Abstract: 1,167,592. Textile treating apparatus. PEDER MORTENSEN A.S. 21 Jan., 1967, No. 3238/67. Heading D1L. The operation of a closed wind beck in which textile goods are treated in a liquid at elevated temperature is characterised in that there is provided at least during a part of the treatment .period, means for adjustment of the heat supply to the treatment liquid and for removal of vapour from the space above the liquid so that a controlled vapour production takes place in the liquid. The vapour removal can be controlled dependent on a sensing of the temperature in the liquid as compared with a desired temperature and can be done by causing the vapour to flow out from the container and/or by condensation of the vapour. The apparatus shown comprises a container 1 having domed end walls 2, 3 with a liquid container within, formed by end walls 4, 5 and the lower portion of container 1. False bottom plates 6, 7, 8 and 9 are provided within the container and a battery of steam pipes 10 for heating the liquid is located beneath the plate 8. The material, in rope form, is circulated through the iquid by a main reel 13-16 having radially adjustable longitudinal members, and a secondary reel 18. Separating arms 23 are provided between adjacent pieces of material which arms form parts of suitable stop mechanisms. Vapour can be released from the space above the liquid by a controlled valve or can be condensed by means of cold surfaces e.g. the surfaces of pipes through which cold liquid can be caused to flow. Programme control apparatus (Fig. 3 not shown) may be used to control the heating of the liquid and/ or the removal of vapour according to requirements. As an alternative vapour may be sucked out of the container and the treatment is at below atmospheric pressure.

Title: Production of oil-modified alkyd resins
Inventor: SPIVEY ARTHUR MARSHALL
IPC: C08G63/46
Filed: 1964-01-27
Abstract: An oil-modified alkyd resin is derived from phthalic anhydride, a polyhydric alcohol and a modifying oil comprising at least 50 wt. per cent of cod liver oil.  When the oil length exceeds 45% an a ,b -unsaturated dicarboxylic acid or anhydride is also present; when the oil length is less than 45% a monocarboxylic acid or anhydride is added; between 40 and 50%, however, the additional components are not essential.  The polyhydric alcohol may be glycerol, pentaerythritol or trimethylolethane, and may include some diol, e.g. diethylene glycol or propylene glycol.  Suitable a ,b -unsaturated acids are fumaric, maleic, citraconic and mesaconic acids, and suitable monocarboxylic acids are benzoic, toluic and t-butylbenzoic acids, or aliphatic acids containing up to 10 C-atoms, e.g. caproic and capric acids. Preferably the cod liver oil or oil mixture is first alcoholysed with the polyhydric alcohol, usually in the presence of a catalyst, e.g. Ca(OH)2, and is then condensed with the rest of the starting materials, including any further polyhydric alcohol required. Usually the amounts used of the a ,b -unsaturated acid, or of the monocarboxylic acid, do not exceed 15% or 20% by weight respectively of the phthalic anhydride.  The amounts increase as the oil length departs from the 45% value.  The polyhydric alcohol is usually in excess, there preferably being 1.1-1.3 OH groups per carboxyl group in free or anhydride form.  The condensation may be performed with reactants fused or in solution, e.g. in xylene, preferably at 200-300 DEG  C.  The product may have an acid value below 10 or 15, and be soluble in solvent naphtha and xylene.  The cod liver oil may be mixed with up to 50 wt. per cent of other marine or vegetable oils, and other dicarboxylic acids or anhydrides may be included, e.g. adipic or sebacic acid.  In examples an alkali-refined cod liver oil is heated with glycerol and Ca(OH)2 and is then heated with [1] phthalic anhydride, glycerol and benzoic acid, [2], [3] phthalic anhydride, maleic anhydride and xylene, to give alkyds of oil lengths 33%, 55% and 70% respectively.  These are milled with TiO2 in xylene to give paints.  The paints from resins [1] and [2] are stove-dried, that fro [3] is airdried, after addition of cobalt and lead naphthenate driers.

Patent GB-372301-A (GB)
Title: The manufacture of new carbazole compounds
IPC: C07D209/88
Filed: 1931-02-03
Abstract: Azo dyes are made in substance or on the fibre by coupling an N-substituted 2-hydroxycarbazole-3-carboxylic acid arylide of the formula <FORM:0372301/IV/1> where R = a hydrocarbon radicle and R an aromatic or heterocyclic nucleus with a diazotized aromatic or heterocyclic amine free from solubilizing groups.  In examples (1) cotton impregnated with N-methyl-2-hydroxycarbazole-3-carboxylic acid-p-chloranilide is developed with diazotized m-chloraniline. Other coupling components specified are the o-anisidide, anilide and o-toluidide of the N-methyl derivative and the o-toluidide of the N-ethyl derivative and other diazo components mentioned are 3- or 4-nitraniline, 4- or 6-chloro-2-toluidine, 5-nitro-2-anisidine, o- or m-aminoazotoluene, 1-amino-4-benzoylamino-2 : 5-diethoxybenzene, 5-nitro-2-toluidine, 4-amino-2 : 5 - dimethoxy-4<1> - nitro-1 : 1<1> - azobenzene and 2 : 5-dichloraniline.  N-substituted 2-hydroxycarbazole-3-carboxylic acid arylides are made by heating an N-substituted 2-hydroxycarbazole-3-carboxylic acid with an aromatic or heterocyclic primary amine in an inert solvent in the presence of phosphorus trichloride.  In an example, N-methyl-2-hydroxycarbazole-3-carboxylic acid and p-chloraniline are heated with toluene and phosphorus trichloride.  The N-phenyl-2-hydroxycarbazole-3-carboxylic acid o-toluidide is specified.  N-substituted-2-hydroxycarbazole- 3 - carboxylic acids are made by treating the alkali metal salts of N-substituted 2-hydroxycarbazoles with CO2 under pressure and at an elevated temperature, or by similarly treating the alkali metal salts or the free hydroxycarbazoles in presence of an alkali metal carbonate. Examples are given.  N-substituted 2-hydroxycarbazoles are made from the corresponding 2-alkyloxycarbazoles by splitting up the 2-alkyloxy group by known methods such as by heating in an inert solvent with the addition of a metal halogenide used in the Friedel-Crafts reaction, or by heating in a solvent with the addition of a hydrohalic acid, or by melting with caustic soda.  In an example, N-methyl-2-ethoxycarbazole is heated with AlCl3 in benzene to give N-methyl-2-ethoxycarbazole: the same product is obtained by heating the alkoxy derivatives with a solution of gaseous hydrochloric acid in glacial acetic acid or by fusion with caustic soda.  The N-ethyl derivative is similarly prepared.  N-substituted 2-alkoxycarbazoles are made by alkylating 2-hydroxycarbazoles with dialkylsulphates in caustic soda or with halogen alkyls in alcoholic solution in presence of an acid binding agent and introducing the hydrocarbon radicle into the imino group by the action of dialkyl sulphates in excess in an inert solvent in presence of an acid binding agent or in the case of an aromatic hydrocarbon, for example, the introduction of a phenyl group, by heating with iodobenzene, potash and copper powder in nitrobenzene.
