The product ethylhexanoic acid zinc salt, with the CAS number 136 - 53 - 8, is a chemical compound that is commonly supplied by factories. It is a zinc salt of 2 - ethylhexanoic acid. The molecular formula of this compound is C₁₆H₃₀O₄Zn. It appears as a white to pale - yellow powder or granular solid. The density of ethylhexanoic acid zinc salt is approximately 1.09 g/cm³. The melting point of this product is around 85 - 90 °C. It is sparingly soluble in water but soluble in organic solvents such as ethanol, acetone, and toluene. Quality control during the manufacturing process ensures a high - purity product, typically with a purity level of 98% or above.
1. **Catalyst in Chemical Reactions**: Ethylhexanoic acid zinc salt is widely used as a catalyst in various chemical reactions. It can accelerate the reaction rate, improve the reaction efficiency, and increase the yield of the desired products. For example, in the synthesis of polymers, it can help in the polymerization process by promoting the reaction between monomers.
2. **Drying Agent in Coatings**: In the coatings industry, it serves as a drying agent. It can speed up the drying process of paints, varnishes, and other coatings. This is especially useful in industrial coating applications where rapid drying is required to increase production efficiency.
3. **Stabilizer in Plastics**: As a stabilizer in plastics, it can improve the thermal stability and weather resistance of plastic products. It helps to prevent the degradation of plastics under high - temperature conditions or when exposed to sunlight, thus extending the service life of plastic products.
1. **Catalyst Usage**: When using ethylhexanoic acid zinc salt as a catalyst, it should be added in an appropriate amount according to the specific reaction requirements. Usually, it is added at the beginning of the reaction. The reaction temperature and pressure should be carefully controlled. After the reaction is completed, the catalyst can be separated from the reaction mixture by appropriate methods such as filtration or extraction.
2. **Drying Agent in Coatings**: In coating applications, it is mixed with the coating formulation. The amount of addition depends on the type of coating, the drying requirements, and the environmental conditions. It is recommended to conduct small - scale tests first to determine the optimal dosage. After mixing, the coating can be applied to the substrate using conventional coating methods such as spraying, brushing, or dipping.
3. **Stabilizer in Plastics**: When used as a stabilizer in plastics, it is incorporated into the plastic resin during the plastic processing. The addition process should be carried out evenly to ensure that the stabilizer is well - distributed in the plastic matrix. The processing temperature and time should also be adjusted according to the characteristics of the plastic and the stabilizer.
**Case 1: Polymerization Reaction**
A chemical company was engaged in the production of a certain type of polymer. They used ethylhexanoic acid zinc salt as a catalyst. By adding an appropriate amount of the catalyst at the beginning of the reaction, they were able to reduce the reaction time from 6 hours to 4 hours. The yield of the polymer increased from 80% to 90%. This not only improved the production efficiency but also reduced the production cost.
**Case 2: Coating Application**
A furniture manufacturing company was using a slow - drying paint for their products. After adding ethylhexanoic acid zinc salt as a drying agent, the drying time of the paint was reduced from 24 hours to 12 hours. This allowed the company to increase the production volume significantly. Moreover, the quality of the coating surface was improved, with fewer defects such as dust adhesion during the drying process.
**Case 3: Plastic Stabilization**
A plastic products manufacturer was producing plastic pipes. They added ethylhexanoic acid zinc salt as a stabilizer. After long - term exposure to sunlight and high - temperature conditions, the plastic pipes showed less degradation compared to the pipes without the stabilizer. The pipes maintained their mechanical properties and appearance for a longer time, which increased the customer satisfaction and the market competitiveness of the products.
