Conductividad de alquilaminas oxietilenadas.

Abstract

Les Alkylamines Oxyéthylénées sont des produits surfactifs qui peuvent être utilisés comme auxiliaires de teinture de la laine et du polyamide. L'action des produits auxiliaires de teinture dépend, en grande partie, de leur état dans la solution. Dans le présent travail, on étudie la conductivité des solutions de Laurylamines et Stéarylamines a différents degrés d'oxyéthylénation, puisque la variation de la conductivité fournit de l'information concernant l'état de ces composés dans la solution. On analyse l'influence de la longueur de la chaine alkylique, du nombre de mols d'oxyde d'éthylene présents dans la molécule, de la concentration et de la température.

Las Alquilaminas Oxietilenadas son productos tensioactivos que pueden emplearse como auxiliares de tintura de lana y poliamida. La acción de los productos auxiliares de tintura depende en gran manera de su estado en la disolución. En el presente trabajo se estudia la conductividad de las disoluciones de Laurilaminas y Estearilaminas de diferentes grados de oxietilenación ya que la variación de la conductividad proporciona información acerca del estado de tales compuestos en la solución. Se analiza la influencia de la longitud de la cadena alquílica, del número de moles de óxido de etileno presentes en la molécula, de la concentración y de la temperatura.

Oxyethylenated alkylamines are surface agents which can be used as auxiliary products in wool and polyamide dyeing. The action of the dyeing auxiliary products depend largely on the dissolution state. This paper examines the conductivity of laurylamine and stearlylamine dissolutions with different levels of oxyethylenation, since the variation of conductivity provides information on the state of the above compounds in the solution. The influence of the length of the alkyl chain, of the number of mols of ethylene oxyde in the molecule, of the concentration and of temperature are also studied.
