The Phosphorus trifluoride, with the CAS registry number 7783-55-3 and EINECS registry number 232-008-7, is also called trifluorophosphin. It is a kind of moisture sensitive chemical, and the molecular formula of this chemical is F3P. What's more, it is a colorless and odorless gas and main use is as a ligand in metal complexes.
The physical properties of Phosphorus trifluoride are as following: (1)ACD/LogP: 3.05; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 3.05; (4)ACD/LogD (pH 7.4): 3.05; (5)ACD/BCF (pH 5.5): 123.29; (6)ACD/BCF (pH 7.4): 123.29; (7)#H bond acceptors: 0; (8)#H bond donors: 0; (9)#Freely Rotating Bonds: 0; (10)Polar Surface Area: 13.59 Å2; (11)Enthalpy of Vaporization: 16.5 kJ/mol; (12)Boiling Point: °C at 760 mmHg; (13)Vapour Pressure: 40800 mmHg at 25°C.
Preparation of Phosphorus trifluoride: It is usually prepared from phosphorus trichloride via halogen exchange using various fluorides such as hydrogen fluoride, calcium fluoride, arsenic trifluoride, antimony trifluoride, or zinc fluoride:
2 PCl3 + 3 ZnF2 → 2 PF3 + 3 ZnCl2
You should be cautious while dealing with this chemical. It reacts violently with water, and if contact with acids will liberate very toxic gas. And it may also cause burns. Therefore, you had better take the following instructions: Keep container tightly closed in a cool place; Keep container in a well-ventilated place; In case of insufficient ventilation, wear suitable respiratory equipment; In case of accident or if you feel unwell, seek medical advice immediately (show label where possible). In addition, its toxicity is due to its binding with the iron in blood hemoglobin in a similar way to carbon monoxide.
You can still convert the following datas into molecular structure:
(1)SMILES: FP(F)F
(2)InChI: InChI=1/F3P/c1-4(2)3
(3)InChIKey: WKFBZNUBXWCCHG-UHFFFAOYAK
