Two-component organic gel composition and application thereof

Abstract

The invention discloses a two-component organic gel composition. The two-component organic gel composition is prepared by mixing two gelators, namely cyclohexylamine and 2-n-hexyldecanoic acid, with any one of benzene, methylbenzene, o-xylene, m-xylene or p-xylene. The organic gel can be directly cured at room temperature to form stable organic gel, the operation process is simple, the cost is low, and the organic gel can be used for treating leakage and recovery of benzene, methylbenzene, o-xylene, m-xylene or p-xylene. Meanwhile, the organic gel formed by curing the leakage liquid is rectified, the leakage liquid and gel factors in the organic gel are easy to recover, harmlessness of the leakage liquid and recycling of a reaction solvent are achieved, and the method has important practical significance in improving economic and environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of chemistry, and relates to a two-component organic gel composition and its application in the treatment and recovery of leakage of benzene, toluene, o-xylene, m-xylene or p-xylene. Background technique [0002] In recent years, gels, as an important part of supramolecular chemistry, have attracted extensive attention from researchers due to their special properties and simple preparation process. As a thermoreversible soft material, supramolecular gel is generally composed of a small amount of gelling factor and a large amount of solvent. The gel factor self-assembles to form a three-dimensional network structure through weak interactions such as hydrogen bonds, van der Waals forces, π-π interactions, electrostatic interactions, and hydrophobic interactions, and then solvent molecules fill the network voids of the gel to form a jelly-like structure without fluidity. There are many ways to classify supramo...

Problems solved by technology

Among them, the adsorption method has problems such as large amount of use, low adsorption efficiency, and high cost in the recovery and treatment of benzene series; the equipment and operation of the condensation method are relatively simple, but in order to obtain a higher recovery rate, it often requires high pressure and low temperature conditions. The difficulty and cost of recovery are increased; the treatment effect of the thermal destruction method can be as high as 99%, but it needs to be burned with auxiliary fuel, which is costly and easy to cause secondary pollution; the biodegradation method is only for low-concentration benzene The recycling efficiency of waste water is high, and it is easily affected by the external environment
