FIELD: chemistry.
SUBSTANCE: invention relates to inhibition of scaling in process flows during industrial production. Method of inhibiting scale formation formed during production of phosphoric acid using a wet method is carried out by adding a scale inhibiting amount of the reagent. Reactant has at least one amine portion comprising at least one primary amine and at least one hydrocarbyl portion, having a group which imparts insolubility properties attached thereto at least one step of producing phosphoric acid using a wet method.
EFFECT: efficient inhibition of scale formation in processes of obtaining phosphoric acid by a moist method.
