Chemische Eigenschaften

Anwendungen

Triphenylphosphine is used as a support for nickel, rhenium and rhodium in hydrogenation, in dimerization of alkenes and in hydroformylation. It is also used for the halogenation of carboxylic acid and alkanes in carbon tetrachloride, addition of iodine in DMF esterifies primary and secondary alcohols to their respective formate esters and in the Mitsunobu and the Wittig reactions.

Bemerkungen

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Incompatible with oxidizing agents.
