Claims (7)

1. Способ получения минеральной коллекторной композиции, включающий 2-взаимодействия сложного эфира C6-С22 жирной кислоты с гидроксиламиновой солью и основанием в присутствии масла и воды для получения алкилгидроксаматной соли; затем подкисление алкилгидроксаматной соли, с образованием органического слоя и водного слоя; и отделение органического слоя от водного слоя с получением минеральной коллекторной композиции, содержащей смесь C6-С22 жирной гидроксамовой кислоты и масла.1. A method of obtaining a mineral collector composition, comprising 2-interaction of the ester of a C 6 -C 22 fatty acid with a hydroxylamine salt and a base in the presence of oil and water to obtain an alkyl hydroxamate salt; then acidification of the alkyl hydroxamate salt to form an organic layer and an aqueous layer; and separating the organic layer from the aqueous layer to obtain a mineral reservoir composition containing a mixture of C 6 -C 22 fatty hydroxamic acid and oil. 2.

Способ по п. 1, в котором гидроксиламиновая соль представляет собой сульфатную или гидрохлоридную соль. 6. The method according to p. 1, in which the hydroxylamine salt is a sulfate or hydrochloride salt. 7. Способ по п. 1, дополнительно включающий поддерживание органического слоя при температуре выше температуры, при которой гидроксамовая кислота затвердевает. 7. The method according to p. 1, further comprising maintaining the organic layer at a temperature above the temperature at which hydroxamic acid solidifies.
