The product we are focusing on is Factory Supply Sodium p - Toluene Sulfonic 98% with CAS number 657 - 84 - 1. This product is typically supplied at a purity of 98%, which ensures high - quality performance in various applications. The chemical formula of sodium p - toluene sulfonic is C₇H₇NaO₃S. It appears as a white to off - white crystalline powder. It has good solubility in water, allowing it to be easily incorporated into aqueous systems. The melting point of this compound is around 106 - 107°C. When handling, it should be stored in a cool, dry place away from direct sunlight and sources of heat to maintain its chemical stability.
Sodium p - toluene sulfonic has a wide range of uses across different industries. In the chemical industry, it serves as a catalyst in many organic synthesis reactions. For example, it can accelerate esterification reactions, which are crucial in the production of esters used in fragrances, flavors, and plasticizers. In the textile industry, it is used as a leveling agent. It helps to ensure uniform dyeing of fabrics, preventing uneven color distribution and resulting in high - quality, consistent - colored textiles. Additionally, in the electroplating industry, it can be used as an additive in electroplating baths. It improves the quality of the electroplated layer, enhancing the adhesion and smoothness of the metal coating on the substrate.
When using sodium p - toluene sulfonic, proper safety precautions should be taken. Wear appropriate protective equipment such as gloves and safety glasses. For its use as a catalyst in organic synthesis, the appropriate amount of sodium p - toluene sulfonic should be accurately weighed according to the reaction requirements. Usually, it is added to the reaction mixture at the appropriate stage of the reaction. For example, in an esterification reaction, it can be added at the beginning along with the reactants. In the textile industry, it is typically dissolved in water to form a solution, and then the fabric is immersed in this solution during the dyeing process. The concentration of the solution needs to be carefully controlled based on the type of fabric and the desired dyeing effect. In electroplating, it is added to the electroplating bath in a specific proportion, and proper agitation of the bath is required to ensure uniform distribution.
Case 1: Organic Synthesis in a Fragrance Factory
A fragrance manufacturing company was producing a new ester - based fragrance. They were using a traditional catalyst, but the reaction rate was slow, and the yield was low. After switching to sodium p - toluene sulfonic at a purity of 98%, the reaction time was significantly reduced from 8 hours to 3 hours. The yield also increased from 70% to 90%. This not only improved the production efficiency but also reduced the production cost.
Case 2: Textile Dyeing in a Textile Mill
A textile mill was facing problems with uneven dyeing of cotton fabrics. They introduced sodium p - toluene sulfonic as a leveling agent. By carefully adjusting the concentration of the sodium p - toluene sulfonic solution and the immersion time of the fabric, they were able to achieve uniform dyeing across all batches of cotton fabrics. The rejection rate due to uneven color was reduced from 15% to less than 3%, greatly improving the product quality and customer satisfaction.
Case 3: Electroplating in an Electronic Components Factory
An electronic components factory was electroplating copper on small electronic parts. The electroplated layer had poor adhesion and was prone to peeling off. After adding sodium p - toluene sulfonic to the electroplating bath, the quality of the electroplated layer improved significantly. The adhesion strength increased, and the surface smoothness of the electroplated parts was enhanced, meeting the high - precision requirements of the electronic components.
