| Use | Methyl triphenyl iodide is a halogen-containing flame retardant. At present, halogen-containing flame retardants are widely used organic flame retardants with excellent flame retardant properties. Methyl triphenyl phosphorus iodide is an aromatic Quaternary phosphine salt, which is used as a catalyst for pharmaceutical intermediates and a heat stabilizer for polycarbonate, a raw material for food packaging. Used as a precursor for wittig reagents. |

2065-66-9 - Uses and synthesis methods
Preparation
triphenylphosphine (0.0035mol), ammonium iodide (0.00355mol) and trimethyl orthoformate (1.5ml) were sequentially added to the two-neck flask, and stirrers were added. Heat reflux at 110 ℃ for 1 hour. After the reaction is completed, cool to room temperature, evaporate under reduced pressure to remove the solvent, and recrystallize with dichloromethane, ethyl acetate and petroleum ether. The obtained solid is washed with ethyl acetate and petroleum ether, and the white solid obtained after suction filtration is moved to a vacuum oven at 60°C for overnight drying, and the obtained solid quaternary phosphonium salt flame retardant (PFR-18) is methyl triphenyl Iodide, the yield is about 92%.
use
Hydrogenation accelerator, epoxy resin hardening accelerator; olefin polymerization catalyst, polyurea catalyst, hydrogenation reforming catalyst, etc.; heat resistance improver for aromatic polyester resin; heat stabilizer for polycarbonate; plastic processing performance improver; metal in weight removal oil, etc.; phase conversion agent for rubber products; intermediates for long-acting and efficient pesticide synthesis, etc.
