Dense halogenated organic solvents

3 Properties of Heavy Liquids (Heavy Media) 20.3.3.1 Dense Halogenated Organic Solvents 

Solubility into water (20 C) 12.5 g/L also soluble in ethanol, diethyl ether, and acetone. 

Soluble into ethanol, acetone, diethyl ether, benzene. Iodoform and iodine can be dissolved in it to increase density. It decomposes into free iodine especially when exposed to sunlight. 

Dense and moderately viscous liquids with the odor of camphor and iodoform. Insoluble in water but can be diluted with carbon tetrachloride, benzene, toluene, acetone, diethyl ether, chloroform, aniline and glacial acetic acid. Prepared by passing acetylene into cooled bromine. With a flash point of 335°C, it decomposes on heating at 235°C. Irritating and narcotic.
