4,4'-BIS -4-MORPHOLINO-6 -(P-SULFOANILINO) -SYMM-TRIAZINYL -2-YL- AMINOSTILBENE-2,2' -DISULFOACID TETRASODIUM SALT AS AN OPTICALLY BLEACH AGENT Russian patent published in 1995 - IPC

FIELD: anilino-painting industry. SUBSTANCE: compound is synthesized by interaction of cyanurchloride with sodium sulfanylate in aqueous medium, in the presence of surface-active substance - disperser following by addition of 4,4'- diaminostilbene-2,2'- disulfoacid and morpholine to the reaction mass in the presence of triethanolamine and with urea addition. Synthesized compound at concentrations 0.5 and 40.75 g/l with regard to cotton fabric and 0.25; 0.5 and 1.0% with regard to polyamide fabric shows increased bleaching capability, and increased resistance for wet treatment (by 1 point). EFFECT: enhanced quality of synthesized compound. 5 tbl
