Embodiment 1

[0034] The present embodiment discloses a preparation method of a special antistatic agent for light fuel oil, comprising the following steps:

[0035] 1: Preparation of imidazoline intermediates

[0036] Preparation of imidazoline intermediate: weigh 280 parts of octadecenoic acid (hexadecenoic acid), add 150 parts of triethylenetetramine (diethylenetriamine, tetraethylenepentamine), and 10 parts of xylene as water separating agent After 4-6 hours of reaction at 130-140°C, it was raised to 220-240°C for 4-6 hours of reaction. The infrared spectrum of its imidazoline (amide) intermediate is as follows figure 1 shown, 1600cm in the infrared spectrum -1 The peak is the characteristic peak of imidazoline.

[0037] 2: Preparation of imidazoline polyoxyethylene ether intermediate:

[0038] Weigh 100 parts of the imidazoline intermediate and add it into the autoclave, add 0.1 gram of potassium hydroxide, and pass through the propylene oxide addition reaction. The addition ratio...

Embodiment 2

[0047] The present embodiment discloses a preparation method of a special antistatic agent for light fuel oil, comprising the following steps:

[0048] 1: Preparation of imidazoline intermediates

[0049] Preparation of imidazoline intermediate: weigh 280 parts of octadecenoic acid (hexadecenoic acid), add 150 parts of triethylenetetramine (diethylenetriamine, tetraethylenepentamine), and 10 parts of xylene as water separating agent After 4-6 hours of reaction at 130-140°C, it was raised to 220-240°C for 4-6 hours of reaction.

[0050] 2: Preparation of imidazoline polyoxyethylene ether intermediate:

[0051] 100 parts of imidazoline intermediates were weighed into the autoclave, 0.1 g of potassium hydroxide was added, and ethylene oxide was added to the reaction vessel. The addition ratio of ethylene oxide is 1-1.2 times the mass of the imidazoline intermediate.

[0052] 3: Preparation of main agent of antistatic agent:

[0053]Weigh 450 parts of imidazoline polyoxyethyle...

Abstract

The invention provides a special antistatic agent for light fuel oil and a preparation method and application thereof. The preparation method of the special antistatic agent for light fuel oil comprises the following steps: weighing polycarbene acid, polyethylene polyamine and a water diversion agent, reacting for 4-6 hours at 130-140 DEG C, heating to 220-240 DEG C, and reacting for 4-6 hours to prepare an imidazoline intermediate; weighing the imidazoline intermediate, adding the imidazoline intermediate into a high-pressure reaction kettle, adding potassium hydroxide, and introducing epoxypropane for addition reaction to obtain an imidazoline polyoxyethylene ether intermediate; weighing the imidazoline polyoxyethylene ether intermediate, alcohol and sodium chloroacetate, and reacting at 80-100 DEG C for 4-6 hours to obtain an antistatic agent main agent; and weighing the antistatic agent main agent, the T551 metal deactivator, the stable synergist and the solvent oil to obtain the special antistatic agent for the light fuel oil. After the antistatic agent is added into fuel oil, the conductivity of the fuel oil can be improved, excessive accumulated static electricity is eliminated, and electrostatic hazards are solved.

Description

technical field [0001] The invention relates to a fuel oil antistatic agent technology, in particular to a special antistatic agent for light fuel oil, a preparation method and an application. Background technique [0002] In recent years, with the increasingly severe environmental problems, my country's environmental protection standards have become more and more stringent. Since the implementation of the National V fuel quality standards in 2018, the quality of oil products has been continuously improved. The main components of fuel oil and petroleum products are hydrocarbons. Compounds are poor conductors of electricity. The improvement of fuel oil standards is mainly to reduce harmful nitrogen, sulfur and other elements in fuel oil. The sulfur, nitrogen and other elements are removed by refining and other methods of fuel oil, which makes the electrical conductivity of fuel oil worse. The friction between the pipeline and the inner wall of the storage container is very ea...
