Patent GB-714457-A (GB)
Title: Manufacture of asymmetrical urea derivatives of monoazo-dyestuffs
IPC: C09B43/14
Filed: 1952-04-30
Abstract: The invention comprises disazo dyestuffs containing a single sulphonic acid group and of the general formula <FORM:0714457/IV(c)/1> (wherein R1 represents a p-phenylene residue), and the manufacture thereof by the action of phosgene on the appropriate aminomonoazo dyestuffs, so selected that the resulting asymmetrical urea derivative contains a single sulphonic acid group. The products are suitable for dyeing or printing cellulose materials, and may be treated on the fibre or partially on the fibre and partially in the dyebath with an agent yielding metal (especially copper).  The aminomonoazo dyestuffs of the general formula <FORM:0714457/IV(c)/2> employed as starting materials are obtainable by coupling diazotized 4-aminophenol-2-carboxylic acid-6-sulphonic acid with an amine of the benzene series (H - R1 - NH2) capable of coupling in paraposition to the amino group, or with the o -methanesulphonic acid thereof with subsequent splitting off of the o -methanesulphonic acid group.  The other component is obtainable by coupling diazotized 4-nitro- or 4-acetylamino-2-chloraniline with salicyclic acid (advantageously in an alkaline medium, e.g. one rendered alkaline with the hydroxide of an alkali metal, an alkaline-earth metal or magnesium) and then reducing the nitro group or hydrolysing the acetylamino group.  In examples, the coupling component H - R1 - NH2 is (1) m-toluidine or m-anisidine; (2) 1-amino-2-methoxy-5-methylbenzene; (3) 2 : 5-dimethylaniline or 2 : 5-dimethoxyaniline.  In example (4), copper is dyed with the first product of (3) from a bath containing sodium carbonate and sodium sulphate, yielding a greenish yellow dyeing which becomes more reddish on treatment in the same bath with complex sodium copper tartrate.  Specifications 455,274 and 619,969 are referred to.

Loaves &c. 13, Fig. 1, are fed by any suitable means on to the paper 1 positioned over the upper pocket 8, the spring bottom and sides 9, 10 of which are opened out to receive it by the advance of a cam-actuated rod 14, Figs. 1 and 4. A table 3, then in its right-hand position shown in Fig. 15, helps to position the loaf beneath a carrier 17, which, after the return of the frame 3 to the right, descends and forces the loaf and web 1 into the pocket. As the carrier 17 descends against the action of springs 20, toggle levers 27 are opened out and cause end blades 25 and a side blade 26 to close in upon and hold the loaf during the descent. The drum 6 then moves in an anti-clockwise direction for the first folding operations. After the severance of the wrapper from the web by a guillotine in a frame 33, on the table 3, the two outstanding portions of the wrapper are successively folded down to make a longitudinal fold by folders 59, 72 on a frame 40, which is swung to the right. A frame 95 is then moved to the right carrying folders 94 which make the first end folds, after which rods 91 move folders 90, 80 successively into position to make the second and third end folds. The folders having been withdrawn, the drum is rotated another stage, fixed folders 99 turning down the remaining end flaps upon the ends of the packet. When the wrapper is of waxed paper, the ends may be sealed by electric or gas heaters and subsequently cooled.
