Abstract

The invention relates to the technical field of fuel thickeners, solves the problem that commercial application is difficult due to high production cost and poor adaptability of the fuel thickener, and discloses a fuel thickener containing glyceryl selective supermolecules as well as a preparation method and application of the fuel thickener. The glyceryl selective supermolecules are represented by a general formula I, wherein R is C12-18 saturated alkyl. The preparation method of the fuel thickener comprises the following steps: adding glyceraldehydes into water, heating and raising the temperature, stirring to form a glyceraldehyde solution; adding an acidic material to regulate the pH value, adding dodecyl 1-naphthylhydrazine, continuously stirring and reacting, adding an alkaline matter to regulate the pH value, filtering, and sequentially washing with water and ethanol, thereby obtaining the fuel thickener containing glyceryl selective supermolecules. The fuel thickener disclosedby the invention is simple and feasible, the raw materials are cheap, no large equipment is needed, and the fuel thickener is easy to master and capable of realizing industrial production.

Description

technical field [0001] The invention relates to the technical field of oil coagulants, in particular to an oil coagulant containing glyceryl selective supramolecules, a preparation method and application thereof. Background technique [0002] With the rapid development of offshore oil development and marine transportation, marine oil pollution has been paid more and more attention by countries all over the world. Oil spills at sea mainly come from ship operations and ship accidents, especially accidental accidents such as oil tanker accidents, oil platforms, oil storage and oil transportation facilities, etc. , Looking at China's industrial layout, petrochemical products are concentrated in the eastern coastal areas, and they are distributed along the coast, along the river, and along the river. Once an oil spill occurs, it will seriously pollute the water environment. Oil coagulants are commonly used chemical agents in the emergency treatment of river and ocean oil spill p...
