In the field of organic synthesis, it is like a powerful assistant, often used as a catalyst or reaction intermediate. It helps various organic reactions proceed smoothly, promotes the birth of new substances, and contributes to the development of organic chemistry.
1-Octanesulphonic Acid, Sodium Salt What to pay attention to when storing
1 - Octane sulfonic acid is not good enough, and there are many people who should pay attention to it. This physical property is not good, but there are many problems, which cannot be ignored.
First, moisture-proof is essential. 1 - Octane sulfonic acid is easy to absorb moisture, moisture absorption or its properties, such as the decrease in temperature, the change of flow, and even the influence of its chemical activity. Therefore, if it is dry, if there are some parts, it can be placed in the dry device to keep the dry environment.
Second, avoid it. Under high temperature, 1-Octane sulfonic acid is not good or biodegradable, so that its amount is affected. The best storage is often, in general, 15 ℃ - 35 ℃ is appropriate. Do not be near fire or heat sources, such as cooking stoves, heating cans, etc., to prevent damage due to damage.
Third, anti-oxidation cannot be ignored. Its oxidation resistance is still good, but it is exposed to air during the period, and there is a risk of oxidation. Therefore, the container should be well sealed and sealed immediately, and it should be connected with less air. If it is stored in a glass bottle, it will be turned around. If it is used in a plastic container, it will also be sealed and leaked.
Fourth, it is common to store it separately. It is not necessary to oxidize or oxidize the original material, because it may cause intensification and reaction, resulting in danger. And different grades and batches should also be placed separately, which is convenient for management and access, and is also conducive to traceability.
Therefore, 1-octane sulfonic acid should be stored in the warehouse, and attention should be paid to moisture-proof, moisture-avoidance, oxidation-proof and sub-storage. In this way, the amount of 1-octane sulfonic acid can be guaranteed.
1-Octanesulphonic Acid, Sodium Salt What is the preparation method
1-Octanesulphonic acid, sodium salt, namely 1-Octanesulphonic Acid, Sodium Salt, the preparation method is as follows:
First, octene and sodium bisulfite are used as raw materials, and the two are added in a specific reaction vessel under suitable temperature and pressure conditions. The principle of this reaction is that olefins have unsaturated double bonds and can undergo electrophilic addition with sodium bisulfite. The reaction formula is roughly as follows: $C_ {8} H_ {16} + NaHSO_ {3}\ longrightarrow C_ {8} H_ {17} SO_ {3} Na $.
During the reaction process, it is necessary to closely monitor the temperature, generally maintained at 40-60 ° C. Due to high temperature, side reactions may be triggered, resulting in impure products; if the temperature is too low, the reaction rate will be slow and time-consuming. In terms of pressure, it is often controlled between normal pressure and slightly higher than normal pressure. This pressure condition is not only conducive to the reaction, but also convenient for operation and equipment maintenance.
After the reaction is fully completed, in addition to the target product 1-octane sulfonate sodium salt, the reaction mixture still contains impurities such as unreacted raw materials, by-products and solvents. At this time, the reaction mixture is initially separated, and insoluble impurities can be removed by filtration.
Then, distillation is used to remove most of the volatile solvents. The remaining concentrate is then crystallized, and an appropriate amount of organic solvent, such as ethanol or acetone, is slowly added to the concentrate to reduce the solubility of the product and promote its crystallization.
After the crystallization is complete, the crystals are collected by suction filtration and washed with an appropriate amount of cold solvent to further remove impurities attached to the crystal surface. Finally, the resulting crystals are placed in an oven and dried at a suitable temperature to obtain a pure 1-octane sulfonate sodium salt product.
The whole preparation process requires strict control of the conditions of each step to ensure the purity and yield of the product.
1-Octanesulphonic Acid, Sodium Salt Quality Standards
1-Octane sulfonic acid, sodium salt, often involves quality regulations, related to the purity and purity of chemical use. Common quality standards are as follows:
First, it is related to purity. The purity of this product is extremely important. High-purity 1-octane sulfonic acid, sodium salt, less impurities, in various chemical experiments and industrial processes, can ensure the accuracy of the reaction and the accuracy of the results. Generally speaking, the purity of excellent products is often above 99%, and the purity of first-grade products needs to be about 98%. If the purity is not reached, impurities or disturbances in the reaction process will cause the product to be impure, especially in fields such as medicine and electronics that require purity.
Second, look at its moisture content. The amount of moisture has a great impact. Excessive water, or change the physical properties of substances, in some reactions that require an anhydrous environment, or cause reactions to be difficult, or produce side reactions. Therefore, in common standards, the moisture content is limited to less than 1% to ensure the stability of its chemical properties.
Third, the content of metal ions is also key. For example, metal ions such as sodium, potassium, and iron, if the content exceeds the standard, or affects their chemical activity, in a specific catalytic reaction, or poisons the catalyst, reducing the reaction efficiency. Usually, the content of heavy metal ions is controlled at the ppm level, that is, less than one part per million.
Fourth, the particle size distribution is also considered. If used in the preparation of specific preparations or materials, the appropriate particle size can increase its dispersion and solubility. The average particle size may be within a certain range, such as several microns to tens of microns, to better meet the needs of different applications.
