Naphthalene Powder Extra Pure
Original price was: $ 18.00.$ 17.78Current price is: $ 17.78.
Naphthalene Powder Extra Pure is a fine, white to pale crystalline powder composed of high-purity naphthalene (C₁₀H₈), valued for its consistent quality and volatile aromatic properties. This form is particularly suitable for laboratory use, where controlled dosing and faster sublimation are required. The powder is widely utilized in organic synthesis, standardization experiments, and melting point calibration, owing to its stable molecular structure and high sublimation rate.
In industrial and technical contexts, naphthalene powder serves as a precursor in dye manufacturing, plasticizer production, and pesticide formulation. It is also used as a fumigant for controlling pests in storage environments, similar to its use in ball form, but with faster release due to the increased surface area. Despite its utility, the powder must be handled with care—used in well-ventilated areas, kept away from ignition sources, and stored in sealed containers—due to its flammability and potential health effects from prolonged inhalation.
Naphthalene Powder Extra Pure
Primary Uses
- Reactant in Organic Chemical Synthesis
- Used as a starting material or precursor for the industrial and laboratory-scale synthesis of compounds like phthalic anhydride (via catalytic oxidation), sulfonated naphthalene (used in concrete plasticizers), and azo dyes. The powder form provides a high surface area, leading to faster and more efficient reaction rates.
- Raw Material for Formulating Pesticides
- Serves as the active ingredient in the manufacturing of moth repellents, soil fumigants, and other pesticide products. The fine powder is easily mixed with other carriers, binders, and co-fumigants to create pellets, cakes, or dust formulations.
- Fuel and Combustion Additive
- Incorporated into solid fuel propellants and pyrotechnic compositions to increase the fuel content and control burning characteristics. The powder’s high surface area allows for rapid, controlled combustion. It is also studied in fuel additives for soot suppression.
- Intermediate in Dye and Pigment Production
- Acts as a fundamental building block in the chemical industry for producing a wide range of synthetic dyes, particularly azo dyes, and organic pigments. Its powdered state is optimal for handling in large-scale chemical processes like diazotization and coupling reactions.
Secondary Uses
- Teaching Tool for Purification Techniques
- An excellent substance for teaching laboratory techniques such as re-crystallization (using solvents like ethanol) and sublimation due to its “extra pure” grade and well-defined crystal structure upon cooling, allowing students to practice and observe purification methods.
- Solvent for Specific Industrial Applications
- Used as a low-cost, volatile solvent for some organic compounds in specific industrial applications, such as the formulation of certain oils, resins, or in the production of carbonaceous materials.
- Study of Sublimation Kinetics and Crystal Growth
- The powder form is ideal for quantitative experiments studying the kinetics of sublimation (mass loss over time) under different temperatures and pressures. It is also used to seed and study the growth of large, pure naphthalene crystals.
- Component in Composite Materials and Plastics
- Investigated and used as a filler or organic modifier in some polymer composites and as a raw material in the synthesis of certain high-performance plastics and resins, such as polyvinyl chloride (PVC) stabilizers and epoxy hardeners.
