Nhanganyaya

5-Methylfurfural, inozivikanwawo se5-methyl-2-oxocyclopenten-1-aldehyde kana 3-methyl-4-oxoamyl acetate. Iyi inotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye5-methylfurfural:

 

Hunhu:

Kuonekwa: 5-Methylfurfural imvura isina ruvara ine kunhuhwirira kwakakosha.

Density: approx. 0.94 g/mL.

Solubility: Inogona kunyungudutswa mumvura, madoro uye ether solvents.

 

Shandisa:

Kemikari synthesis yepakati: Inogona zvakare kushandiswa mukugadzirwa kwemamwe organic komisheni uye seyakagadzirwa precursor yehydroquinone.

 

Nzira:

Nzira yakajairwa yekugadzira iri kuburikidza necatalytic reaction yeBacillus isosparatus-inoenderana enzymes. Kunyanya, 5-methylfurfural inogona kuwanikwa nekunetseka kuvirisa kwebutyl acetate.

 

Zvekuchengetedza

5-Methylfurfural inogumbura ganda nemeso, saka iwe unofanirwa kuterera kuchengetedza maoko ako nemeso uye kudzivirira kubata panguva yekushandiswa.

Inhalation ye5-methylfurfural inhalation inogona kukonzera zviratidzo zvisingafadzi zvakadai sedzungu uye kurara, saka iva nechokwadi chokuti inoshandiswa munzvimbo ine mhepo yakanaka uye kudzivirira kuratidzwa kwenguva refu kune yakakwirira yehuputi.

Paunenge uchichengeta uye uchibata 5-methylfurfural, kutarisirwa kunofanira kutorwa kudzivirira kubata neoxidant kudzivirira moto kana kuputika. Ita shuwa kuti mudziyo wekuchengetera wakanyatsovharwa uye wakachengetwa munzvimbo inotonhorera, yakaoma uye ine mhepo, kure nemoto.
