Шаблон:Short description Шаблон:Chembox
1,1,1,3,3,3-Hexachloropropane is a compound of chlorine, hydrogen, and carbon, with chemical formula Шаблон:Chem2, specifically Шаблон:Chem2. Its molecule can be described as that of propane with chlorine atoms substituted for the six hydrogen atoms on the extremal carbons.[1]
History and properties
There are 29 chlorinated derivatives of propane (four of them being hexachloropropanes, with the formula Шаблон:Chem2). This was the last one of them to be synthesized—by A. W. Davis and A. M. Whaley—in 1950.[2]
1,1,1,3,3,3-Hexachloropropane is a liquid that boils at 206 °C.[3][2] Its boiling point is significantly higher than expected based on estimations from various molecular parameters.[4][5][6]
Production
The original synthesis by Davis and Whaley obtained the compound by reacting 1,1,3,3-tetrachloropropane and/or 1,1,1,3-tetrachloropropane with chlorine at 80-100 °C, through 1,1,1,3,3-pentachloropropane as an intermediate step.[2]
The compound can be produced quantitatively also by reacting carbon tetrachloride Шаблон:Chem2 and 1,1-dichloroethene Шаблон:Chem2 at 80-150 °C, with a copper-based catalyst, such as copper(I) chloride or copper(II) chloride, and possibly an amine as co-catalyst.[7][8][9][10][11][12][13][14] The same process can generate higher chlorinated alkanes of the form Шаблон:Chem2.[7][11]
Applications
The compound has been considered as an intermediate in the manufacture of 1,1,1,3,3,3-hexafluoropropane, through reaction with hydrogen fluoride.[15][16][17][18]
Safety
A 2001 study found that the compound had significant effects on rat fetuses when inhaled at 25 ppm. The LDШаблон:Sub (injection, rats) was found to be 827 mg/kg.[19][20]
