Abstract
The present disclosure relates to a composition for corrosion inhibition in a fuel mixture. The present disclosure also relates to a method for preparing a composition for corrosion inhibition in a fuel mixture. The corrosion inhibitor of the present invention delivered excellent corrosion resistance, minimum dosage levels & good stability and miscibility which can be used for mitigating corrosion issues in neat Ethanol and Gasohol.
Claims14
A composition for corrosion inhibition in a fuel mixture, the composition comprising:
- 0.1-4 w/w % of an amine;
- 0.1-4 w/w % of a quaternary ammonium salt;
- 0.1-3 w/w % of an antioxidant;
- 30-60 w/w % of a polar solvent;
- and
- 30-60 w/w % of a hydrocarbon-based solvent,
- wherein the w/w % is based on the total weight of the composition.
A method for preparing a composition for corrosion inhibition in a fuel mixture, said method comprising:
- a) mixing 30-60 w/w % of a polar solvent, 0.1-3 w/w % of an antioxidant, 0.1-4 w/w % of a quaternary ammonium salt and 0.1-4 w/w % of an amine to obtain a first mixture;
- and
- b) mixing 30-60 w/w % of hydrocarbon-based solvent to the first mixture to obtain a corrosion inhibitor in a fuel mixture,
- wherein the w/w % is based on the total weight of the composition.
A fuel composition comprising:
- a fuel mixture, and
- 10 to 200 ppm of a composition comprising:
- 0.1-4 w/w % of an amine;
- 0.1-4 w/w % of a quaternary ammonium salt;
- 0.1-3 w/w % of an antioxidant;
- 30-60 w/w % of a polar solvent;
- and
- 30-60 w/w % of a hydrocarbon-based solvent,
- wherein the w/w % is based on the total weight of the composition.
Use of a composition comprising
- 0.1-4 w/w % of an amine;
- 0.1-4 w/w % of a quaternary ammonium salt;
- 0.1-3 w/w % of an antioxidant;
- 30-60 w/w % of a polar solvent;
- and
- 30-60 w/w % of a hydrocarbon-based solvent,
- wherein the w/w % is based on the total weight of the composition,
- as a corrosion inhibitor in a fuel mixture of ethanol and gasoline.
