Abstract

28,910. Ellis, G. B., [Chemical Works, (formerly Sandoz)]. Dec. 15. Primary disazo, trisazo, and tetrakisazo dyes are obtained by combining resorcin in an alkaline solution on the one hand with one molecule of a diazosulphonic acid of the benzene or naphthalene series or of a diazo compound of a monoazo dye from a diazosulphonic acid of the benzene or naphthalene series or an o-diazophenol and ClÞve's acids, and on the other hand with one molecule of an o-diazophenol or of a diazo compound of a monoazo dye from an o-diazophenol and ClÞve's acids. According to examples: -naphthionic acid is diazotized and coupled with resorcin and the product is coupled with the diazo compound of p-chlor-o-aminophenol; the monoazo dye from diazotized sulphanilic acid and ClÞve's acid is diazotized and coupled with resorcin. and the product is coupled with the diazo compound of p-nitro-oaminophenol: the monoazo dye from diazotized p-nitro-o-aminophenol and ClÞve's acid is diazotized and coupled with resorcin and the product is coupled with diazotized naphthionic acid; the monoazo dye from diazotized picramic acid and ClÞve's acid is diazotized and coupled with resorcin and the product is coupled with diazotized picramic acid. The products dye wool in acid baths various shades of brown which may be after-chromed.
