Sodium and sodium p-toluenesulfonate have a wide range of uses. In the industrial field, sodium p-toluenesulfonate can be used as an emulsifier and dispersant. Taking the printing and dyeing industry as an example, it can help the dye to be evenly dispersed on the fabric, making the dyeing more uniform and the color brighter.
In the manufacture of detergents, sodium p-toluenesulfonate also has important functions. It can enhance the decontamination ability of detergents, making it easier for oil stains and other stains to detach from the surface of objects, resulting in better washing effect.
Furthermore, in the field of organic synthesis, this compound is often used as an intermediate in organic synthesis. Through specific chemical reactions, many organic compounds with special properties and uses can be derived from them, which are then used in many fine chemical industries such as medicine and pesticides.
In the leather industry, sodium p-toluenesulfonate helps in the tanning process of leather, which can improve the quality and durability of leather. In short, sodium and sodium p-toluenesulfonate play a key role in many industries and play an indispensable role in industrial production and daily life.
What are the physical properties of Sodium P-Toluen Sulfonate?
The physical properties of sodium and sodium p-toluenesulfonate are as follows:
Sodium p-toluenesulfonate is a white crystalline powder with pure and positive color. Its taste is slightly salty and it is easily soluble in water. This is due to the strong hydrophilicity of the sulfonic acid group, which interacts with water molecules, so that it can be well dispersed in the aqueous phase. Its melting point is quite high, about 300 ° C. This characteristic is due to the strong interaction force between molecules. To make it melt, more energy is required to overcome this force. The density of sodium p-toluenesulfonate is about 1.24g/cm ³, which is similar to the density of many common organic salts. This density value reflects the close arrangement of its molecules. In organic solvents, sodium p-toluenesulfonate has limited solubility, but it has a certain solubility in polar organic solvents such as dimethyl sulfoxide, which is due to the principle of polar similarity and miscibility.
The sodium element, at room temperature and pressure, is a silver-white metal with a soft texture and can be easily cut with a knife, just like cutting fat. Its density is smaller than that of water, only about 0.97g/cm ³, so it can float on the water surface. The melting point of sodium is also not high, about 97.81 ° C, and it is easy to melt into shiny balls when heated. Its conductivity is very good, because there are a large number of freely movable electrons inside, and under the action of an external electric field, the electrons move in a directional manner to form a current. The chemical properties of sodium are extremely active, and it easily reacts with oxygen in the air. The surface quickly darkens to produce sodium oxide. If heated, it burns violently, emitting a yellow flame and generating sodium peroxide.
The physical properties of the two are significantly different, and they are used reasonably in many chemical and industrial scenes according to their physical characteristics.
What are the precautions for Sodium P-Toluen Sulfonate in the production process?
Sodium and sodium p-toluenesulfonate should be paid attention to in the production process.
The purity of the first heavy material. Sodium is easy to phase with air and water, so it must be stored properly to prevent deliquescence and oxidation. Its shape should be carefully observed before use. If there is a qualitative change, it should not be used. Sodium p-toluenesulfonate should also be checked for its purity. The presence of impurities may hinder the reaction and reduce the yield.
The second is the reaction strip. The control of temperature is essential, and the reaction is sensitive to temperature, temperature discomfort, or slow reaction and yield drop, which is very important. Therefore, a precise temperature control device must be used to strictly adjust the temperature according to the square. The pressure should not be ignored either. Although there are many normal pressures, under certain circumstances, the pressure should be adjusted to promote the smooth operation.
Furthermore, stir evenly. Stirring can make the material mix evenly, and the mass transfer and heat transfer of the quick reaction can avoid local concentration difference and large temperature difference. Poor mixing, or the reaction is difficult to homogenize, and the yield and quality are affected. Therefore, choose a suitable stirrer and adjust it to a suitable stirring speed.
Safety is also a priority. Sodium is active and burns in case of water, so it must be avoided from contact with water during operation. Sodium toluenesulfonate may be irritating, and the operator should use protective equipment, such as gloves, goggles, etc., to prevent contact with the body. And it should be done in a well-ventilated place to avoid poisoning and smoke damage.
The last rule, the treatment of the product. After the reaction is completed, the product must be properly divided and pure. According to the product and impurity properties, select the appropriate method, such as crystallization, distillation, extraction, etc. After purification, the product should be qualified and used or sold for the next process.
In short, the production process of sodium and sodium p-toluenesulfonate, materials, reaction strips, stirring, safety and production physics, all need to be carefully controlled to ensure that the production is smooth and high-quality products are obtained.
What is the market price range for Sodium P-Toluen Sulfonate?
I don't know how to cut Sodium + P - Toluen + Sulfonate (sodium p-toluenesulfonate) in the market. However, if you want to know the market value of this product, you can do it on the chemical raw material trading platform and the supplier. Or go to the chemical market, or you can buy it.
Its price is often affected by multiple factors. First, the quality is the most important. Those with high quality and high quality often have the highest price; if there are a little more, the quality is good, and the quality is low. Second, the supply and demand also affect the price. If the market demand is strong and the supply is limited, the price may be low; if the supply is in demand, the merchant may reduce the price to promote it. Third, the cost of production cannot be ignored. The cost of raw materials, the complexity of manufacturing, energy consumption, etc., can all make the cost of production ripple, which will affect the market. Fourth, the cost of production and other uses also play a role. Proximity, decline, and other factors can all make the most cost-effective.
In order to obtain Sodium + P - Toluen + Sulfonate in the market, it is necessary to explore in multiple ways and take into account all factors.
What is the environmental impact of Sodium P-Toluen Sulfonate?
Sodium and sodium p-toluenesulfonate, the impact of these two on the environment should not be underestimated.
Let's talk about sodium first. Elemental sodium is extremely active. If it accidentally flows into natural water, it will react violently in contact with water, such as "floating, melting, swimming, ringing, and red", generating sodium hydroxide and hydrogen. Sodium hydroxide is highly corrosive and will change the pH of the water body, causing the pH value of the water body to rise sharply, destroying the aquatic ecological balance. Many aquatic organisms are difficult to adapt to this change, or cause their physiological disorders, or even death. And hydrogen is flammable. If it accumulates in a specific environment, it will encounter open flames and other incentives, or cause explosions, endangering the safety of the surrounding environment.
As for sodium p-toluenesulfonate, in the environment, first in the soil, it may be adsorbed on the surface of soil particles, affecting the soil pore structure, thereby hindering the gas exchange and water penetration in the soil, and interfering with the absorption of nutrients and water by plant roots. In water, although sodium p-toluenesulfonate has a certain solubility, it may be difficult to be rapidly degraded by microorganisms and will continue to accumulate in the water body. At high concentrations, it will change the physicochemical properties of water and affect the self-purification ability of the water body. And for aquatic organisms, it may be toxic, affecting the growth, reproduction and behavior of fish, plankton, etc., and even passing through the food chain, causing potential harm to higher trophic organisms. If released into the atmosphere, although the volatility is relatively low, it can still return to soil and water bodies as the atmosphere subsides, continuing to affect the ecological environment.
