| titleOfInvention | METHOD FOR PRODUCING POWDER CONTAINING ONE OR SEVERAL COMPLEX-FORMING SALTS |
| abstract | 1. A method of manufacturing a powder containing one or more complexing salts of the general formula in which R ′ is hydrogen or one of the moieties or R ′ ′ is hydrogen, an alkyl residue with 1-12 carbon atoms or a residue - (CH) -COOM, where q = 1-5 , n and m in each case are an integer from 0 to 5, and R ″ ″ represents hydrogen, or an alkyl residue with 1-12 carbon atoms, or an alkylene residue with 1-12 carbon atoms, which may be further substituted up to 5 hydroxyl groups, or one of the groups in each case, o and p are an integer from 0 to 5, and M independently means hydrogen, alkali metal, alkaline earth metal, ammonium or substituted ammonium in the corresponding stoichiometric amounts, obtained from an aqueous solution containing one or more complexing agents salts in a concentration of from 10 to 80% of the mass. relative to the total mass of the aqueous solution, by spray drying, which includes a spraying step and a drying step, characterized in that the spraying step is carried out with the addition of crystalline fine dust of the same salt or the same complexing salts as those contained in the aqueous solution, or one or more complexing salts different from them, with an upper limit of the average particle diameter of crystalline fine dust at least 2 times less than the lower limit of the average diameter of powder particles, obtained according to the method in an amount of from 0.1 to 20 wt.%, relative to the mass of powder prepared in accordance with sposobom.2. The method according to claim 1, characterized |
