Изобретение относится к способу получения эмульгатора для жирования кож и может быть использовано в кожевенно-обувной промышленности в процессах эмульсионного жирования кож. Сущность изобретения: эмульгаторы получают сульфированием природного жира или его смеси с оксиэтилированным алкилфенолом или оксиэтилированными алифатическими спиртами в реакторе проточного типа при перемешивании 24%-ным олеумом при 70-120oС в течение 1,5 - 2 мин с последующей нейтрализацией продукта гидроксидом натрия или его смесью с триэтаноламином при 40 - 70oС.The invention relates to a method for producing an emulsifier for fatliquoring of leathers and can be used in the leather and footwear industry in the processes of emulsion fatliquoring of leathers. The essence of the invention: emulsifiers are obtained by sulfonation of natural fat or its mixture with ethoxylated alkyl phenol or ethoxylated aliphatic alcohols in a flow-type reactor with stirring with 24% oleum at 70-120 o C for 1.5 to 2 minutes, followed by neutralization of the product with sodium hydroxide or its mixture with triethanolamine at 40 - 70 o C.
