Abstract

Sodium formate is produced by introducing carbon monoxide into water containing sodium sulphate and lime, the sodium sulphate being maintained at a concentration not greater than 7 per cent calculated as Na2SO4. This concentration may be regulated by the presence of basic sodium calcium sulphate, Na4Ca3(SO4)4 (OH)2, obtained by heating calcium or sodium hydroxide in water with sodium sulphate and calcium sulphate, or with substances containing or forming these compounds, e.g. calcium sodium sulphate, or sodium chloride and calcium sulphate. Another method of maintaining the sodium sulphate concentration consists in adding sodium sulphate or calcium sodium sulphate or basic sodium calcium sulphate to replace the sulphate as it is consumed, excess of lime being either present in the reaction vessel or gradually added thereto. Specification 7875/04 is referred to.ALSO:Basic sodium calcium sulphate, Na4 Ca3 (SO4)4 (OH)23 is produced by heating calcium or sodium hydroxide in water with sodium sulphate and calcium sulphate, or with substances containing or forming these compounds, e.g. calcium sodium sulphate, or sodium chloride and calcium sulphate.
