Abstract

The invention discloses a preparation method of a magnetic hydroxyl stearate oil gelling agent. The method comprises the following steps: hardened oil and sodium hydroxide are heated in water, such that a saponification reaction is carried out; impurities are removed after the reaction, such that sodium stearate is prepared; the sodium stearate and sodium hydroxide are added in water; a reaction is carried out under stirring and heating; a metal salt is slowly added under stirring; magnetic iron tetraoxide nano-powder is instantly added; a reaction is carried out for 0.5-2h under stirring under a temperature of 80-95 DEG C; an obtained product is washed several times; and filtering, drying and sieving are carried out, such that the magnetic hydroxyl stearate oil gelling agent is obtained. The magnetic hydroxyl stearate oil gelling agent preparation method is simple, and has the advantages of low cost, convenient application, and good oil gelling effect.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, in particular to a preparation method of a magnetic hydroxystearate oil gelling agent. Background technique [0002] The vigorous development of the marine transportation industry and the continuous development of offshore oil resources have brought huge economic benefits to human beings and at the same time produced serious oil spill pollution accidents, posing a great threat to the marine environment. At present, the prevention and control of oil spill pollution at sea has become a major problem facing mankind. A large-scale oil spill accident will cause a large amount of oil to enter the marine environment instantly, and spread on the sea surface to form a thick oil layer, resulting in a large area of ​​ocean hypoxia and endangering the survival of fish and other aquatic organisms. In addition, hydrocarbons in petroleum are very easy to enter and stay in water for a long time, ...
