What are the physical properties of 1,5-Pentanedisulfonic Acid, 1,5-Dihydroxy-, Sodium Salt (1:2)?
1,5-Glutaresulfonic acid, 1,5-dihydroxy-, sodium salt (1:2), its physical properties are as follows. Under normal conditions, this substance may be a white crystalline powder, which is pure and delicate in appearance. It has good solubility in water, because it has sulfonic acid groups and hydroxyl groups in the molecule, both of which are hydrophilic groups, which can strongly interact with water molecules to form a stable hydrated structure, so it is easily soluble in water.
Melting point is one of the key physical constants, but the exact value may vary according to experimental conditions and is roughly in a specific temperature range. This melting point characteristic is due to intermolecular forces, including hydrogen bonds, van der Waals forces, etc. At a specific temperature, the molecule is energized enough to overcome these forces, and the lattice structure disintegrates and melts.
Its density is also an inherent property, reflecting the degree of tight packing of molecules. The arrangement of atoms and the spatial distribution of groups in the molecular structure determine its density value. This value is relatively stable under specific conditions and is an important reference for identification and application.
In addition, this substance is hygroscopic or strong, and water vapor in the air is easy to interact with its hydrophilic groups, causing it to absorb water. When storing, pay attention to the ambient humidity to prevent changes in properties due to moisture absorption and affect its quality and application efficiency.
What is the preparation method of 1,5-Pentanedisulfonic Acid, 1,5-Dihydroxy-, Sodium Salt (1:2)?
To prepare 1% 2C5-pentanediol, 1% 2C5-dihydroxy-, sodium salt (1:2), the method is as follows:
First take an appropriate amount of 1,5-pentanediol and place it in a clean reactor. The kettle must first exhaust the air with nitrogen to create an inert atmosphere to prevent side reactions. Slowly add an appropriate amount of fuming sulfuric acid. This process needs to strictly control the temperature and maintain it in the low temperature range, about 0 ° C to 5 ° C is appropriate, and stir must be uniform to make the reaction sufficient. The amount of fuming sulfuric acid should be precisely controlled according to stoichiometry to ensure that 1,5-pentanediol is fully sulfonated.
After the sulfonation reaction is completed, pour the reaction mixture into ice water and stir carefully to dissolve the product. Then, slowly add the sodium hydroxide solution dropwise, adjust the pH of the solution to the alkaline range, about pH = 8-9, to convert the sulfonic acid into sodium salt. The rate of dropwise addition should be slow to prevent local overheating or overreaction.
Once the pH is properly adjusted, remove excess water by vacuum distillation to obtain a thick solution. Then cool the solution and let it stand to crystallize. When the crystallization is complete, separate the crystals by suction filtration and wash with an appropriate amount of cold ethanol to remove impurities. Finally, the resulting crystals are placed in a vacuum drying oven and dried at an appropriate temperature to obtain pure 1% 2C5-glutardisulfonic acid, 1% 2C5-dihydroxy-, sodium salt (1:2). Throughout the operation, strict procedures should be followed to pay attention to safety, prevent strong acids and alkalis from harming people, and properly dispose of waste to abide by environmental protection principles.
1,5-Pentanedisulfonic Acid, 1,5-Dihydroxy-, Sodium Salt (1:2) What are the precautions during storage and use?
For disodium salt of 1,5-pentanediol-1,5-disulfonate, many matters need to be paid attention to during storage and use.
When this medicine is stored, the first environment is dry. Moisture can easily cause deliquescence and affect quality, so it should be placed in a dry place, away from dark and moisture-free places. Temperature is also critical, and it should be stored in a cool environment. Excessive temperature or changes in its chemical properties will accelerate deterioration. Do not expose it to high temperature heat sources.
When using, safety protection must be comprehensive. Because it is a chemical substance, or there is a risk of irritation to the skin and eyes. Therefore, when operating, use protective equipment, such as gloves and goggles, in front of you to prevent inadvertent contact. If it touches the skin, rinse with plenty of water immediately; if it enters the eyes, rinse quickly and seek medical attention.
In addition, the dosage also needs to be precisely controlled. According to the specific use and reaction requirements, use strictly according to the amount. Improper dosage, or poor reaction effect, or cause other side reactions. And the use process needs to follow specific operating procedures, do not act recklessly. Mixing, dissolving and other operations are carried out according to the specifications to ensure the smooth progress of experiments or production, and to ensure the safety of personnel and the environment.
