What are the precautions for 1-anthracenesulfonic acid, 9,10-dihydro-9,10-dioxo-, ammonium salts in the production process?
The production of 1-borosilicate acid and 9,10-dioxy-9,10-dioxide in alum kiln involves many precautions and needs to be handled with caution.
First, the selection of raw materials must be carefully selected. When the quality of borosilicate acid is pure and free of impurities, if it contains impurities, it will affect the quality of the finished product. 9,10-dioxy-9,10-dioxide also needs to strictly control the purity. Impurities are mixed in, or the kiln changes abnormally, and the finished product defects are frequent.
Second, the control of the temperature is crucial. Alum kiln firing, the size and duration of the fire are fixed. If the fire is too fierce, the material or overreaction will cause the composition to be unbalanced; if the fire is insufficient, the reaction will be insufficient and it will be difficult to achieve the expected quality. Experienced craftsmen are required to always pay attention to changes in the heat and adjust in a timely manner according to the situation in the kiln.
Third, the environment in the kiln should not be ignored. The ventilation and humidity in the kiln will affect the firing. If the ventilation is not smooth, the exhaust gas is difficult to discharge, or there is an adverse reaction with the material; if the humidity is too high, it is easy to cause the material to get damp, which will affect the firing process and the quality of the finished product. Therefore, it is necessary to keep the kiln well ventilated and the humidity is suitable.
Fourth, the operation process must be standardized and rigorous. From the Materials should be placed evenly and orderly to ensure consistent heating; during the firing process, check regularly and do not slack off. When leaving the kiln, you also need to pay attention to the cooling rhythm to avoid sudden cooling and sudden heat to cause the finished product to break.
Alum kiln firing borosilicate and related compounds, all the precautions are interlinked, which is related to success or failure. Craftsmen should strictly abide by the norms and refine their skills in order to produce high-quality products.

What are the environmental effects of 1-anthracenesulfonic acid, 9,10-dihydro-9,10-dioxo-, ammonium salts?
Substances such as 9,10-dibromostearic acid, 9,10-dihydro-9,10-dioxo-and stearic acid have a complex impact on the environment.
Let's talk about 9,10-dibromostearic acid first, which contains bromine. Brominated flame retardants are difficult to degrade in the environment and are easy to accumulate. After entering the environment, they may be adsorbed on soil particles, affecting soil microbial activity and soil fertility, and interfering with the normal function of soil ecosystems. If rain initializes into water bodies, it will endanger aquatic organisms. Because it is biotoxic, it may cause aquatic organisms to grow, reproduce and even die. And it may be transmitted through the food chain and enriched in high nutrient-level organisms, threatening human health.
9,10-Dihydro-9,10-dioxo-If these substances enter the environment, they may be toxic to specific organisms due to their chemical structure characteristics. In natural water bodies, they will change the chemical properties of the water body, affect the pH and dissolved oxygen content of the water body, and destroy the aquatic ecological balance. In the soil, or react with minerals and organic matter in the soil, changing the chemical composition and structure of the soil.
Stearic acid is less toxic than the first two, but it also has an impact on a large amount of emissions. In water bodies, it will reduce the surface tension of the water body, affect the gas exchange between the water surface and the atmosphere, and indirectly affect the respiration of aquatic organisms. When it decomposes in the soil, it may consume a lot of oxygen, causing local hypoxia in the soil, affecting the survival of aerobic microorganisms, and then changing the soil ecological environment.
In short, these substances need to be properly controlled during production, use and disposal to prevent serious and lasting adverse effects on the environment.
