man reikia formaldehido, todėl jei kas nors žino, kaip jį išgauti / sintetinti iš buitinių medžiagų, (mes negalime turėti tarptautinio mokėjimo metodo, todėl ne ebay / azon), o vietiniai pardavėjai jo neparduoda.

Nueikite į vietinę koi žuvininkystę, jie jį naudoja žuvų priežiūrai, tik pasakykite jiems, kad turite kiemo tvenkinį, pilną žuvų.

jei gaminate metilaminą, tiesiog nusipirkite jo iš

Im also looking for a diy way to get formaldehyde..Anyone know if this setup would work: fill a 2 neck flask with copper wool, equip other neck with drip funnel for dispensing methanol into the flask, other neck is equipped with a tube going to a water bottle for condensing the formaldehyde...flask is heated to something like 350 deg celsius and methanol is dripped in in a controlled flow.. formaldehyde gas is formed and directed to water ?
