1-Nitroso-2-Naphthol-3, 6-Disulphonic Acid Disodium Salt What are the precautions when storing
1-Nitroso-2-naphthol-3,6-disulfonic acid disodium salt, this is a chemical agent. When storing, many things need to be paid attention to.
First, choose a suitable container. Because of its specific chemical properties, corrosion-resistant containers, such as glass bottles, should be selected to prevent the chemical from reacting with the container and causing it to deteriorate. Do not use metal containers that are easy to react with, so as not to affect the quality of the drug.
Second, the temperature and humidity of the storage environment are very important. It should be stored in a cool, dry place, where the temperature is too high, or the decomposition of the drug is accelerated; if the humidity is too high, it may cause it to deliquescent. The temperature of the warehouse should be controlled between 15-30 degrees Celsius, and the relative humidity should be maintained at 40% -70%.
Third, light also affects it. This agent may be sensitive to light, so it should be stored away from light. It can be placed in a brown bottle or stored in a place without direct light to prevent changes such as degradation of the agent caused by light.
Fourth, it needs to be stored separately from other chemicals. This agent may react with certain substances, such as strong oxidizing agents, reducing agents, etc., and should be avoided from mixing with it to prevent dangerous chemical reactions and safety accidents.
Fifth, the storage place should be well ventilated. If the ventilation is not smooth, the volatile gas of the drug will accumulate, which may cause health risks, or increase safety hazards such as explosions. Be sure to ensure smooth air circulation in the storage space.
Sixth, do a good job in marking management. In a prominent place in the storage container, clearly mark the name, specification, production date, valid period and other information of the drug to facilitate management and access, and at the same time avoid misuse.
Only by strictly following these precautions can the stability and safety of 1-nitroso-2-naphthol-3,6-disulfonate disodium salt during storage be ensured.
1-Nitroso-2-Naphthol-3, what is the production process of 6-Disulphonic Acid Disodium Salt?
The production process of 1-nitroso-2-naphthol-3,6-disulfonic acid disodium salt is a delicate and complicated process. At the beginning, it is necessary to select high-quality naphthol as raw material. This naphthol must have high purity and few impurities before it can lay a good foundation for the subsequent reaction.
Place naphthol properly in a specific reaction vessel, and slowly add an appropriate amount of nitrifying reagent according to the precise ratio. The amount of this nitrifying reagent needs to be strictly controlled. If it is too much, if it is not enough, it can affect the quality of the product. During the reaction, the control of temperature and time is crucial. The temperature should be maintained at a specific range. If it is too high, the reaction will be too fast and by-products will be easily produced. If it is too low, the reaction will be slow and take too long. The reaction time also needs to be precisely pinched to the right extent to make the conversion of naphthol to 1-nitroso-2-naphthol smooth.
Then, transfer 1-nitroso-2-naphthol into another reaction system and add a sulfonating reagent. The sulfonation process also needs to be carefully controlled. Factors such as the addition speed of reagents and the pH of the reaction environment will affect the effect of sulfonation. After this step, 1-nitroso-2-naphthol-3,6-disulfonic acid can be obtained.
Finally, 1-nitroso-2-naphthol-3,6-disulfonic acid is fully reacted with sodium hydroxide solution to generate 1-nitroso-2-naphthol-3,6-disulfonic acid disodium salt. After the reaction is completed, impurities are removed through a series of separation and purification methods, such as crystallization, filtration, drying, etc., to obtain a pure product. This product has been strictly inspected and all indicators meet the standards before it can be used as a finished product for various industries.
