Benzyltriphenylphosphonium Bromide (BTPPB) CAS 1449-46-3

Physicochemical properties

Application Areas

Phase transfer catalyst: As a quaternary phosphonium salt phase transfer catalyst in organic synthesis, it promotes the reaction between aqueous and organic phases, improves reaction efficiency and product yield

Storage conditions

Standard conditions: Store in a cool, dry, well ventilated warehouse and keep away from sources of fire.
Special requirement: It needs to be stored separately from the oxidant to avoid mixing storage. Containers should be moisture-proof and leak proof, and it is recommended to use inert gas (such as nitrogen) for protection.

Safety precautions

Operation protection:
Wear a dust mask (to prevent inhalation of solid powder), nitrile gloves (to avoid skin contact), and goggles (to prevent powder from splashing into the eyes) during operation, and conduct the experiment in a well ventilated laboratory or fume hood.
Avoid mixing with strong oxidants (such as hydrogen peroxide) and strong bases (such as sodium hydroxide) to prevent chemical reactions from producing toxic gases (such as hydrogen bromide).
Leakage disposal: Collect a small amount of leakage with clean dry cloth or filter paper, and put it in a sealed bag (marked as “hazardous waste”); A large amount of leakage needs to be covered with sand to avoid dust, and then transferred to a dedicated container for disposal. It is prohibited to flush into the sewer.
