formula (II) where R can be a linear or branched alkyl group or aromatic as for example R, R¹ and = -CH ~ 3 ~ and R³ = H, preferably R, R² and R³ = -CH ~ 3 ~ and R¹ = H Application of carbonyl compounds in the leather tanning process, which can be used in aqueous solution in concentrations that can vary from 0.1% to its pure state, ie 100%, or in mixtures with other organic compounds that act as a diluent.
