Claims
- 1. An oil-dispersible, water-based fuel oil additive comprising:
- (A) an aqueous metal-salt solution selected from the group comprising:
- 1. an alkaline-earth metal salt from the II-A group of the periodic table of the elements, or
- 2. a transition-metal salt;
- (B) a cationic quaternary water-soluble surfactant having an alkyl group, exclusive of the quaternizing agent of from 8-21 carbon atoms;
- (C) a solubilizing agent selected from the group consisting of alkylene glycol mono and di C.sub.1 -C.sub.4 alkyl ethers; and
- (D) a stabilizing agent selected from the group consisting of C.sub.1 -C.sub.3 alkyl alcohols; said fuel oil additive being capable of remaining in stable dispersion in a fuel oil.
- 2. The oil dispersible, water-based fuel additive of claim 1 which contains:
- (A) 75-99% by weight of an aqueous metal salt solution containing from 15% by weight to the limit of solubility of the designated metal salt;
- (B) 0.1-10% of the cationic quaternary surfactant;
- (C) 0.5-15% by weight of the solubilizing agent; and
- (D) 0.1-10% by weight of the alkyl alcohols with the provisio that the weight ratio of solubilizing agent to surfactant be at least 2:1.
- 3. The oil dispersible, water-based fuel additive of claim 1 wherein the metal salt solution is selected from the group consisting of aqueous solutions of the chloride sulfate and nitrate salts of magnesium, calcium, manganese, copper and aluminum.
- 4. The oil dispersible, water-based fuel additive of claim 1 wherein the cationic quaternary surfactant is an alkyl dimethyl benzyl ammonium chloride, such alkyl group containing from 8-21 carbon atoms.
- 5. The oil dispersible, water-based fuel additive of claim 1 wherein the solubilizing agent is diethylene glycol n-butyl ether.
- 6. A fuel oil containing a slag reducing amount of an oil dispersible, water-based fuel additive comprising:
- (A) an aqueous metal-salt solution selected from the group comprising:
- 1. an alkaline-earth metal salt from the II-A group of the periodic table of the elements, or
- 2. a transition-metal salt;
- (B) a cationic quaternary water-soluble surfactant having an alkyl group, exclusive of the quaternizing agent of from 8-21 carbon atoms;
- (C) a solubilizing agent selected from the group consisting of alkylene glycol mono and di C.sub.1 -C.sub.4 alkyl ethers; and
- (D) a stabilizing agent selected from the group consisting of C.sub.1 -C.sub.3 alkyl alcohols; said fuel additive after being added to the fuel oil remaining in stable dispersion in such fuel oil.
- 7. The fuel oil of claim 6 wherein the oil-dispersible, water-based fuel additive comprises:
- (A) an aqueous metal-salt solution selected from the group comprising:
- 1. an alkaline-earth metal salt from the II-A group of the periodic table of the elements, or
- 2. a transition-metal salt;
- (B) a cationic quaternary water-soluble surfactant having an alkyl group, exclusive of the quaternizing agent of from 8-21 carbon atoms;
- (C) a solubilizing agent selected from the group consisting of alkylene glycol mono and di C.sub.1 -C.sub.4 alkyl ethers; and
- (D) a stabilizing agent selected from the group consisting of C.sub.1 -C.sub.3 alkyl alcohols.
