anol and titanium tetrachloride in the presence of amm~ nia.~ This siloxy titane is a water- whiteJ mobile liquid which boils at 106'at 7 mm., almost the same boiling point as t-butoxy titanate, 108'at 10 mm. 8 In this connection it is interesting to note that hexamethyldisiloxane boils at 100'and di-t-butyl ether boils at 101 O, lo both at atmospheric pressure.
