Boleng:

- E na le ponahalo e se nang mmala mme e na le tatso e monate e ikgethang.

- Furfural e na le ho qhibiliha ha tlase metsing, empa e qhibiliha ka har'a joala le lihlapolli tsa ether.

- Furfural e na le oxidized habonolo mme e senyeha habonolo ke mocheso.

Mokhoa:

- Mokhoa o tloaelehileng oa ho lokisa furfural o fumanoa ka oxidation ea C6 alkyl ketones (mohlala, hexanone).

- Mohlala, hexanone e ka etsoa oxidized ho furfural ka ho sebelisa oksijene le li-catalyst tse kang potassium permanganate kapa hydrogen peroxide.

- Ho phaella moo, acetic acid e ka boela ea itšoara ka mefuta e sa tšoaneng ea joala ea C3-C5 (joaloka joala ea isoamyl, joalo-joalo) ho theha ester e lumellanang, ebe e fokotsoa ho fumana furfural.
