Embodiment 1

[0035] A method for synthesizing a high-molecular degreasing agent for oil spills is prepared by stirring each comonomer in a solvent under the condition of the presence of an initiator, carrying out a copolymerization reaction and corresponding post-treatment.

[0036] 1. Raw materials

[0037] Monomer: Isooctyl Acrylate (2EHA)

[0038] Styrene (St)

[0039] Lauric acid (DA)

[0040] Butylamine (BA)

[0041] Molar ratio 2EHA:St:LA:BA=1:1:1.5:1

[0042] Initiator: benzoyl peroxide (BPO), the amount used in the reaction system is 0.5% of the monomer mass

[0043] Solvent: Methyl Oleate (3:1 solvent to all other ingredients by weight)

[0044] 2. Process

[0045] In a stainless steel reaction kettle equipped with a stirrer, a constant pressure drop tank, a thermometer and a condenser, first put DA and 70% solvent methyl oleate into the reaction kettle, stir and heat to melt the lauric acid, and continue heating When the temperature reaches 60°C, add dropwise the methyl olea...

Embodiment 1

[0047] In Example 1, 20% of the initiator solid is first thrown into the reactor, heated together with DA and 70% of the solvent, and the remaining initiator is added dropwise to the solution of the monomer into methyl oleate in the reactor, and other Constantly, obtain the polymer oil dispersant product XYJ-2 for oil spill of the present invention

Embodiment 3

[0049] 1. Raw materials:

[0050] Monomer: lauryl acrylate (LA)

[0051] N-vinylpyrrolidone (NVP)

[0052] Lauric acid (DA)

[0053] Styrene (St)

[0054] Butylamine (BA)

[0055] Molar ratio 1:1.5:2:1:1

[0056] Initiator: Azobisisobutyronitrile (AIBN), the amount used in the reaction system is 0.5% of the monomer mass

[0057] Solvent: butanone (3:1 weight ratio of solvent to all other raw materials).

[0058] 2. Process

[0059] In a stainless steel reaction kettle equipped with a stirrer, a constant pressure drop tank, a thermometer and a condenser, put LA and 70% butanone into the reaction kettle first, stir and heat the solid to melt, and continue heating to a temperature of 60°C. At the same time, dropwise add the methyl ethyl ketone solution mixed with LA, NVP, St and AIBN, and control the dropwise addition time at 1~1.5h. After the dropwise addition, raise the temperature to 70°C and keep it warm for 2h to make the reaction complete. After the reaction, use tr...

Abstract

The invention relates to an efficient and low-toxicity oil dispersant for spilled oil and a synthesizing method of the efficient and low-toxicity oil dispersant. The efficient and low-toxicity oil dispersant is characterized in that a macromolecule oil dispersant structure is used as the 'comb-shaped' structure, the macromolecule oil dispersant structure is obtained by unsaturated monomers through grafting and copolymerization, a molecular skeleton comprises a main chain and many branch chains, the main chain contains many active groups such as -CH3, -C(CH3)3, -COOR and -C6H5, the main chain can 'anchor and wrap' the surface of the spilled oil by the aid of the active groups to micro-emulsify the spilled oil, hydrophilic groups with good water compatibility are introduced into side chains, the oil dispersant structurally comprises two parts, one part is anchoring groups, the spilled oil can be coagulated into blocks due to the fact that the long chain branches of the comb-shaped-structure oil dispersant wrap a large amount of spilled oil, and environment protection departments can easily recycle the spilled oil.

Description

technical field [0001] The invention relates to a high-efficiency and low-toxic oil spill dispersant and a synthesis method thereof. Background technique [0002] With the rapid development of marine shipping industry and offshore oil extraction industry, oil spill pollution from ships and oil spills has become the pollution source with the highest frequency, the widest distribution area and the most harmful degree among various types of marine pollution. It not only poses a huge threat to the survival of marine organisms and causes a large number of marine organisms to mutate or even die, but also causes serious damage to the safety of the marine ecological environment, and some even irreparable damage. Dispersants play a very important role in the clean-up process after an oil spill at sea. Oil dispersant to deal with oil spill accidents is to condense floating oil in a large area into small suspended oil droplets to accelerate the dissolution, so as to increase the conta...
