Purification and recovery of hydrocyanic acid
Thread Content
Hydrocyanic acid is an important raw material in chemical manufacturing. However, it is volatile and toxic, and its solubility is particularly good. Therefore, when hydrogen cyanide is used as the reactant and a small amount of unreacted hydrogen cyanide remains after the reaction, can it be completely recovered using ordinary distillation? Since hydrogen cyanide is dangerous even in small quantities, it is necessary to recover it all – what method should be used?
