The basic information Pseudonym cesiumFormatemonoTEL; Cesiumformatehydrate; formic acid, cesium salt (1:1); caesium formate Molecular formula CHCSO2 The molecular weight of 177.92 Introduction Cesium formate is an organic compound whose chemical formula is HCOOCs. It is a white powder that can easily dissolves in water, and its solution is alkaline. Cesium formate exists in monohydrate and anhydrous substance. Physical properties Cesium formate is easy to be deliquesced. Its aqueous solution is colorless and transparent, and its concentrated solution is with high density, up to 2.2g/cm. Chemical properties When heated, cesium monohydrate underwent phase change at 36 ~ 46℃, and was dehydrated at 90 ~ 260℃ to obtain anhydrous matter. About 263℃ began to melt and gradually decomposed, produced cesium carbonate, cesium oxalate, carbon monoxide, hydrogen and other substances, at 600℃ completely decomposed, the product is cesium carbonate. However, cesium formate decomposed at 260 ~ 500℃ and produced cesium carbonate. use Cesium formate can be used as drilling fluid for petroleum exploration.
