The product we are introducing here is Factory Supply Sodium p - toluene Sulfonic 88%. The CAS number of this product is 657 - 84 - 1. The “88%” indicates the purity level of the product, which means that in each batch of the product, 88% of the content is sodium p - toluene sulfonic, and the remaining 12% may consist of some impurities or additives depending on the manufacturing process. Sodium p - toluene sulfonic is a white or off - white crystalline powder. It is soluble in water, alcohol, and other polar solvents. It has relatively stable chemical properties under normal conditions but may react under extreme temperature or with certain strong oxidants.
1. In the field of chemical synthesis, sodium p - toluene sulfonic is widely used as a catalyst. It can accelerate the reaction rate of many organic synthesis reactions, such as esterification reactions. In the production of various esters, adding an appropriate amount of sodium p - toluene sulfonic can significantly shorten the reaction time and improve the yield of the product.
2. It is also used in the electroplating industry. As an additive in electroplating solutions, it can improve the quality of the electroplated layer, making the coating more uniform, smooth, and corrosion - resistant.
3. In the printing and dyeing industry, sodium p - toluene sulfonic can be used as a leveling agent. It helps the dyes to be evenly distributed on the fabric, thereby improving the color fastness and color uniformity of the dyed fabric.
1. Storage: Store the product in a cool, dry place away from direct sunlight and sources of heat. Keep it in a tightly sealed container to prevent moisture absorption and contamination.
2. Handling: When handling sodium p - toluene sulfonic, wear appropriate personal protective equipment, such as gloves and goggles. Avoid inhalation of dust and direct contact with skin and eyes. In case of contact, immediately rinse with plenty of water and seek medical attention if necessary.
3. Dosage determination: The dosage of sodium p - toluene sulfonic depends on the specific application. In chemical synthesis, it is usually added in a certain proportion according to the reaction scale and the nature of the reactants. In electroplating and printing and dyeing, it is necessary to adjust the dosage according to the process requirements and the quality of the raw materials. It is recommended to conduct small - scale tests first to determine the optimal dosage.
1. Chemical synthesis case: A chemical factory was producing a certain type of ester. Before using sodium p - toluene sulfonic, the reaction time was about 8 hours, and the yield was only around 70%. After adding an appropriate amount of sodium p - toluene sulfonic as a catalyst, the reaction time was shortened to 3 hours, and the yield increased to 90%. This not only improved the production efficiency but also reduced the production cost.
2. Electroplating case: A metal processing enterprise was facing the problem of uneven electroplated layers on its products. After adding sodium p - toluene sulfonic to the electroplating solution, the surface of the electroplated products became smooth and uniform, and the corrosion resistance was significantly improved. The rejection rate of the products decreased from 15% to 3%.
3. Printing and dyeing case: A textile factory was using a new type of dye, but the color of the dyed fabric was uneven. By adding sodium p - toluene sulfonic as a leveling agent, the color uniformity of the fabric was greatly improved. The color fastness also met the market requirements, which enhanced the competitiveness of the products in the market.
