Compound for treating cyclohexane organic waste liquid and preparation method thereof

Abstract

The invention discloses a compound for curing cyclohexane-containing organic waste liquid as well as a preparation method and application of the compound. The method comprises the following steps: dissolving raw materials cholesterol formyl chloride and ethidene diamine in a chloroform system for reaction to prepare N-cholesterol formyl ethidene diamine, and then dissolving the N-cholesterol formyl ethidene diamine, oleic acid and N, N '-dicyclohexylcarbodiimide in the chloroform system for reaction to prepare N-(N-cholesterol formyl)-ethylene-9-octadecenoic acid amide. Tests show that the prepared compound for curing the cyclohexane-containing organic waste liquid can effectively cure various kinds of cyclohexane-containing organic waste liquid, and has wide application prospects in the aspects of storage and transportation of the cyclohexane-containing organic waste liquid.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis and supramolecular chemistry, and in particular relates to a compound used for curing cyclohexane organic waste liquid at normal temperature, as well as a specific preparation method and application thereof. Background technique [0002] Cyclohexane, an organic compound with the chemical formula C 6 H 12 , is a colorless liquid with a pungent odor, the boiling point is 80.72 ℃, insoluble in water, soluble in various organic solvents such as ethanol, cyclohexane, benzene, acetone, etc., very volatile and flammable. The properties of cyclohexane make it widely used. It is generally used as a solvent, a standard material for chromatographic analysis and for organic synthesis. It can be used in resins, coatings, fats, paraffin oils, and can also be used to prepare cyclohexanol and cyclohexane. ketones and other organic substances. The extensive use of cyclohexane inevitably results in a ...

AI Technical Summary

Problems solved by technology

[0005] However, there are still the following problems in the storage of cyclohexane organic waste liquid: (1) The storage conditions of cyclohexane are harsh, and it should be placed in a cool and ventilated warehouse, away from fire, heat sources, oxidants, etc., and the storage temperature should not exceed 30 °C , keep the airtightness of the container, have high requirements on the storage environment, and increase the construction cost of the warehouse

(2) Due to its nature, it must be treated as hazardous waste, which increases the burden on operators

The following problems exist in the transportation process: (1) It is strictly forbidden to mix with oxidants, which greatly reduces the efficiency of waste liquid treatment and increases the cost of waste liquid treatment; (2) Slight shocks during transportation can also cause explosions, which are harmful to transportation vehicles and Road conditions and other requirements are harsh, and the road needs to be blocked during the transportation period to avoid safety threats to unrelated personnel; (3) Operators must be professionally trained and qualified to participate in transportation, and self-priming filter gas masks must be worn during the operation , wear safety goggles, wear anti-static overalls, wear rubber oil-resistant gloves, etc., which raises the cost of waste liquid treatment

However, in the traditional gel preparation process, operations such as stirring, heating and cooling, and ultrasonic induction are required. These operations are complicated and time-consuming. More importantly, during the heating process, accidents such as explosions and operator poisoning may occur. A series of safety issues, so there are few reports on the use of supramolecular gels to solidify cyclohexane organic waste liquid
