Borate synonyms

Heated with sulphuric acid and with nitric acid it is oxidized to boric acid, whilst on fusion with alkaline carbonates and hydroxides it gives a borate of the alkali metal.

Many organic compounds of boron are known; thus, from the action of the trichloride on ethyl alcohol or on methyl alcohol, ethyl borate B(OC2H5)3 and methyl borate B(OCH 3) 3 are obtained.

By the action of zinc methyl on ethyl borate, in the requisite proportions, boron trimethyl is obtained, thus :-2B(OC2H5)2+ 6Zn(CH 3) 2 =2B(CH 3) 3 +6Zn< OC2H5 as a colourless spontaneously inflammable gas of unbearable smell.

The borate, Pb 2 B 6 0 1 u 4H20, is obtained as a white precipitate by adding borax to a lead salt; this on heating with strong ammonia gives PbB2044H2.

The carbonate, Cs2C03, silicofluoride, Cs2SiF6, borate, Cs20.3B 2 O 3, and the sulphides.
