How is Zinc Dodecyl Stearate produced?
Preparation technology of zinc stearate comprises the following steps that 1, glyceryl tristearate and water are under the action of a catalyst and an antioxidant; 2, zinc oxide and a catalyst are added stepwise, condensing, dewatering and salt-forming are conducted, and zinc stearate is synthesized.
Application of Zinc Dodecyl Stearate:
Zinc Dodecyl Stearate is widely used in lubricant, stabilizer, decolorizing agent and thickener. Used in the process of release molding of polystyrene resin, phenolic resin, amino resin. It is an excellent rubber and plastic auxiliaries, also are the surfactant and softener.
Zinc dodecyl stearate is a common surfactant and polymer modifier with various industrial applications. This article will provide a detailed introduction to the definition, application scenarios, chemical and physical properties, production methods, and future development directions of zinc dodecyl stearate.
In daily chemicals, textiles, plastics, coatings, etc., zinc dodecyl stearate is widely used in detergents, wetting agents, emulsifiers, and dispersants. As an efficient surfactant, it can reduce the surface tension of liquids and improve their wettability. In addition, zinc dodecyl stearate can also be used as a polymer modifier to improve the processing performance, heat resistance, weather resistance, and mechanical strength of materials.
Regarding chemical properties, zinc dodecyl stearate has high acid and saponification values. The acid value indicates the content of free acids in it. In contrast, the saponification value represents the amount of potassium salt generated by the saponification reaction with potassium hydroxide. These indicators directly affect zinc dodecyl stearate's chemical reactivity and product quality.
Regarding physical properties, zinc dodecyl stearate has good melting point and solubility characteristics. The melting point can reflect its purity and crystallinity, while solubility is closely related to its solubility and application performance in solvents. In addition, its expansion coefficient is small, making it suitable for special polymer modification situations that require controlled expansion.
Regarding production methods, zinc dodecyl stearate is mainly prepared by saponification reaction between stearic acid and zinc salt. Saponification reactions generally use sodium hydroxide or potassium hydroxide as catalysts. Factors such as saponification reaction temperature, reaction time, and catalyst dosage will impact production efficiency and product quality. The product obtained through the saponification reaction is then neutralized to obtain zinc dodecyl stearate with an ideal acid-base value. Finally, excess stearic acid is removed through thermal decomposition to obtain high-purity zinc dodecyl stearate.
