| titleOfInvention | Pyrazoline compounds |
| abstract | The invention relates to pyrazoline compounds of formula ##STR1## wherein R 1 is hydrogen or methyl, R 2 and R 3 are each independently of the other methyl, ethyl or hydroxyethyl, R 4 is hydrogen or chlorine, R 5 and R 6 are each independently of the other hydrogen or methyl, R 7 is hydrogen, methyl or phenyl, n is 0 or 1, with the proviso that, if n is 0 and R 4 to R 7 are hydrogen, R 2 is methyl and R 3 is hydroxyethyl, and X.sup.⊖ is a C 1 -C 3 alkanoate, C 1 -C 4 alkanephosphonate, C 1 -C 4 alkanesulfonate, phosphite, sulfamate or glycolate anion and, if R 1 is methyl, X.sup.⊖ is also a methosulfate, chloride or bromide ion, to the preparation of said compounds, to the use thereof as fluorescent whitening agents, and to novel hydrazine intermediates of formula ##STR2## wherein R 2 and R 3 are methyl, ethyl or hydroxyethyl, and the acetone hydrazones and salts thereof. |
