| Product Introduction: | Triphenylphosphine is a fundamental raw material for rhodium-phosphine complex catalysts and has broad applications in the domestic petrochemical industry. It is also used in the pharmaceutical industry, organic synthesis, analysis, and other fields. Additionally, it serves as a brightener in dye processes, an antioxidant in the development of color films, a stabilizer for polyepoxidation, and an analytical reagent. Also known as triphenylphosphine, triphenylphosphorus, phosphine triphenyl, triphenyl phosphate, etc., it was referred to as triarylphosphines in older literature. English name: triphenylphosphine Abbreviation: PPh3 Molecular formula: C18H15P (a triphenyl-substituted phosphine) Molecular weight: 262.30 CAS number: 603-35-0 EINECS number: 210-036-0 Molecular geometry: Trigonal pyramidal Appearance: White loose powder. Solubility: Soluble in alcohol, benzene, and chloroform; slightly soluble in esters; almost insoluble in water. Density (relative to water): 1.194 (25°C) Melting point: 80.5°C. Boiling point: 377°C (91 kPa). Flash point (open cup): 180°C. Applications: Triphenylphosphine is a fundamental raw material for rhodium-phosphine complex catalysts and has broad applications in the domestic petrochemical industry. It is also used in the pharmaceutical industry, organic synthesis, analysis, and other fields. Additionally, it serves as a brightener in dye processes, an antioxidant in the development of color films, a stabilizer for polyepoxidation, and an analytical reagent. 1. Used in organic synthesis, polymerization initiators, raw material for antibiotic drugs like clindamycin, and as a standard sample for phosphorus determination in organic microanalysis. 2. Preparation of palladium, iridium, rhodium, nickel, and other complex catalysts; Wittig reagent; deoxygenation of triphenylphosphine dihalides (pyridine N-oxide, nitrosobenzene, hydroperoxides); desulfurization and debromination reagents. Converts α-bromonitro compounds to nitriles. Reacts with aliphatic diazo compounds to synthesize α-ketoaldehydes and β-keto esters. Facilitates Beckmann rearrangement. Dequaternization of pyridinium salts. Used in various syntheses with bromine, iodine, carbon tetrachloride (bromide), N-bromosuccinimide, etc. 3. Triphenylphosphine is a commonly used reducing agent, with reactions typically driven by the formation of triphenylphosphine oxide (a thermodynamically favorable reaction). It is also widely employed as a ligand in metal catalysts. Storage Method: Storage precautions: Store in a cool, well-ventilated warehouse. Keep away from fire and heat sources. Ensure packaging is sealed. Store separately from oxidizers and food chemicals; avoid mixed storage. Equip with appropriate types and quantities of fire-fighting equipment. The storage area should have suitable materials to contain leaks. |
