Physical and Chemical Properties
HCB is a white crystalline solid that has negligible solubility in water (0.00000002 M) and variable solubility in different organic solvents. It is most soluble in halogenated solvents like chloroform (approx 0.03 M) less soluble in esters and hydrocarbons ((approx 0.020 M), and even less soluble in short chain alcohols (0.002-0.006 M). Its vapour pressure is 1.09×10−5 mmHg (1.45 mPa) at 20 °C. Its flash point is 242 °C and it sublimes at 322 °C.

Famous quotes containing the words physical, chemical and/or properties:
“There is nothing that man fears more than the touch of the unknown. He wants to see what is reaching towards him, and to be able to recognize or at least classify it. Man always tends to avoid physical contact with anything strange.”
—Elias Canetti (b. 1905)
“We do not want actions, but men; not a chemical drop of water, but rain; the spirit that sheds and showers actions, countless, endless actions.”
