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.

Quaternary crosslinked products obtained by reacting triethanolamine condensates of the formula ##STR1## wherein n is an integer of from 1 to 3, with xylylene dichloride and their use as demulsifiers for oil-water emulsions, as lubricants and as auxiliaries in the paper industry.
摘要:
Diaminophenyl ureas of the formula ##STR1## in which R is an inert substituent, are obtained from the corresponding dinitrophenyl urea by way of reduction, especially catalytic hydrogenation. Through a cyclization process, while splitting off ammonia, these ureas yield the corresponding aminobenzimidazolones, advantageously without an intermediate isolation of the diaminophenyl ureas.
摘要:
The present invention relates to a process for the preparation of compounds of the formula 1 ##STR1## by reacting a secondary acid amide of the formula 2 ##STR2## with an acid chloride of the formula 3 ##STR3## in the presence of N,N-diisopropyl-N-ethylamine. R.sup.1, R.sup.2 and R.sup.3 are alkyl or alkenyl radicals, if required also aryl radicals. The compounds of the formula 1 are suitable for use as insecticides or bleach activators.
摘要:
The present invention relates to a process for the formaldehyde-free easy care finishing of cellulose-containing textile material by treating the cellulose-containing textile material with an aqueous liquor containing a polycarboxylic acid crosslinker and a crosslinking catalyst, then drying and heat treating, which comprises using boric acid or a derivative thereof as the crosslinking catalyst.

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.
