Abstract
The invention relates to a use of a blend comprising an amphiphilic amine, and an amphiphilic acid for increasing the electric conductivity of a lubricant based on a hydrocarbon oil. The invention further relates to a method for increasing the electric conductivity of a lubricant based on a hydrocarbon oil comprising the step of contacting the hydrocarbon oil with a blend comprising the amphiphilic amine, and the an amphiphilic acid; and to a lubricant based on a hydrocarbon oil comprising a blend comprising the amphiphilic amine which is a compound of formula (A1) and the amphiphilic acid which is selected from compounds (B1), (B3), (B4), (B5), fatty acids, or alkylbenzene sulfonic acids.
Claims11
A method for increasing the electric conductivity of a lubricant based on a hydrocarbon oil comprising the step of contacting the hydrocarbon oil with a blend comprising
- A) an amphiphilic amine, comprising an imidazoline group and a C6-32 hydrocarbon group, and
- B) an amphiphilic acid selected from compounds (B1) or (B3),
- where x is from 11 to 13 and n from 2 to 15, and wherein the lubricant comprises 20 to 1000 ppm of the amphiphilic amine, and 20 to 1000 ppm of the amphiphilic acid.
A lubricant based on a hydrocarbon oil comprising a blend comprising
- A) an amphiphilic amine which is a compound of formula (A1)
- and
- B) an amphiphilic acid which is selected from compounds (B1) or (B3),
- where x is from 11 to 13 and n from 2 to 15, wherein the lubricant comprises 20 to 1000 ppm of the amphiphilic amine, and 20 to 1000 ppm of the amphiphilic acid.
