Abstract: A process for the recovery of 1-nitroanthraquinone in a purified state from a nitroanthraquinone mixture containing it by treatment with a base in the presence of an initiator such as nitrite, halide, thiocyanate, alcoholate or phenolate ions in an organic solvent. A 1-nitroanthraquinone is obtained which is essentially pure or contains only small quantities of isomers and dinitroanthraquinones.

Abstract: Pure 1-nitroanthraquinone (I) is obtd. from nitroanthraquinone mixts. by treatment with a prim. and/or sec. amine or an alcoholate or phenate, in org. solvent. The amines are (cyclo)aliphatic, aryl aliphatic or satd. heterocyclic, e.g. ethanolamine, morpholine, in amt. 0.7-4 moles/mole (I). Pref. the alcoholate is an alcoholate of Na or K from lower alkanol or diol or the phenate is Na, K, NH4 phenate from a phenol (substd. by Cl, NO2, CH3). Solvent is 0.5-10 pts. wt. aliphatic or aromatic halogenated hydrocarbons etc. The treatment converts the by-prods. to soluble cpds. but (I) is unchanged. The prod. is used in dyes.

Abstract: 1339650 Propylene chlorohydrin BADISCHE ANILIN- & SODA-FABRIK AG 10 May 1971 [11 May 1970] 13961/71 Heading C2C Propylene chlorohydrin is continuously produced in aqueous solution by reaction of propylene with an aqueous solution of chlorine, the make-up water or the recycled reaction solution or a mixture thereof being loaded with gaseous and/or liquid chlorine in such an amount that that solubility limit is not exceeded, the propylene being metered at 2 to 20 atm. absolute and 10-80‹ C. into the chlorine-laden solution, the reaction mixture being allowed to react to completion in one or more parallel reaction tubes with turbulent flow in the same pressure range with a residence time of not more than ten seconds, the pressure then being released and the by-produets separated if desired, some of the propylene chlorohydrin being withdrawn as product and the remainder being recycled, the process being characterized by the introduction of the chlorine and propylene at a velocity of 2 to 100 m/sec. through one or more nozzles into a mixing zone extending in the direction of flow whose diameter is 1À5 to 50 times the mean outlet diameter of the liquid nozzles and whose length is 3 to 30 times its hydraulic diameter.

Abstract: To separate solid particles from liquids or gas, the liquid or the gas is passed through a coil, formed from one or more threads wound on a carrier. After subsequent washing and drying, the solid which has been filtered out during the filtration process is removed by unwinding the coil from the carrier, the latter consisting of a permeable hollow cylinder closed at both end faces by means of end plates, and provided with a feed orifice.
