Phosphoric acid tris(2-chloro-1-methylethyl) ester
1. Basic Information
Name: Phosphoric acid tris(2-chloro-1-methylethyl) ester
Alias: TCPP, Tris(1-chloro-2-propyl) phosphate
CAS No.: 13674-84-5
Molecular Formula: C9H18Cl3O4P
Molecular Weight: 327.57
Category: Halogenated phosphate flame retardant, plastic additive, polyurethane foam flame retardant, coating flame retardant auxiliary
2. Physical and Chemical Properties
Physical Properties
- Appearance: Colorless to pale yellow transparent oily liquid
- Odor: Faint mild organic ester odor
- Solubility: Miscible with polyether polyol, ethyl acetate, acetone, toluene, dichloromethane; slightly soluble in water
- Boiling Point: Decomposes above 240 ℃
- Density (20℃): 1.280–1.300 g/cm3
- Refractive Index nD20: 1.460–1.466
- Hygroscopy: Slightly hygroscopic
- Aqueous property: Stable in neutral cold water; slow hydrolysis under high temperature acid/alkali to generate hydrochloric acid and phosphate derivatives
Chemical Properties
- Molecular structure: Triester of phosphoric acid with three 2-chloro-1-methylethyl side chains, contains phosphorus and chlorine dual flame retardant elements
- Flame retardant mechanism: High temperature decomposes to form phosphorus carbonized layer, chlorine captures free radicals, synergistic flame retardant effect, low smoke
- Hydrolysis stability: Good hydrolysis resistance under normal processing temperature; long-term boiling with strong acid/alkali breaks ester bonds
- Plasticizing performance: Has certain plasticizing effect, improves material processing fluidity
- Thermal stability: Stable below 180 ℃; above 220 ℃ gradually decomposes and releases hydrogen chloride corrosive gas
- Photostability: Long-term ultraviolet irradiation will gradually deepen yellow color
- Compatibility: Excellent compatibility with rigid/flexible polyurethane foam, epoxy resin, PVC, unsaturated polyester; incompatible with strong alkaline aqueous solution at high temperature
3. Main Application Fields
1. Polyurethane Foam Flame Retardant (Core Application)
Universal flame retardant for rigid PU thermal insulation foam, soft furniture foam, filling foam; widely used in building insulation, refrigeration equipment, sofa mattresses
2. Plastic & Coating Flame Retardant Additive
Used in PVC resin, epoxy coating, unsaturated polyester resin to improve flame retardant grade and reduce smoke density
3. Adhesive & Sealant Auxiliary
Add flame retardant performance to building adhesives, waterproof sealants without significantly reducing bonding strength
4. Synthetic Leather & Textile Backing Coating
Flame retardant modifier for artificial leather, textile foam coating layer
