Rubidium butyrate is the rubidium salt of butyric acid .

Manufacturing

Rubidium butyrate can be produced from rubidium hydroxide and butyric acid by the salt formation reaction .

${\displaystyle \mathrm {RbOH+C_{3}H_{7}COOH\longrightarrow C_{3}H_{7}COORb+H_{2}O} }$

The synthesis from rubidium carbonate and butyric acid is also possible with the development of carbon dioxide .

${\displaystyle \mathrm {Rb_{2}CO_{3}+2\ C_{3}H_{7}COOH\longrightarrow 2\ C_{3}H_{7}COORb+H_{2}O+CO_{2}\uparrow } }$

properties

Rubidium butyrate can occur in four different crystal structures . The phase transitions take place at 191  K , 346 K and 466 K.
