    Abstract: An antifoaming agent comprises a tributyl and/or triamyl phosphate and 0.1 - 20% of the active ingredients, of one or more C14-C22 saturated monocarboxylic acids. The phosphate ester may be of a normal or branched chain butyl or amyl group, isobutyl being preferred. Specified acids are normal myristic, palmitic, stearic, arachidic and behenic acids. Solvents and diluents e.g. low molecular weight alcohols, e.g. n-propanol, glycols and glycol ethers may also be present in the composition. The composition may be used in an amount of 0.02 - 0.05% of the liquid to be treated, in Examples an aqueous liquid containing an alkylbenzene sulphonate possibly containing Na2CO3 or an ethylene oxide-isooctylphenol adduct. The composition may be poured or sprayed onto foaming liquid or added prior to foaming. They may be incorporated into detergents, cleaning and wetting agents, textile treating agents e.g. kier boiling assistants and mercerising assistants and plant protection ingredients. They are particularly active in the presence of ions producing hardness e.g. Mg and Ca ions. Comparative examples disclose mixtures comprising caprylic, lauric and oleic acids and tri-n-propyl, i-octyl, i-nonyl and i-decyl phosphates.

    Abstract: Fluorobins of formula in which R1 and R2 are H, halogen, alkyl or alkoxy and rings A and/or E may have further fused rings are quaternized on one or more ring nitrogen atoms by heating at 150-200 DEG C. with alkyl- or aryl-sulphonic acid esters or other alkylating, cycloalkylating or aralkylating agents such as dialkyl sulphates or p-toluene-sulphonates, with or without addition of an inert diluent. Specified compounds are fluorobin and 2,9(10)-dichloro-, -dimethyl- or -dimethoxy-fluorobins quaternized with dimethyl sulphate; and fluorobin and 2,3,9,10-dibenzofluorubin quaternized with diethyl sulphate. U.S.A. Specification 2,495,202 is referred to.ALSO:Cotton materials mordanted with tannic acid, leather and acrylonitrite polymers are dyed or printed with a composition characterised by the presence of a fluorubin of formula which is quaternised with alkylating, cycloalkylating or aralkylating agents on one or more ring nitrogen atoms and in which R1 and R2 are H, halogen, alkoxy or alkyl; rings A and/or E may have further fused rings. Other specified ingredients of dyebaths are sperm oil alcohol/80 mols ethylene oxide reaction product, acetic acid and optionally (a) sodium sulphate, sodium bicarbonate, sodium chloride, potassium bromide or potassium iodide, or (b) tannic or phosphotungstic acid; sulphonated sperm oil alcohols and quaternary amines of palm oil are also mentioned. Other specified ingredients of printing pastes are crystal gum thickening, thiodiethylene glycol, tartaric acid, and sodium sulphate, acetic acid and the sodium salt of the sulphate of sperm oil alcohol/80 moles ethylene oxide reaction product. U.S.A. Specification 2,495,202 is referred to.

    Abstract: 1,156,745. Substituted ureas. BADISCHE ANILIN- & SODA-FABRIK A.G. 11 Nov., 1966 [12 Nov., 1965], No. 50623/66. Heading C2C. N - Phenyl - N 1 - alkoxy - N 1 - alkylureas are prepared by reacting a 5-30 wt. per cent aq. hydroxylamine solution with a phenyl isocyanate in water in presence of a water-insoluble solvent, separating the latter without application of heat, and alkylating the reaction product. Examples describe the preparation of N-phenyl- and N - p chlorophenyl - N 1 - methoxy - N 1 - methylureas.
