Abstract: The invention relates to a process for removing carbon black from an aqueous suspension obtained by washing a gas containing carbon black with water. To this end, a gas stream comprising hydrocarbons and at least one inert gas is introduced into a suspension having a solids content of from 0.5 to 4% by weight, at a temperature of from 10 DEG to 80 DEG C. In so doing, the carbon black agglomerates and collects on the surface of the suspension water from which it is separated, for example by skimming it off. The gas stream is produced by passing inert gas over the separated carbon black containing the hydrocarbons and heated to 200 DEG to 400 DEG C., the carbon black being converted into a dry, free-flowing material.

Abstract: A detergent containing 5 to 50% by weight of at least one surfactant, 0.5 to 60% by weight of a matrix substance and also standard laundry aids, contains as matrix substance an amorphous, low-water sodium disilicate having a water content of 0.3 to 6% by weight which has preferably been produced by partial dehydration of commercially available powdered amorphous sodium disilicate having a water content of 15 to 23% by weight.

Abstract: The invention provides stabilized pulverulent red phosphorus comprising a homogeneous blend of red phosphorus particles with a size of at most about 2 mm, aluminum hydroxide and a further metal hydroxide as oxidation stabilizers, wherein the metal hydroxide is lead hydroxide. The homogeneous blend contains aluminum hydroxide and lead hydroxide in a total proportion of about 0.1 to 6 weight %, based on the quantity of red phosphorus, the aluminum hydroxide and lead hydroxide, calculated as Al2O3 to PbO, being used in a quantitative ratio of about 0.5 to 2.0.

Abstract: In a process for making free flowing compsns. based on anhydrite (I), an activator (II), a liquifying agent consisting of a sulphite- or sulphonic acid modified amino resin (III) based on an amino-s-triazine with >=2 NH2 gps., a wetting agent (IV) and water, the (II), (III) and (IV) are first completely dissolved in the water and the resulting soln. is introduced into a mixing zone contg. the (I). The prods. are pumpable, self-levelling fluid materials which are esp. useful for levelling floors prior to the laying of parquet or tiles. By dissolving the (II), (III) and (IV) in water prior to mixing with the (I), smaller amts. of (III) can be used than in prior art materials in which the (III) is mixed with the (I) before adding the water, without affecting the fluidity or strength of the prod. The amt. of (III) used is 0.01-0.5 wt.% (on I) compared with 0.5-10 wt.% previously.

Abstract: For purifying dye effluents by means of chemical flocculants, a chlorinating agent is added in a first stage to the dye effluent, a divalent iron salt is then added and subsequently the pH is adjusted to a value between 5.0 and 7.0 and the precipitated iron hydroxide is removed. This process allows in general a virtually complete removal of the dye from the effluent. At the same time, the COD and BOD5 value are normally greatly reduced, whereby a substantial release of the biological water treatment plant is effected.
