Isopropylated triphenyl phosphate (IPPP) Introduction

Isopropylated triphenyl phosphate (IPPP) Introduction

Isopropylated Triphenyl Phosphate (IPPP) is an organophosphorus compound, commonly used as a flame retardant and plasticizer. The following is a detailed introduction:

1. Chemical structure:
   Molecular formula: C21H21O4P
   Structure: IPPP is an isopropylated derivative of triphenyl phosphate, with hydrogen on the benzene ring replaced by isopropyl.
2. Physical properties:
   Appearance: colorless or light yellow liquid
   Boiling point: high, the specific value depends on the degree of substitution
   Solubility: easily soluble in organic solvents, difficult to dissolve in water
3. Chemical properties:
   Stability: chemically stable, heat-resistant and hydrolysis-resistant
   Reactivity: can participate in esterification, substitution and other reactions
4. Application:
   Flame retardant: widely used in flame retardant materials such as plastics, rubber, and textiles
   Plasticizer: used in plastics such as PVC to improve flexibility and processing performance
   Other uses: as a lubricant additive and hydraulic oil component
5. Safety:
   Toxicity: low toxicity, but long-term contact should be avoided
   Environmental impact: not easy to degrade, may be harmful to aquatic organisms
6. Regulations:
   Restrictions on use: some regions have strict regulations on its use, and relevant regulations must be observed
   Synthesis method
   Synthesis route: prepared by reacting triphenyl phosphate with isopropanol under acidic conditions

Summary:

IPPP is an important organophosphorus compound, which is widely used in flame retardant and plasticizer fields. However, attention should be paid to its safety and environmental impact during use.
