Embodiment 1

[0025] A. Weigh 10g of acetylene copper ore slurry, put it in a container, add 10g of distilled water, and stir evenly. Add 2ml of hydrogen peroxide and stir evenly, quickly add 2ml of prepared dilute sulfuric acid (S2) into the container, stir in an oil bath, and react at room temperature for 5h. Reactive gases were collected with gas bags. After the reaction, the pH value was adjusted to 11-12 with NaOH, and then the residue after the reaction was centrifuged, washed three times, and dried at 60° C. to obtain the residue sample M2.

[0026] B. Weigh 10g of acetylene copper ore slurry, put it in a container, add 10g of distilled water, and stir evenly. Add 2ml of hydrogen peroxide and stir evenly, quickly add 4ml of prepared dilute sulfuric acid (S4) into the container, stir in an oil bath, and react at room temperature for 5h. Reactive gases were collected with gas bags. After the reaction, the pH value was adjusted to 11-12 with NaOH, and then the residue after the react...

Embodiment 2

[0035] A. Weigh 10g of acetylene copper ore slurry, put it in a container, add 10g of distilled water, and stir evenly. Add 2ml of hydrogen peroxide and stir evenly, add 5ml of prepared dilute nitric acid (S5) into the container, stir in an oil bath, and react at room temperature for 5h. Reactive gases were collected with gas bags. After the reaction, the pH value was adjusted to 11-12 with NaOH / KOH, the residue after the reaction was centrifuged, washed three times, and dried at 60° C. to obtain the residue sample M5.

[0036]B. Weigh 10g of acetylene copper ore slurry, put it in a container, add 10g of distilled water, and stir evenly. Add 2ml of hydrogen peroxide and stir evenly, add 10ml of prepared dilute nitric acid (S10) into the container, stir in an oil bath, and react at room temperature for 5h. Reactive gases were collected with gas bags. After the reaction, the pH value was adjusted to 11-12 with NaOH / KOH, the residue after the reaction was centrifuged, washed t...

Abstract

The invention discloses a method for treating industrial catalytic waste copper acetylide. The method is characterized in that the method comprises the following steps that a, industrial catalytic waste copper acetylide slurry is taken and put into a container, distilled water with a mass of 1-1.5 times of the copper acetylide slurry is added, and stirred evenly; b, hydrogen peroxide with a mass of 0.15-0.5 times of the copper acetylide slurry is added into the container and stirred evenly; c, a diluted acid solution with a concentration of 15%-30% is added into the container, stirred, reactedat room temperature for 5h, and reaction gas is collected with an air bag; d, after the reaction, an alkali solution is added to adjust a pH value of a reaction solution to 11-12, then the reaction residue is centrifugated, washed for three times, and the obtained centrifugal solution can continue to be recycled; and e, residue samples are obtained by drying at 60 DEG C, and whether the deflagration exists or not in a muffle furnace at 150 DEG C is observed.

Description

technical field [0001] The invention relates to the field of treatment, utilization and recovery of industrial catalytic waste acetylene copper, in particular to an explosion-proof safety technology for industrial catalytic waste acetylene copper. Background technique [0002] With the rapid development of the world economy and the rapid advancement of industrialization, the demand for polymer synthesis chemical production is becoming more and more important in today's society. In polymer synthesis chemical production, acetylene is widely used as the basic raw material for organic synthesis, mainly in synthetic rubber. , synthetic organic solvents, synthetic resins, and synthetic fibers as the main important raw materials. Dozens of important macromolecular monomers can be synthesized from acetylene through cyclopolymerization, chain polymerization or addition reactions, and finally many synthetic polymer products can be made. However, in a considerable part of the process,...
