Potassium oleate can be used as lubricant, detergent, emulsifier, antirust agent, etc.; it can also be used in hand sanitizer, latex, lubricating cutting oil, paint remover, textile, leather, etc. Its application examples are as follows:
1. Prepare a sort of antifungal agent for finishings, including triethanolamine, tea polyphenols, benzotriazole, potassium oleate, bactericide, hydrogen peroxide, water, and the mass parts of each component are: triethanolamine 6- 9. Tea polyphenols 1-3, benzotriazoles 5-7, potassium oleate 3-8, fungicides 2-6, hydrogen peroxide 5-7, water 10-14. Preferably, the antifungal agent for coverings is defined because: the parts by mass of the components of the antifungal agent for finishings are: triethanolamine 6, tea polyphenol 2, benzotriazole 7, potassium oleate 7. Fungicide 5, hydrogen peroxide 5, water 12.
2. Preparation of multi-functional microemulsion gasoline and diesel combustion aids. It is composed of auxiliary soft water, C5-9 fatty alcohol, oleic acid, sodium hydroxide, isopropanolamine and potassium oleate, and is characterized in that the weight ratio of the above-mentioned various components is 20-35% of auxiliary soft water; C5 -9 fatty alcohol 20-30%; oleic acid 40-50%; sodium hydroxide 1-2%; isopropanolamine 2-3%; potassium oleate 1-2%.
Each component is fully stirred and mixed in a container to prepare a multi-functional micro-emulsified gasoline and diesel combustion aid. The multi-functional microemulsion gasoline and diesel combustion aid has the characteristics of high stability, wide applicability, energy saving, environmental protection and non-corrosiveness. At room temperature, the weight ratio of combustion improver to gasoline or diesel is 15% to 85%, and the micro-emulsion gasoline or diesel composite fuel is made. It has a transparent appearance, good stability and high thermal efficiency, and can be widely used in gasoline. Diesel internal combustion engines are used as environmentally friendly fuels.
3. Preparation of anionic viscoelastic surfactant-based gels. Based on the viscoelastic surfactant system (VES.Y) formed by potassium oleate and potassium chloride, in VES. Add cross-linking agent (N,N-methylenebisacrylamide) and initiator to Y, under the protection of N gas, keep the temperature at 60°C for 24 h, and polymerize to obtain anionic viscoelastic surfactant gel (VES. G). To VES. G and VES. The performance of Y system, such as temperature resistance, organic hydrocarbon resistance, gel breaking and damage to reservoir, was evaluated indoors.
The results showed that VES. The temperature resistance and shear resistance of the G system have been greatly improved, and the sensitivity to organic hydrocarbons has been significantly weakened. After breaking the gel, VES. G system performance and VES. The Y system is basically the same; and it is confirmed by the core flow experiment, VES. The G system has no damage to the reservoir, and the permeability retention rate is >99%.
