Abstract: Trialkanolamine polyethers, obtainable by condensing tri-alkanolamine(s) in the presence of (hypo)phosphorus acid, are useful as demulsifiers in 0/W emulsion. The trialkanolamines are of formula (I), where R1-R3 = 1,2-(2-4C)alkylene.

Abstract: A fuel for Otto engines contains a small amt. of cpds. of formula (I). In (I) R = polyisobutylene gp. with mol. wt. 500-5,000; R1 = H, Me or Et; m = 0 or 1. Pref. the fuel contains 50-5000 ppm of (I), and opt. other fuel detergents, antifreeze agents, corrosion inhibitors and/or antioxidants. In (I), the mol. wt. of R is 800-1500. (I) are prepd. by hydroformylation of a polyisobutylene R', followed by hydrogenative amination and reaction with ethylene oxide, propylene oxide or butylene oxide in presence of water. (R' = olefin with 1 fewer H than the gp. R). ADVANTAGE - (I) disperse oil sludge, in addn. to acting as carburettor detergents and valve cleaners.

Abstract: Use of copolymers obtainable by free-radical copolymerisation of (a) C8-C40-monoolefins with (b) ethylenically unsaturated C4-C8-dicarboxylic anhydrides in the manner of a mass polymerisation at from 80 to 300 DEG C to form copolymers having molecular weights of from 500 to 20,000 g/mol, subsequent solvolysis of the anhydride groups of the copolymers and at least partial neutralisation in an aqueous medium with bases of the carboxyl groups formed in the course of the solvolysis and which are present in the form of aqueous dispersions or solutions, as agents for waterproofing leathers and pelt furs.

Abstract: 1. A glycol-based coolant mixture which is free of nitrites and phosphates, containing a) 1 - 5% by weight of an alkali metal salt of acid II see diagramm : EP0283806,P7,F1 where R is a -CH2 -, see diagramm : EP0283806,P7,F2 see diagramm : EP0283806,P7,F3 or CH2 CH2 CH2 group, b) 0.1 - 1% by weight of a silicate of the general formula III (MO)q SiO4-q/2 where M is an alkali metal and q is from 0.4 to 4, c) 0.01 - 0.2% by weight of a silicate stabilizer, d) 0 - 0.5% by weight of an alkali nitrate, e) 0.05 - 0.2% by weight of benzotriazole or tolutriazole, f) 0.5 - 2% by weight of borax, and g) 0.05 - 1% by weight of NaOH, all the percentages being based on the glycol present in the coolant mixture.
