说明

一般描述

Red phosphorus is the most common allotrope of phosphorus. It exists in an amorphous form and found to be more stable than white phosphorus. It is used in organic synthesis and chemical warfare including igniters, incendiaries, screening smoke ammunition and smoke signal. Red phosphorus is also used as a flame retardant in many thermoplastics and thermosetting plastics.

应用

Red phosphorus can be used as a:

• Photocatalyst for the formation of H₂ from water.
• Catalyst in the synthesis of tris(2-pyridyl)phosphine by reacting with 2-bromopyridine in the presence of a base.
• Flame retardant along with aluminum oxide in recycled poly(ethylene terephthalate).
• Anode material in combination with carbon composites for sodium-ion batteries.
