无气味。摩擦能发光。易溶于乙醚，溶于氯仿、乙酸和苯，微溶于乙醇，几乎不溶于水。低毒，半数致死量(大鼠，经口)800mg/kg。有刺激性。 用于有机合成，聚合引发剂，抗菌素类药物氯洁霉素的原料，有机微量分析测定磷的标准样品。 三苯基膦也称 PPH3，是一种有机磷化合物。易与铂金属基盐形成络合物。 Rhodium and triphenylphosphine catalyst system has been used for the hydroformylation of soybean, safflower and linseed oils and their methyl esters. Polymer supported triphenylphosphine has been reported to efficiently catalyze the γ-addition of pronucleophiles to alkynoate. Triphenylphosphine reacts with hydrated ruthenium trichloride in methanol to afford [RuCl2(PPh3)4], [RuCl2(PPh3)3] and [RuCl3(PPh3)2CH3OH].It participates in the Heck reaction of 4-bromoanisole and ethyl acrylate in ionic liquids.
