THE CARBON COMPOUNDS, 348
action of acids, it is decomposed into benzene and a mercuric salt'
and when it is heated with iodine, according to the proportion of the
two bodies present, either iodobenzene and phenylmercuric iodide
C 6 H 1
j J- Hg are formed, or iodobenzene and mercuric iodide.
CHI
Stannifrphcnyl Triethide ,Q A . 6 ^ Sn is obtained by the action ol
sodium upon a mixture of bromobenzene and triethyl-stannic iodide.
It is a colourless, strongly refractive liquid, boiling at 254°; its vapour
slowly absorbs oxygen. By the action of iodine, it is resolved into
iodobenzene and triethyl-stannic iodide.
ADDITIVE 'COMPdDMDS OF BENZENE.
Benzene HexacMoride CpHgCl^ is obtained, by the action of chlorine
on benzene, in the sunshine or at the boiling-point, in colourless
crystals, melting at lS'T, and boiling, with partial decomposition, at
288°. On heating it -with alkalis, it is resolved into hydrochloric
acid and trichlorobenzene.
A similar compound is Benzene Eexabromide CjHjBr,.
Bmxm Triehlorhydrin CLHJGgXOHJg is formed by shaking
benzene with aqueous hydrochlorous acid. It is slightly soluble in
water, and freely in alcohol and benzene, and crystallizes at a low
temperature in small plates, melting at 10°. By the action of a dilute
solution of sodium carbonate, an amorphous deliquescent mass called
phenose C6H0(OH)6 is obtained, which, as well as the triehlorhydrin,
yields, when heated with hydriodic acid, mdniodobenzolene COHUI, a
heavy, colourless liquid, which boils without decomposition.
Tricliforophenomalic Add C0H0CL05 is produced, together with
oxalio acid, chlorinated benzenes, and quinones,
