Chemical formula. C 18 H 15 Cl 2 P Molar mass: 333.19 g/mol Melting point: 176 °C (349 °F; 449 K) [1] 85-100 °C [2] ... Phosphorus trichloride Phosphorus pentachloride
The compound was probably prepared in the 1850s by combining phosphorus trichloride and ethanol, but intentional preparations came later. It arises as follows: [2] PCl 3 + 3 C 2 H 5 OH → (C 2 H 5 O) 2 P(O)H + 2 HCl + C 2 H 5 Cl
P 4 O 6 + 6 H 2 O → 4 H 3 PO 3. It reacts with hydrogen chloride to form H 3 PO 3 and phosphorus trichloride. P 4 O 6 + 6 HCl → 2 H 3 PO 3 + 2 PCl 3. With chlorine or bromine it forms the corresponding phosphoryl halide, and it reacts with iodine in a sealed tube to form diphosphorus tetraiodide. [1] P 4 O 6 reacts with ozone at 195 K to ...
Chlorodiphenylphosphine is an organophosphorus compound with the formula (C 6 H 5) 2 PCl, abbreviated Ph 2 PCl. It is a colourless oily liquid with a pungent odor that is often described as being garlic-like and detectable even in the ppb range. It is useful reagent for introducing the Ph 2 P group into molecules, which includes many ligands. [2]
