Abstract

1355218 4,4<SP>1</SP>-bis-{[4-anilino-6[bis-(2-hydroxyethyl)-amino]-1,3,5-triazin-2-yl]-amino}stilbene- 2,2-disulphonic acid CIBA-GEIGY AG 1 Nov 1971 [2 Nov 1970] 50677/71 Heading C2C [Also in Division C5] The invention comprises crystalline 4,4<SP>1</SP>-bis- {[4 - anilino - 6 - [bis-(2 - hydroxyethyl)- amino] - 1,3,5 - triazin - 2 - yl] - amino} - stilbene- 2,21-disulphonic acid which is prepared by acidifying the corresponding alkali metal salt. The acidification is effected at a pH between 2À0 and 6À0 and may be done by the use of a mineral or organic acid. The compound is used in detergent soap or laundry compositions.
