Procurenet
Short description

Diallyl Phthalate (DAP) is a multi-functional chemical compound (CAS No. 131-17-9) extensively utilized as a reactive monomer and plasticizer. Being a critical component in the manufacturing of varied resins, DAP exhibits stability at room temperature but turns active under heated conditions. Notable applications encompass the following:

  • Effectively used as a cross-linking agent for unsaturated resin
  • Serves as a reinforcing agent for fiber-reinforced resin

Though characterized by low toxicity, caution is advised against its inhalation or skin contact. It is environmentally friendly, completely biodegradable, and should be stored in well-ventilated, dry areas away from heat and light. Exclude contact with strong oxidants, acids, and alkali.

Diallyl Phthalate (DAP) - A Dependable Chemical Compound for Diverse Industrial Practices

Diallyl Phthalate (DAP) is a distinguished chemical compound with a unique molecular formula of C14H14O4 and a molecular weight of 246.3. Its identification number in the chemical world, known as the CAS number, is 131-17-9. The versatility of this compound lends itself to a multitude of industrial applications.

DAP, appearing as a colorless or light yellow transparent liquid, exhibits robustness in room temperatures, only reacting when heated with an initiator. This feature makes it a reliable option for controlled applications. It frequently functions as an integral reactive monomer, plasticizer, or inte al plasticizer, demonstrating its adaptability.

Distinguished Quality Parameters

Featuring a purity level of over 99.5%, DAP stands as a high-assay compound. It dispenses minimal moisture and acidity, adding to its stability. This compound has a boiling point of 157-165°C at 0.53kpa, a density of 1.120 ±0.003 (20°C), and a flash point of 163°C. Additionally, it manifests a freezing point of -70°C, demonstrating resistance to extreme temperatures.

DAP is water-insoluble, has a refractive index between 1.516 and 1.518 (25°C), and showcases a coefficient of heat expansion between 20-40°C of 0.00076/°C.

Vast Application Spectrum

As a crossing agent and plasticizer of unsaturated resin, DAP is broadly employed. Its application ranges from an inte al plasticizer for PVC resin, a reinforcing agent of fiber-reinforced resin to an auxiliary crossing agent of synthetic rubber. DAP also finds application in the synthesis of acrylic resin and the production of unsaturated polyester resin and self-polymerization polymer.

Environmental Impact and Safety Guidelines

DAP is low-toxicity; however, prolonged exposure could lead to tissue and liver injuries. Accordingly, precautions should be taken to prevent any inhalation or contact incident. If spillage occurs, DAP can be safely contained using sand or inert materials.

With complete biodegradability, DAP does not pose any significant environmental hazards. It should be stored in a dry, ventilated location away from light and heat. These factors contribute to the relevance of DAP as a prime choice in various industries' raw materials.
