METHOD OF PRODUCING CORROSION INHIBITOR |
摘要 |
FIELD: chemistry.SUBSTANCE: method involves mixing a reaction product of oxyethylidenediphosphonic acid and ascorbic acid and/or gluconic acid with tripolyphosphates of alkali metals and a reaction product of orthophosphoric acid with an alkali metal hydroxide with the weight ratio of the reaction product of oxyethylidenediphosphonic acid and ascorbic acid and/or gluconic acid with tripolyphosphates of alkali metals and the reaction product of orthophosphoric acid with an alkali metal hydroxide of 1:1-3, respectively.EFFECT: obtaining a corrosion inhibitor having high effectiveness of protecting process equipment from corrosion in aqueous media with different mineral content with a wide pH range, high stability of anti-corrosion properties and storage stability of the composition of the inhibitor.3 ex |
