Abstract
Motor fuels or fuel oils in the form of an emulsion contain water, an emulsifier and optionally an alcohol, the emulsifier being at least 25% by weight of a compound of the general formula: ##STR1## wherein R.sub.1 and R.sub.4 are saturated or unsaturated, straight-chain or branched hydrocarbon aliphatic radicals with 4 to 24 C atoms, R.sub.4 can also be an alkylphenyl radical of 1 to 18 C atoms in the optionally branched, alkyl chain or H; R.sub.2, R.sub.3 and R.sub.5 represent a methyl group or H, n and m is a number from one to 20 plus z from 0 to 15, and X is an acid radical --COO.sup.(-) or --OCH.sub.2 COO.sup.(-). The emulsions are especially stable and of low viscosity.
Claims21
In a water/oil emulsion comprising combustion effective amounts of water, a motor fuel useful for internal combustion engines or a fuel oil and an emulsifier, the improvement wherein the emulsifier comprises at least 25% by weight of a compound of the formula:
- ##STR4## wherein R.sub.1 and R.sub.4 each independently is alkyl or alkenyl of 4 to 24 C atoms, and R.sub.4 can also be alkylphenyl of 1 to 18 C atoms in the alkyl portion or H;
- R.sub.2, R.sub.3 and R.sub.5 each independently is methyl or H;
- n plus m is a number from 1 to 20;
- z is 0 to 15;
- and X is --COO.sup.(-) or --OCH.sub.2 COO.sup.(-).
A method of lowering the viscosity of an emulsion of water, a motor fuel oil or a fuel oil, and an emulsifier, comprising using as at least 25% of said emulsifier, a compound of the formula:
- ##STR5## wherein R.sub.1 and R.sub.4 each independently is alkyl or alkenyl of 4 to 24 C atoms, and R.sub.4 can also be alkylphenyl of 1 to 18 C atoms in the alkyl portion or H;
- R.sub.2, R.sub.3 and R.sub.5 each independently is methyl or H;
- n plus m is a number from 1 to 20;
- z is 0 to 15;
- and X is --COO.sup.(-) or --OCH.sub.2 COO.sup.(-).
