Patent GB-1010233-A (GB)
Title: Process for the production of water-soluble disazo dyes
Inventor: ISCHER HANS
IPC: C09B43/16
Filed: 1961-10-27
Abstract: The invention comprises water-soluble disazo dyes of the formula <FORM:1010233/C4-C5/1> wherein A represent the radical of an azo component coupled in ortho-position to a hydroxy or amino group, which latter group may be substituted, B represents a diphenyl group which may be substituted, D represents an acyl or beterocyclic radical which is free of reactive substituents and in which the nucleus C may be further substituted, the dye molecule containing sufficient water-solubilizing groups to provide water-solubility. The dyes are prepared by reacting the corresponding amino disazo compounds with a functional derivative of an organic acid or with a heterocyclic compound containing at least one exchangeable halogen atom and when the resulting dyes contain further reactive substituents replacing these by non-reactive substituents the constituents being so chosen that the final dyes contain the number of water-solubilizing groups necessary to render it soluble in water. In an alternative process the diazo compound of an amine of the formula <FORM:1010233/C4-C5/2> is coupled with an appropriate hydroxy or amino naphthalene.  The term "reactive substituent" refers to a substituent capable of forming a chemical linkage with cellulose and polyamide fibres that is stable to treatment with boiling 50% aqueous pyridine solution.  The group A in the formula may be derived from such coupling components as hydroxy naphthalene mono-, di- and trisulphonic acids, amino-naphthol sulphonic acids and N-acyl and N-methyl derivatives thereof and 1-hydroxy-4-methylbenzene, 1-phenyl-3-methyl-5-pyrazolone, the group B from various 4,41-diamino-1,11-diphenyls substituted with such groups as methyl, ethyl, methoxy and sulphonic groups and the group C from various anilines optionally substituted in the nucleus with such groups as methyl, acetyl, methoxy, propionyl and butyryl.  Agents specified for the introduction of the group D include carboxylic halides an anhydrides, halogeno formic acid esters of alcohols and phenols, cyanuric halides and secondary condensation products thereof, and halopyrimidines, optionally containing substituents in the 5-position.  When reactive groups are present in substituents introduced they are converted to non-reactive groups, e.g. by reaction with amino, hydroxy or thio compounds.  The dyes are suitable for dyeing and printing cellulosic fibres, wool, silk, leather and synthetic polyamide fibres from weakly acid to weakly alkaline baths.  In an example 4,41-diamino - 5,51 - dimethyl - 1,11 - diphenyl - 2,21 -disulphonic acid is tetrazotized and coupled with 1-amino-3-methyl benzene and 1-hydroxy-naphthalene-4-sulphoni acid and the product acylated with lauroyl chloride.  Many additional examples are furnished and alternative starting materials specified.

A circuit for re-shaping distorted pulses at terminal 4 comprises a gate 29 controlled by bi-polar pulses obtained from a short-circuited delay line 1. Negative 1 Mc/s. pulses are fed from generator 3 down delay line 1 and reflected by the short-circuit 27 as positive pulses which render diode 21 conductive, correctly terminating the line by resistor 22. The duration (0.2 Ás.) of the pulses from generator 3 is made twice the transit time of line 1 so that the waveform on line 28 consists of a negative pulse followed immediately by a positive pulse. Transformer 17 may be omitted. Pulse gating and shaping circuits.-Square positive pulses of 0.8 Ás. duration are derived at terminal 6 from 0.6 Ás. trapezoidal pulses fed to terminal 4 by the action of the AND gate 29 under control of the waveform on line 28. The positive part of this waveform occurs during the flat top of the waveform fed to terminal 4 and biases off diodes 32, 36, enabling capacitor 40 (which may be stray capacitance) to change rapidly from the positive supply 35 via resistor 33 and diode 31, until the potential at terminal 4 is reached when the rise is limited by diode 30. The change on capacitor 40 is retained until the onset of the next negative edge of the waveform on line 28, when diode 36 conducts, discharging capacitor 40 into capacitor 37 and terminating the output pulse. Reference is made in the Provisional Specification to Specifications 528,310, 531,712 and 538,553.
