Abstract: 1445428 Dyeing textile materials HOECHST AG 10 Aug 1973 [11 Aug 1972] 37990/73 Heading D1L A process for exhaustion dyeing of textile materials of synthetic fibres or mixtures of synthetic and natural fibres while using a continuously circulating liquor in a closed system and dyestuffs which are only sparingly soluble in water, comprises the steps of dissolving the disperse dyestuffs in a water immiscible organic solvent, bubbling water at an elevated temperature through the organic solution to produce a saturated aqueous dyestuff solution, passing this aqueous solution through the material to be dyed, and recycling the aqueous solution depleted in dyestuff back through the organic solution for replenishment before again passing the aqueous liquid through the material. Preferred organic solvents are those which have a specific weight as different as possible from that of water, suitably the halogenated hydrocarbons (e.g. perchloroethylene) which may be mixed with a carrier co-solvent (e.g. phenol or phenol derivatives, chlorinated aromatic hydrocarbons, esters of aromatic acids with aliphatic alcohols or substituted naphthalene). Dyeing may be carried out below the boiling point of the solvent or under super-atmospheric pressure at a temperature below 130‹C. The dyestuffs used preferably have a solubility of 1 to 200 mg/litre in water and 1 to 30 g/litre in the solvent at 20‹C. Apparatus for carrying out the method comprises a dyeing vessel FA for receiving the fibrous material wound on bobbins, a dyestuff vessel FB in which the organic solvent solution of the dyestuff is prepared and a batch vessel AB in which the water is stored and heated at the beginning of the process. The three vessels are interconnected via a system of conduits 4, 5, 12 and 13. Valves 2, 3, 6, 9, 10 and 11 and a pump P. In operation water is charged into vessel AB and heated by heating coils 1 to the required temperature. The heated water is then passed via valve 2 and conduits 4 and 5 into the dying vessel FA which contains the fibres and at the same time organic solvent and dyestuff are placed into the vessel FB. Valves 9, 6, 10 and 11 are then set so that the contents of vessel FA passes to vessel FB wherein it passes upwardly in fine streams through the dye solvent, the valve 3 being reset so that the resulting dye solution, filtered at 15, is circulated through vessels FA, FB by the pump, so dyeing the fibre material.

Title: Improvements in and relating to organic diamino carbonates
Filed: 1961-12-22
Abstract: The invention comprises carbonate diamines of the formula <FORM:0990876/C2/1> wherein the groups R are identical or different and represent substituted or unsubstituted divalent aliphatic, aromatic, alicyclic or heterocyclic groups, and their salts with mineral acids.  Numerous compounds of the invention are specified. The compounds are prepared by reacting an appropriate hydroxy amine salt in an inert normally liquid reaction medium with phosgene at a temperature which does not exceed the temperature at which the salt dissociates, and recovering the carbonate diamine dihydrochloride product, if desired converting the salt into the base.  Specified solvents are aromatic and cycloaliphatic hydrocarbons, chlorinated aromatic and aliphatic hydrocarbons, dialkyl ketones and tetramethylene sulphone.  Examples are given. In Example 1 ethyl chloroformate is present in the reaction mixture, its function being to react with 2-amino-ethanol hydrochloride to give ethyl 2-aminoethyl carbonate hydrochloride which then reacts with 2-aminoethanol to give bis (2-aminoethyl) carbonate hydrochloride and ethanol; the ethanol is reconverted to ethyl chloroformate by reaction with the phosgene. Examples 3 and 4 describe the reaction of p-nitrophenol with phosgene to give bis (4-nitrophenyl) carbonate which is then hydrogenated to bis (4-aminophenyl) carbonate dihydrochloride. It is stated that when monoethanolamine hydrochloride is treated with phosgene at temperatures above 95 DEG C., 2-chloroethylamine hydrochloride and 1- or 2-chloroethylisocyanate are obtained, probably by an intramolecular reaction of the intermediate 2-aminoethyl chloroformate hydrochloride or by the direct action of by-product hydrogen chloride on the starting material.  It is also stated that dioxane or the dimethyl ether of ethylene glycol give 2-chloroethylisocyanate on treatment with phosgene.

[Also in Division H3] A circuit for the generation of working pulses in an electro-erosive metal working machine comprises a controlled four-layer triode 9 for pulsing the working gap 6 of the machine and a quenching circuit 5 for quenching pulses from the triode 9. A source 1 of D.C. voltage supplies a charging circuit 4, a quenching circuit 5, and a working circuit 3, four-layer triodes 9 and 11 in the working and charging circuits being simultaneously fired by a conventional pulse generating system (not shown). On firing, a capacitor 12 is charged through the conducting triode 11, the triode being quenched as the control current reverses. The capacitor discharges when a four-layer triode 14 in the quenching circuit 4 is fired, this being at the end of the prescribed duration of a pulse. The discharge quenches the triode 9, which became conducting as a discharge was initiated across the gap 6, by means of coupled inductors 13 and 8. A non-linear resistor 15, such as a selenium rectifier, diverts overvoltages to prevent overloading of the triodes, an overvoltage either being directed through a resistor 16 or being used to create a potential peak in the circuit 3 by means of a diode 17 and resistor 18. A number of such circuits can be coupled in parallel, the resulting pulsing of the gap 6 allowing a roughing operation (when the triodes are operated in phase) or a finishing operation (when they are operated in displaced phase).
