  Lead halophenoxides and carbonylation catalyst and method for preparing and employing them - Patent 6310229
Lead halophenoxides, especially bromophenoxides, are prepared by the reaction of lead(II) oxides with a hydroxyaromatic compound such as phenol and a chloride or bromide salt such as an alkali metal bromide, a tetraalkylammonium bromide or a bexaalkylguanidinium bromide.
When the bromide or chloride salt is an inorganic salt such as sodium bromide, the reaction is preferably facilitated by the presence of an electron-donating compound, especially a nitrile such as acetonitrile or a polyether such as diethylene glycol dimethyl ether (diglyme) or tetraethylene glycol dimethyl ether (tetraglyme).
Lead(II) oxide (PbO), 2.715 g, was dissolved in 10 ml of phenol (PhOH) at 100.degree.

Hydrochloric acid, or aqueous hydrogen chloride forms an ionic solution when dissolved in water, yet is gaseous in its pure form, like a molecular compound.
Calcium chloride is also ionic, as it is composed of a metal and a non-metal.
In gaseous hydrogen chloride, which is a molecule (all common gases are molecules) hydrogen must have the properties of a non-metal.
