Embodiment 1～3

[0015] According to the ratio of 75-80wt% sulfuric acid, 0.1-2wt% hexamethyltetramine, 2-3wt% sodium dodecylbenzenesulfonate, 0.9-1wt% citric acid and the balance of deionized water, mix the raw materials evenly , to obtain fog-suppressing sulfuric acid.

[0016] The detailed formula is as shown in Table 1:

[0017] Table 1:

[0018]

[0019] Explanation: in Table 1, the insufficient part of the total mass percentage of the components in the examples is deionized water.

[0020] Taking 80% sulfuric acid as a control example, a comparative test was carried out with the fog-suppressing sulfuric acid obtained in Examples 1-3.

Abstract

The invention belongs to the technical field of chemical preparations, and relates to a fog-suppressing sulfuric acid. Citric acid and the balance of deionized water. This fog-suppressing sulfuric acid can not only achieve a good fog-suppressing effect, reduce volatile pollution, save volatile loss, but also slow down the occurrence of over-corrosion, which is more economical and environmentally friendly, and can be popularized and used in some high-tech fields.

Description

technical field [0001] The invention relates to the technical field of chemical preparations, in particular to an economical and environment-friendly fog-suppressing sulfuric acid. Background technique [0002] Sulfuric acid (chemical formula: H 2 SO 4 ) is the most important oxyacid of sulfur. Anhydrous sulfuric acid is a colorless oily liquid that crystallizes at 10.36°C, and its aqueous solutions of various concentrations are commonly used. Sulfuric acid is the most active binary inorganic strong acid, which is highly corrosive and oxidizing, and can react with many metals. High-concentration sulfuric acid has strong water absorption and can be used as a dehydrating agent to carbonize carbohydrate-containing substances such as wood, paper, cotton and linen fabrics, and biological flesh. [0003] High-concentration sulfuric acid will release a lot of heat after contacting with water, causing boiling, which will form acid mist of sulfuric acid. Therefore, when sulfuric...
