    摘要: Oils for metal processing (e.g. oils for cutting operations) are typically aqueous emulsions, and the emulsifiers for these processing oils should have lubricating bacteriostatic/bactericidal, and corrosion-inhibiting properties. Suitable emulsifiers should comprise the following components:(A) about 30 to 50, preferably 40 to 45, weight % of a chlorinated paraffin sulfonate in admixture with a partially chlorinated paraffin;(B) about 15 to 30, preferably 20 to 25, weight % of at least one alkylsulfonamide/carboxylic or alkylsulfonamide/aminocarboxylic reaction product or a salt thereof;(C) about 15 to 20, preferably 12 to 17, weight % of a surface-active compound of the formulaR(CH.sub.2 CH.sub.2 O).sub.n H in which n is from 3 to 12, and R is C.sub.10 -C.sub.22 -alkanoyloxy or -alkenoyloxy, C.sub.8 -C.sub.22 -alkoxy or -alkenoxy, C.sub.6 -C.sub.16 -alkylphenyl or -alkylnaphthyl, or mono-, di- or tri-C.sub.8 -C.sub.22 -alkyl- or -alkenylamine; and(D) about 15 to 25 weight % of a mono- or di-ethanolamine C.sub.12 -C.sub.20 aliphatic carboxylic acid reaction product.

    摘要: A process for removing sulfuric acid from the reaction mixture obtained in the sulfoxidation of paraffins, which comprises adding an organic amine sulfate to the reaction mixture and removing the phase consisting of water and sulfuric acid which thereby separates out, adding to the remaining phase containing alkanesulfonic acid and alkanesulfonic acid amine salt an amount of an alkali metal hydroxide sufficient to convert the alkanesulfonic acid and the alkanesulfonic acid amine salt into the alkali metal alkanesulfonate, the organic amine being liberated, removing the paraffin from this mixture, together with the free organic amine, by steam distillation, removing the free organic amine from the paraffin by extraction with sulfuric acid and employing the resulting organic amine sulfate again at the start of the whole process for removing the sulfuric acid.

    摘要: Pure toluene-4-sulfonic acid is obtained without forming any by-products by sulfonating toluene with sulfuric acid at an elevated temperature, separating a first batch of toluene-4-sulfonic acid hydrate, washing it free of isomers with sulfuric acid, combining the mother liquor and the washing effluent, heating them, allowing a second batch of hydrate to crystallize and, optionally, working up the final mother liquor by hydrolizing the toluene sulfonic acids therein and recycling the toluene so formed and the sulfuric acid after concentrating it to its initial strength.
