  • Process for preparing a scaling inhibitor
    Patent number: 4746465
    Abstract: The present invention relates to a process for preparing a scaling inhibitor. The process comprises reacting 1,3-diaminopropanol-2 and/or polyhydroxypropylenepolyamines of the general formula: ##STR1## wherein n=2 to 20, with formaldehyde and phosphorus trichloride in an aqueous medium at a temperature of 35.degree. to 50.degree. C.; formaldehyde and phosphorus trichloride being used in amounts smaller than their stoichiometric amounts as calculated for the starting amines.The inhibitor prepared by the process according to the present invention ensures an effective protection against scaling, e.g. of barium sulphate, calcium sulphate and calcium carbonate. The process also features a low temperature of the synthesis of the inhibitor.

  • Composition for preventing deposition of inorganic salts
    Patent number: 4551262
    Abstract: The present invention relates to a composition for preventing deposition of inorganic salts. The composition incorporates 0.1-4.5% by weight and 1,3-diaminopropanol-2 and/or of a derivative of 1,3-diaminopropanol-2 of the general formula: ##STR1## wherein n=2 to 20, 5.0-50.0% by weight of a phosphonomethylated derivative of 1,3-diaminopropanol-2 in the form of a salt of an alkali metal and/or ammonium salt of the general formula: ##STR2## wherein n=1 to 20, M is an alkali metal or NH.sub.4, 3.0-12.0% by weight of an alkali metal chloride, ammonium chloride or a mixture of both and water to 100%. The composition effectively prevents scaling of inorganic salts, e.g. barium sulphate, calcium sulphate and calcium carbonate.

  • Composition for preventing deposition of inorganic salts
    Patent number: 4525293
    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.
