To prepare 4-amino-1-naphthalenesulfonic acid bismuth ointment, the method is as follows:
Prepare various drugs first, and an appropriate amount of bismuth compound is required, 4-amino-1-naphthalenesulfonic acid is also taken in an appropriate amount, and an appropriate amount of ointment base, such as Vaseline.
The bismuth compound is finely ground to make its particle size suitable for subsequent fusion with other substances. 4-amino-1-naphthalenesulfonic acid is also appropriately treated, or finely ground, or prepared according to its characteristics.
Take a clean vessel and slowly heat the ointment substrate over a low heat to make it molten. This process needs to be carefully observed. Do not overheat to avoid deterioration of the substrate. When the substrate is melted, add the ground bismuth compound slowly, and stir quickly with a clean appliance to make the bismuth compound evenly dispersed in the substrate.
Then, add the treated 4-amino-1-naphthalene sulfonic acid slowly, and continue to stir, so that the three are fully mixed. When stirring, the action should be steady and uniform, and the ingredients must be fused seamlessly.
When mixed evenly, remove from the fire source, then stir non-stop, so that the mixture is gradually cooled. When it is cooled to an appropriate temperature and in the state of an ointment, 4-amino-1-naphthalenesulfonate bismuth ointment is prepared.
During the entire preparation process, attention should be paid to the clean environment to avoid impurities from mixing, and each step should be handled with caution. According to the above method, qualified 4-amino-1-naphthalenesulfonate bismuth ointment can be obtained.

For cobalt oxime 4-hydroxy-1-naphthoate, many precautions need to be paid attention to during storage and transportation.
Its chemical properties are relatively active, and when storing, it should be placed in a cool, dry and well-ventilated place. It must not be stored and transported with oxidants, acids, etc., because it is easy to chemically react with such substances and cause danger. The temperature of the warehouse should be constant, and the humidity should also be properly controlled to prevent it from deteriorating due to changes in temperature and humidity.
During transportation, the packaging must be strong and tight to prevent leakage. The means of transportation used must be clean and pollution-free to avoid impurities from mixing in and affecting its quality. During the loading and unloading process, the operation should be gentle, and the loading and unloading should not be brutal to prevent the packaging from being damaged. If the transportation environment is high temperature, appropriate cooling measures are required, because it is prone to change in nature due to heat.
In addition, personnel engaged in storage and transportation, when professionally trained, are familiar with the characteristics of 4-hydroxy-1-naphthoate cobalt oxime and emergency treatment methods. In the event of an accident such as leakage, they can respond quickly and correctly. All kinds of documents and procedures required by the relevant departments during transportation should also be complete and transported in accordance with regulations to ensure the safety of the whole process. In this way, the stability and safety of 4-hydroxy-1-naphthoate cobalt oxime during storage and transportation must be ensured.

4-Hydroxy-1-naphthalenesulfonate cadmium salt, this substance has an impact on the environment and human health.
At the environmental end, it may be at risk to water storage ecology. If it flows into rivers, lakes and seas, it can cause harm to aquatic organisms. Aquatic organisms have different sensitivities to it, or interfere with their normal physiological functions, such as affecting the respiration and reproduction of fish, resulting in population loss; for plankton, it may change their growth rate and metabolism, thereby disrupting the balance of the aquatic ecosystem and the stability of the food chain. And accumulation in the soil, or affect the activity of soil microorganisms, hinder soil nutrient cycling and plant root uptake of nutrients, resulting in vegetation growth hindered.
At the healthy end of people, there are different contact routes. If inhaled through the respiratory tract, the particles of the substance enter the lungs, or irritate the mucosa of the respiratory tract, causing cough, asthma and other discomfort. Long-term exposure, or damage to lung tissue, increases the risk of respiratory diseases. If exposed through skin, or cause skin allergies, itching, redness and swelling and other symptoms, it may be irritating and destroy the skin barrier. If ingested inadvertently, it is also harmful to the digestive system, or irritate the intestinal and gastric mucosa, causing abdominal pain, diarrhea, and in severe cases affecting organ function. In addition, it may have potential carcinogenicity and genetic toxicity. Although relevant research needs to be in-depth, this latent risk cannot be ignored. Therefore, cadmium 4-hydroxy-1-naphthalenesulfonate should be treated with caution, and supervision and protection should be strengthened to avoid its serious harm to the environment and human health.
