Extractive Removal of Formaldehyde by Using an Imination Reaction with a Trident Amine Type Molecule

抄録

Extractive removal of harmful formaldehyde and ketone compounds by using an imination reaction with a trident amine derivative has been investigated. Removal of formaldehyde was quantitatively achieved over the whole pH range examined from 2 to 9 within 2 h. Although the regeneration of the compound was not adequate due to elution of the compound and incomplete reverse reaction, the removal was effective and the imination reaction took place quantitatively.
