Abstract: In deinking printed waste paper by beating in aqueous medium in the presence of deinking agent and purification by washing of flotation, the deinking agent (I) comprises hydrogenated 24-50C dimeric acids with an iodine number \} 20 and/or their alkali(ne earth) metal and/or ammonium salts and/or alkoxylation products. Also claimed is the use of these acids and derivatives as (I) for deinking printed waste paper. Preferably (I) consists of 30-40C acids and/or alkoxylation products, especially a 36C acid with an iodine number \} 7.5. The waste paper is beaten in the presence of aqueous sodium hydroxide solution, water glass, hydrogen peroxide (H2O2) and optionally a ligand. Alternatively, beating and flotation are carried out at pH 6.5-8.8 in the absence of these additives and surfactants.

Abstract: Hydroxyalkylaminocarboxylic acids have the general formula (I), in which R is hydrogen, a C1-C4 alkyl residue or a group having the formulas -CHR -CH(OH)-R or -CH2)n-COOM, in which n equals 1 to 4; R and R represent independently from each other hydrogen, a phenyl residue or an alkyl or alkenyl residue that may in addition bear phenoxy groups, carboxylic acid C1-C4-alkyl ester groups or ester groups derived from triglycerides based on unsaturated C10-C22 fatty acids and may be interrupted by non-adjacent oxygen atoms, the sum of all C atoms from both residues R and R being at least 4; A is a linear or branched C1-C6 alkylene group that may in addition bear a hydroxyl group and/or a group having the formula COOM, and R and A may form together with the N atom a 5- or 6-membered ring; and M is hydrogen, alkaline metal, ammonium or substituted ammonium. These hydroxyalkylaminocarboxylic acids are useful as complexing agents for alkaline earth and heavy metal ions.
