Embodiment 1

[0020] Embodiment 1 toluene diisocyanate and octylamine dosage ratio optimization

[0021] For the configuration of the small molecule gel decontaminant, take 20g of isopropanol, 85g of the total mass of toluene diisocyanate and octylamine, and set the gradient of the dosage ratio of toluene diisocyanate and octylamine to 1:10, 3:10, 5:10, 7:10, 9:10, 10:9, 10:7; Prepare 500g of toluene to be decontaminated, and put it in a container with a surface area of ​​0.2 square meters, and set up 7 containers in total.

[0022] Mix octylamine and isopropanol evenly and spread evenly on the surface of the container, then sprinkle toluene diisocyanate evenly on the surface of the container, start timing, when the mixture in the container appears as figure 1 When the gel state is shown, stop timing and calculate the time (s) for gel formation.

[0023] Measurement results such as figure 2 As shown, when the mass ratio of toluene diisocyanate and octylamine is 7:10, the gel formation ti...

Embodiment 2

[0024] Embodiment 2 isopropanol and toluene diisocyanate and octylamine total mass ratio optimization

[0025] Isopropanol is used as a dispersant, the amount of addition will affect the viscosity, mechanical properties and encapsulation rate of the final gel, and will eventually affect the volatilization of toluene in the gel.

[0026] The configuration of the small molecule gel decontaminant, the total amount is 105g, the dosage ratio of toluene diisocyanate and octylamine is 7:10, the mass ratio of isopropanol to the total mass of toluene diisocyanate and octylamine, and the gradient is set to 1: 1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8; prepare 900g of toluene to be decontaminated, put it in a container with a surface area of ​​0.2 square meters, and set up 8 in total container.

[0027] Mix octylamine and isopropanol evenly and spread it evenly on the surface of the container, and then sprinkle toluene diisocyanate evenly on the surface of the container, when the mixture in ...

Embodiment 3

[0031] The optimum amount optimization of embodiment 3 gel decontamination agent

[0032] For the configuration of small molecule gel decontaminants, take 20g of isopropanol, 35g of toluene diisocyanate, 50g of octylamine, and dissolve octylamine in isopropanol; 8% of the mass), 1050g (10%), 750g (14%), 538.3g (18%), 477.3g (22%), 403.8g (26%), 350g (30%) placed on a surface area of ​​0.2 square meters In the container, a total of 7 containers are set.

[0033] Mix octylamine and isopropanol evenly and spread it evenly on the surface of the container, and then sprinkle toluene diisocyanate evenly on the surface of the container, when the mixture in the container appears as figure 1 When the gel state is shown, the gel is formed.

[0034] After the gel was formed, the detection method as in Example 2 was used to detect the volatilization of toluene, and the detection results were as follows: Figure 4 As shown, the amount of gel decontaminant used is 18% of the mass of tolue...

Abstract

The invention discloses a small molecular gel decontaminating agent. The gel decontaminating agent is prepared from the following components in parts by weight: 30-40 parts of toluene diisocynate, 45-55 parts of octylamine and 15-25 parts of isopropanol. According to the product, isopropanol is used as a lubricant, toluene diisocynate and octylamine are used as gel auxiliaries, isopropanol can reduce the viscosity of other components and is convenient to disperse, toluene diisocynate and octylamine are subjected to a chemical reaction, a small molecular substance generated through the reactionis a gel, and a gel skeleton can be generated through the hydrogen bond action to wrap toluene. The product disclosed by the invention is high in reaction speed, and a curing effect can be achieved within 2 minutes; the dosage of the decontaminating agent is small, the decontaminating agent can be cured when the content of the decontaminating agent is about 8%, and various parameters of a decontaminating product are optimal when the content is 18%; and the decontamination product is convenient for subsequent treatment and can be quickly recycled.

Description

technical field [0001] The invention belongs to the technical field of post-disposal treatment of dangerous chemical goods, and in particular relates to a small molecule gel decontaminant. Background technique [0002] With the rapid development of my country's modern industry, toluene is an important chemical raw material, and leakage accidents occur frequently due to various reasons. Toluene has the characteristics of flowing and volatilizing rapidly, burning and exploding when exposed to heat or open flame, and having a great poisonous effect on the surrounding environment and human body. The characteristic is that once such hazardous chemicals leak, if the situation cannot be controlled in a short time to curb the development, it will cause pollution of the surrounding soil and water bodies at the slightest, and cause casualties or even cause serious consequences such as fire and explosion. In dealing with such leakage accidents of hazardous chemicals, the emergency rescu...
