ABSTRACT:
The present invention relates to a composition for preventing deposition of inorganic salts. It comprises 5.0-50.0% by weight of a phosphonomethylated derivative of 1,3-diaminopropanol-2 of the general formula: ##STR1## wherein n=1 to 20; 5.0 to 10.0% by weight of 1,3-diaminopropanol-2 and/or a derivative of 1,3-diaminopropanol-2 of the general formula: ##STR2## wherein n=1 to 20; 3.0-30.0% by weight of hydrochloric acid, 3.0-7.0% by weight of an alkali metal chloride, 0.5-2.5% by weight of a product of interaction of benzyl chloride, chlorobenzyl chloride, benzylidene chloride or a mixture of these chlorinated compounds with hexamethylenetetramine at a molar ratio thereof equal to 1:0.25-0.45 respectively; 0.5-4.0% by weight of a water-soluble organic solvent and water being the balance. The protective effect of the composition against deposition of inorganic salts is as high as 100%. The freezing point is as low as -100.degree. C., thus enabling the use of the composition under arctic climate conditions without the necessity of adding costly antifreeze agents.
