Abstract
A method for preparing a composition with low corrosive effect and low freezing point, in which an ammonium cation source is mixed with a carboxyl anion source in an appropriate molar or weight ratio, either without a medium or by using an appropriate medium for obtaining liquid or water-soluble organic ammonium carboxylate of formula (1): [NR1R2R3R4]+n [R5(COO)n]−n, in which R1, R2, and R3 are selected from hydrogen, substituted and unsubstituted 1-6 carbon alkyl, R4 is a substituted or unsubstituted 1-6 carbon alkyl, R5 is hydrogen, a substituted or unsubstituted 1-6 carbon hydrocarbon and n is an integral 1-6, and, thereafter, a possible solvent is added while keeping the alkali or alkali-earth metal content of the composition in a range of 0.001-30 wt-%.
