Reactivity: Red-P reacts with water vapor and oxygen in air to form extremely toxic phosphine gas, phosphorus oxyacids, white phosphorus, and phosphoric acid. These reactions are accelerated by higher temperatures or trace amounts of metals, including those found in household plumbing.
How do you make phenylacetone?
Phenylacetone can also be produced from many other chemicals. For example, phenylacetic acid is distilled with lead acetate to yield phenylacetone.
