FIELD: chemistry.
SUBSTANCE: invention relates to novel chemical compounds as salt-deposition inhibitors and can be used in oil industry in oil extraction, in particular in system of sewage water utilising, as well as in systems of circulating water supply of industrial enterprises. Suggested is complexonate of nitrylotri(methylenephosphonato)-2-phenyl-3-ethyl-8-oxychinolin sodium salt of formula 
as salt-deposition inhibitor.
EFFECT: obtaining salt-deposition inhibitor characterised by high efficiency with low consumption rate under conditions of intensive degasing.
