Abstract: An aqueous solution of performic acid is produced by the reaction of an aqueous solution of formaldehyde with an aqueous solution of hydrogen peroxide in the presence of 0.3-30% with reference to the total weight of the anhydrous formaldehyde and hydrogen peroxide to be reacted, of an organic or inorganic acid or a salt thereof, e.g. sulphuric, phosphoric, formic, acetic, lactic, maleic, citric or tartaric acid, as a catalyst. The solution may be stabilized by the addition of tetrasodium pyrophosphate, magnesium silicate, magnesium phosphate, complex magnesium-alkali metal salts of nitrilotriacetic acid, ethylene diamine tetracetic acid or hexamethylene diamine tetracetic acid, acetamide, formamide, alkali metal, citrates, ammonium citrate or maleic anhydride. Specifications 656,938, 804,781 and 810,439 are referred to.ALSO:Protein-containing materials, e.g. wool, silk, leathers and hog's bristles, are bleached by treating them with a liquor having a pH value of 2-8.5 comprising aqueous performic acid solution which has been prepared by the reaction of aqueous formaldehyde solution and aqueous hydrogen peroxide solution in the presence of 0.3-30% with reference to the total weight of the anhydrous formaldehyde and hydrogen peroxide to be reacted, of an p organic or unorganic acid or a salt thereof, e.g. sulphuric, phosphoric, formic, acetic, lectic, citric, maleic and tartaric acids, as a catelyst. The bleaching solution may be stabilised by the addition of tetrasodium pyrophasphate, magnesium silicote, magnesium phosphate, complex magnesium-alkali metal salts of aminocarboxylic acids which have more than one carboxylic group to one basic nitrogen, e.g. nitrilotriacetic acid, ethylene diamine tetracetic acid or hexamethylene diamine tetracetic acid, acetamide, formamide, alkali metal citrates, ammonium citrate or maleic amhydride, and may be adjusted to the desired pH value by the addition of ammonium or sodium carbonate. The treating solution may also contain optical bleaches e.g. 4, 5-diphenyl imidazolene disulphonate softeners and wetting agents, e.g. an octa or nonyl phenol polyglycol ethers. When working with a long liquor the material may be introduced into the bleaching liquor at 40 DEG -50 DEG C. and treated for 2-4 hours at 50 DEG C. Piece goods may be treated by a batchwise or continuous padding method in which they are impregnated on a padding machine with the bleaching liquor, squeezed, rolled up, wrapped in a waterproof sheet and then left for 10-15 hours at 15 DEG -25 DEG C. or for 2 hours or less at temperatures of 50 DEG C or higher, or after impregnation are introduced at open width into a steamer where they are allowed to remain for a few minutes.

Abstract: Substituted 1,4-bis-styryl benzenes of the general formula: in which X and X1 stand for carboxylic ester groups or N-alkyl carboxylic amide groups, are prepared by reacting terephthaladehyde with an ester of a carbalkoxy-benzylphosphonic acid or with an ester of a halogenmethylbenzoic acid, with the aid of a triarylphosphine and an alkali alcoholate, and if necessary converting the ester groups of the products into amide groups. These substituted 1,4-bis-styryl benzenes are optical brightening agents (Group IV(c)). In Example 1, the methyl ester of p-chlormethylbenzoic acid is stirred with triphenylphosphine in dimethylformamide at 80 DEG C. for 3 hours; and then terephthalaldehyde followed by sodium methylate are added. The product is 1,4-bis-(para-carbmethoxy-styryl)-benzene, and this is converted, by heating it with diethanolamine, into 1,4-bis-(para-carbodiethanolamidostyryl)-benzene Example 8 refers to 1,4-bis-(meta-carbdiethanolamido-styryl)-benzene. Example 9 describes the preparation of a mixture of 1,4-bis-(para-carbethoxy-styryl) - benzene, 1,4 - bis - (metacarbmethoxy-styryl)-benzene and 1-(para-carbmethoxy-styryl) - 4-(meta1-carbmethoxy-styryl)-benzene, by