Embodiment 1

[0050] Example 1: Add 26.23g of 6-aminocaproic acid, 12.38g of diethylenetriamine, and 50ml of xylene into a 250ml four-necked bottle as a solvent and a water-carrying agent. React at 140-160°C for 4 hours to remove the water generated in the reaction, react at 190-210°C for 2 hours to remove the water generated in the reaction, and then distill under reduced pressure for 1 hour to remove unreacted raw materials, and then obtain brown viscous liquid diethylene Triamine imidazoline.

Embodiment 2

[0051] Example 2: 26.23g of 6-aminocaproic acid was added to a 250ml four-neck flask, 25.07g of triethylenetetramine (purity of 70% by mass) was added, and 50ml of xylene was added as a solvent and a water-carrying agent. React at 140-160°C for 5 hours to remove the water generated in the reaction, react at 190-210°C for 3 hours to remove the water generated in the reaction, and then distill under reduced pressure for 1 hour to remove unreacted raw materials, and then obtain brown viscous liquid triethylene Tetraamine imidazoline.

Embodiment 3

[0052] Example 3: Add 26.23g of 6-aminocaproic acid, 22.72g of tetraethylenepentamine, and 50ml of xylene into a 250ml four-necked bottle as a solvent and a water-carrying agent. React at 140-160°C for 6 hours to remove the water generated in the reaction, react at 190-210°C for 2 hours to remove the water generated in the reaction, and then distill under reduced pressure for 1 hour to remove unreacted raw materials, and then obtain brown viscous liquid tetraethylene Pentaamine imidazoline.

[0053] All target compounds were determined by Spectrum One infrared spectrometer to have imidazole rings in the synthesized compounds. The C, H, and N element analysis results of the additives are shown in Table 1. From the elemental analysis results in Table 1, it can be seen that the measured values ​​of C, H, and N elements of all target compounds are basically consistent with the theoretical values ​​determined according to the molecular formula, and the absolute error is within the ...

Abstract

The invention relates to a fatty acid derivative containing an imidazoline group and a synthesis process and the application of the fatty acid derivative. The fatty acid derivative is synthesized by taking 6-aminocaproic acid as a raw material, reacting with diethylenetriamine/triethylene tetramine/tetraethylenepentamine, and using xylene as an azeotropic agent, wherein the synthesis product mainly comprises diethylenetriamine imidazoline/triethylene tetramine imidazoline/tetraethylenepentamine imidazoline. The operation is simple, the yield is high, and the reaction condition is easy to control. The fatty acid imidazoline derivative of the product can be used to prepare a water-based lubricant, a corrosion inhibitor and the like.

Description

technical field [0001] The invention belongs to the field of organic chemical industry, and relates to fatty acid derivatives containing imidazoline groups and a synthesis process thereof. The water-based lubricant prepared by the compound is suitable for use as water-based cutting fluid in the cutting industry, and is suitable for YG8 hard oil in an acidic environment. Alloys have a corrosion inhibitory effect. Background technique [0002] Lubricants are widely used in industry. Lubricants prolong the life of machines and machinery and reduce the loss of energy consumption. Under certain conditions, relative motion is only possible in the presence of lubricant. There are four types of lubricants: liquid, semi-solid, solid, and gas, commonly referred to as lubricating fluids, greases, solid lubricants, and gas lubricants. The main and most commonly used lubricants are liquid lubricants, namely lubricating oil and water-based lubricants. [0003] The main components of lu...
