DOT Classification: 8; Label: Corrosive

Phosphorus oxybromide Specification

Phosphorus oxybromide(CAS NO.7789-59-5), its Synonyms are Phosphoryl tribromide; Tribromophosphorus oxide; Phosphoric tribromide. It is a acolorless crystalline solid or liquid if heated above 133° F with a pungent odor. Phosphorus oxybromide is commonly heated and shipped in a molten state. Soluble in water, but, decomposed by water to hydrobromic and phosphoric acid with evolution of heat. Reacts with organic materials to cause fire. Evolves highly toxic and corrosive gases when exposed to fire. Corrosive to metals and tissue. Used to make other chemicals. Phosphorus oxybromide is mainly used as inorganic phosphorus flame retardants, phosphorus-containing catalyst,etc.

Physical properties about Phosphorus oxybromide are: (1)ACD/LogP: 1.51; (2)ACD/LogD (pH 5.5): 1.51; (3)ACD/LogD (pH 7.4): 1.51; (4)ACD/BCF (pH 5.5): 8.28; (5)ACD/BCF (pH 7.4): 8.28; (6)#H bond acceptors: 1; (7)Index of Refraction: 1.613; (8)Molar Refractivity: 32.118 cm³; (9)Molar Volume: 92.228 cm³; (10)Polarizability: 12.733 10-24cm³; (11)Surface Tension: 63.8219985961914 dyne/cm; (12)Density: 3.109 g/cm³; (13)Boiling Point: 189.5 °C at 760 mmHg

When you are using this chemical, please be cautious about it as the following:
1. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice;
2. Wear suitable protective clothing, gloves and eye/face protection;
3. In case of fire, use ... (indicate in the space the precise type of fire-fighting equipment. If water increases the risk add - Never use water);
4. In case of accident or if you feel unwell, seek medical advice immediately (show label where possible);
5. Keep container tightly closed and dry;

You can still convert the following datas into molecular structure:
