Beryllium formate is a chemical compound of beryllium from the group of carboxylic acid salts . It is the beryllium salt of formic acid with the constitutional formula Be (HCOO) ₂ ..

Extraction and presentation

Beryllium formate can be produced with a salt formation reaction by dissolving beryllium hydroxide in 50% formic acid.

${\displaystyle \mathrm {Be(OH)_{2}+2HCOOH\longrightarrow Be(HCOO)_{2}+2\ H_{2}O} }$

The synthesis from beryllium oxyacetate and formic acid is also possible.

${\displaystyle \mathrm {Be_{4}O(CH_{3}COO)_{6}+8\ HCOOH\longrightarrow } }$ ${\displaystyle \mathrm {4\ Be(HCOO)_{2}+6\ CH_{3}COOH+H_{2}O} }$

The reaction of anhydrous beryllium chloride with anhydrous formic acid also leads to beryllium formate with the evolution of hydrogen chloride.

${\displaystyle \mathrm {BeCl_{2}+2\ HCOOH\longrightarrow Be(HCOO)_{2}+2\ HCl\uparrow } }$

properties

Beryllium formate occurs as an anhydrate . When slowly subliming , it reacts to form beryllium oxyformate , carbon monoxide and water.

${\displaystyle \mathrm {4\ Be(HCOO)_{2}\ {\xrightarrow {\text{500 K}}}\ Be_{4}O(HCOO)_{6}+H_{2}O+2\ CO} }$

It slowly hydrolyzes with water.
