Barium hydroxide is an important compound of business and has ahead been produced by a
array of methods. In one known process, for example, barium carbonate is
reacted with carbon at a top temperature, as in an electric furnace, the
consistent admixed oxide getting attenuated in baptize and recrystallised. In
addition above-mentioned art process, barium carbonate or barium sulphate is
advised with silica in a rotary anhydrate at a actual top temperature to
aftermath a dibarium silicate which is again hydrolysed to aftermath a
adulterate band-aid of barium hydroxide and monobariurn silicate which have to
be recycled. These and agnate processes for the assembly of barium hydroxide
are costly, and absorb the use of top temperature and cher raw extracts as
able-bodied as boundless rccycling of intermediates.
It
is an article of the present apparatus to accommodate a rocess for accepting
barium hydroxide of top abstention from aqueous barium sulphide band-aid by an
ion barter adhesive process, and in the action to obtain, absolutely alone and
audibly from the barium hydroxide a sulphide of sodium or potassium. The
closing compounds are important in their own right.
It
is a added article of the apparatus to accommodate a connected action for
accepting barium hydroxide and sodium or potassium sulphide from hot
concentrated aqueous barium sulphide solutions.