reacting terephthalaldehyde with a mixture of meta- and para-carbmethoxy-benzyl-phosphonic acid diethyl ester. The mixture of 1,4-bis-styryl-benzene diesters is then reacted with diethanolamine. Example 19 states that 1,4-bis-(meta-carb-N-cyclohexylisopropanol-amidostyryl)-benzene is obtained by reacting 1,4 - bis - (meta-carbmethoxy-styryl)-benzene with N-cyclohexyl-iso-propanolamine. It is stated that X and X1 in the general formula may stand for COO.C2H4OH, and similar groups. Compounds wherein the hydrogen atoms of the hydroxy groups in both the amides and the esters are substituted by glycol ether groups are obtained by the reaction of the amides or esters with ethylene oxide or propylene oxide. Specification 813,539 is referred to.ALSO:Substituted 1, 4-bis-styryl benzenes of the general formula in which X and X1 stand for carboxylic ester groups or N-alkyl carboxylic amide groups, act as brightening agents for textiles, paper and leather. The brightening agent is preferably used in aqueous medium in amounts of about 0,0015 to 0.05% with reference to the weight of the substrate to be brightened. In Example 1, previously bleached cotton fabric is treated, for 20 minutes, in a liquor, at 50 DEG to 60 DEG C., containing 0,003 to 0,01 grams per litre of the compound having the structure and 5 grams per litre of sodium sulphate decahydrate, the liquor to fabric ratio being 50:1. After rinsing and drying, the fabric has a dazzling whiteness of good fastness to light and washing. Examples 5, 6 and 7 relate to the use of the same compound for brightening polycaprolactam fabric, yellowish paper, and soiled clothing, respectively. Example 8 describes the use of 1, 4-bis-(metacarbdiethanolamidostyryl)-benzene for brightening cotton fabric. For the preparation of the brightening agents, (see Group IV(b)). Specification 813,539 is referred to.

Abstract: Soaps, synthetic detergents and mixtures thereof in solid form, e.g. in cake, flake, needle and powder form, are stabilized against spotting and rancidity caused by heavy metal ions such as those of iron, nickel and copper by the incorporation of an additive which is substantially free from uncombined alkali metal hydroxide comprising (a) one or more polyhydric alcohols containing more than 4 hydroxyl groups, and (b) one or more complex-forming compounds containing the group where R1 and R2 each represent -C2H4OH or -CH2COOX, X being hydrogen or an alkali metal. The total of (a) and (b) preferably amounts to 0.05-5% by weight of the composition, and the weight ratio of (a) to (b) is 2:1 to 1:1. (a) is for example manitol, xylitol, or hydrogenated wood hydrolysate, but is preferably sorbitol, while (b) may be dihydroxyethylamino-acetic acid, iminodiacetic acid, nitrilotriacetic acid, hydroxyethylethylene diamine triacetic acid, ethylene diamine triacetic acid, 1:2-diaminocyclohexane tetracetic acid, N:N1-dihydroxyethyl-1:2-diaminocyclohexane-N:N1 -diacetic acid, 2-hydroxy-1:3-diaminopropane tetracetic acid, or tetrahydroxyethyl-1:2-diaminocyclohexane, but is preferably ethylenediamine tetracetic acid. Suitable detergents, in addition to soap, include alkyl sulphates or sulphonates, alkylglycol ether sulphates, alkylaryl sulphonates, fatty acid condensates, poly-glycol ethers of alkylphenols or fatty alcohols, or cationic active compounds. Cellulose ether carboxylic acids, cellulose ethers and esters, salts of polyacrylic and polymethacrylic acids, polyvinyl compounds such as polyvinylpyrrolidone, polyglycol ethers, fatty acid alkanolamides, triethanolamine, esters of polyhydric alcohols and glucosides, glucosides themselves and ethylene condensates of such esters and glucosides, potato flour, phosphates, silicates, sodium chloride and sulphate, talc, bentonite, titanium dioxide, paraffin wax, petroleum jelly, skin protectives, disinfectants, optical brighteners and dyestuffs may also be incorporated.
