Embodiment 1

[0031] The total weight part is 100 parts, the preparation method of this embodiment oil dispersant is as follows:

[0032] (1) Add marine fish oil and diethanolamine into a three-necked flask with a reflux condenser at a mass ratio of 1:4, and turn on the agitator.

[0033] (2) Then, the temperature of the three-neck flask was raised to 125° C., and 1.5 wt % catalyst KOH of the total amount of marine fish oil and diethanolamine was added, and the stirring was continued and the heat preservation reaction was continued until the amine value was no longer changed, and the reaction solution was obtained after cooling to room temperature.

[0034] (3) Add 2 times the mixed solvent formed by diethyl ether and chloroform (the volume ratio of the two is 1:1) to the reaction solution, stir thoroughly for 20 minutes; Glycerin and catalyst mixed solution; Then the organic solution in the separatory funnel is washed twice, and the solution located in the lower layer is separated each tim...

Embodiment 2

[0037] The total weight part is 100 parts, the preparation method of this embodiment oil dispersant is as follows:

[0038] (1) Add marine fish oil and diethanolamine into a three-necked flask with a reflux condenser at a mass ratio of 1:4, and turn on the agitator.

[0039] (2) Then, the temperature of the three-neck flask was raised to 125° C., and 1.5 wt % catalyst KOH of the total amount of marine fish oil and diethanolamine was added, and the stirring was continued and the heat preservation reaction was continued until the amine value was no longer changed, and the reaction solution was obtained after cooling to room temperature.

[0040] (3) Add 2 times the mixed solvent formed by diethyl ether and chloroform (the volume ratio of the two is 1:1) to the reaction liquid, and stir thoroughly for 20 min. Then transfer to the separatory funnel and let it stand overnight, separate the glycerol and catalyst mixed solution that is located in the lower layer; then, wash the fatty...

Embodiment 3

[0043] The total weight part is 100 parts, the preparation method of this embodiment oil dispersant is as follows:

[0044] The preparation of fish oil fatty acid diethanolamide is the same as in Example 1.

[0045] Mix 30 parts by weight of fish oil fatty acid diethanolamide, 13 parts by weight of penetrant JFC, 15 parts by weight of cosolvent isopropanol and 42 parts by weight of solvent liquid paraffin in a container, and stir continuously at room temperature to obtain a uniform liquid, namely Degreasers based on marine fish oils, named Group 3.

Abstract

The invention discloses an oil dispersant based on marine fish oil and a preparation method thereof. According to the oil dispersant, fish oil fatty acid diethanol amide with the marine fish oil being a reaction raw material serves as one of main components. Auxiliary materials comprise penetrating agents, cosolvents, solvents and the like. Under a proper condition, the marine fish oil and diethanolamine react, preparation is performed with an optimized technology, and the non-ionic surfactant fish oil fatty acid diethanol amide is prepared. Raw materials of the oil dispersant come from feed-grade marine fish oil, and the using valve of the feed-grade marine fish oil is improved. In addition, the oil dispersant has a high-efficient oil dispersing effect and can avoid secondary pollution to seawater caused by a traditional oil dispersant. The preparing and producing process of the oil dispersant is simple, reliability is high, and the oil dispersant has good economic benefits.

Description

technical field [0001] The present invention relates to an oil dispersant, more specifically to a marine fish oil-based oil dispersant and a preparation method thereof, the oil dispersant is used for oil spill emulsification when oil spill accidents occur during oil exploitation, transportation and storage , belonging to the field of chemical industry. Background technique [0002] "Oil dispersant", also known as "oil spill dispersant", is composed of a variety of surfactants and strong penetrating solvents. It is mainly used to deal with marine oil spills and clean oil pollution. It is an essential product for the treatment of marine oil pollution. Its mechanism of action is to use the emulsification of surfactant to emulsify the oil film to form O / w emulsion. Solvents reduce the viscosity of oils, making them easier to emulsify. And a small amount of additives can promote the emulsification and dispersion process, improve the emulsification efficiency, and increase the s...
