mul on vaja formaldehüüdi, nii et kui keegi teab, kuidas ekstraheerida/sünteesida seda kodumaterjalidest, (me ei saa omada rahvusvahelist makseviisi, nii et ei ole ebay/amazon) ja kohalikud müüjad ei müü seda.

Mine oma kohalikku koi kalakasvatusse nad kasutavad seda kalade hooldamiseks lihtsalt ütle neile, et sul on tagahoovis tiik täis kalu.

kui te valmistate metüülamiini, siis ostke seda lihtsalt

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 ?
