Nhanganyaya

Furfural, inozivikanwawo se2-hydroxyunsaturated ketone kana 2-hydroxypentanone. Inotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza furfural:

Hunhu:

- Iyo ine chitarisiko chisina ruvara uye ine yakakosha inonaka inonaka.

- Furfural ine yakaderera solubility mumvura, asi inonyungudika mudoro uye ether solvents.

- Furfural iri nyore oxidized uye nyore kuora nekupisa.

Nzira:

- Nzira yakajairika yekugadzirira furfural inowanikwa neoxidation yeC6 alkyl ketones (semuenzaniso, hexanone).

- Semuyenzaniso, hexanone inogona oxidized kuti furfural uchishandisa oxygen uye catalysts akadai potassium permanganate kana hydrogen peroxide.

- Mukuwedzera, acetic acid inogonawo kugadziriswa nemhando dzakasiyana-siyana dzeC3-C5 (zvakadai se isoamyl doro, nezvimwewo) kuti iite ester inoenderana, uye yozoderedzwa kuti iwane furfural.

Zvekuchengetedza

- Furfural ine yakaderera toxicity asi ichiri kuda kushandiswa uye kuchengetwa nehanya.

- Dzivisa kusangana neganda nemaziso, uye sukurudza nekukurumidza nemvura yakawanda kana zvikadaro.

- Kuchengetedza kunofanira kutorwa kuti usasangana neakasimba oxidants, zvitubu zvinopisa, nezvimwewo panguva yekuchengetedza uye kushandiswa kudzivirira moto kana kuputika.

- Mamiriro akanaka ekufemesa anofanirwa kupihwa panguva yekushandiswa kudzivirira inhalation ye furfural vapors.

Zvakapfuura: 2-Isobutyl-3-Methyl Pyrazine (CAS#13925-06-9)

Zvinotevera: 4-Methyltetrahydrothiophen-3-One (CAS#50565-25-8)
