Nhanganyaya

2-pentanone, inozivikanwawo sepentanone, ndeye organic compound. Iyi inotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye2-pentaone:

 

Hunhu:

- Kuonekwa: 2-pentanone imvura isina ruvara ine kunhuhwirira kwakakosha.

- Solubility: Inogona kunyungudutswa mumvura uye zvakare yakasanganiswa neakawanda organic solvents.

- Kupisa: 2-pentaone imvura inopfuta inogona kukonzera moto kana murazvo wakavhurika kana kupisa kwakanyanya.

 

Shandisa:

- Kushandiswa kwemaindasitiri: 2-pentaone inoshandiswa sechinhu chinonyungudutsa mukugadzira majasi, ingi, zvinonamira, nezvimwewo, senge diluent, yekuchenesa agent, uye reaction yepakati.

 

Nzira:

- 2-pentanone inowanzogadzirirwa ne oxidizing pentanol. Nzira yakajairika ndeyekuita nepentanol neoxidizing agent yakadai seokisijeni kana hydrogen peroxide, uye kukurumidza kuita necatalyst yakadai se potassium chromate kana cerium oxide.

 

Zvekuchengetedza

- 2-pentaone inopfuta uye inofanira kuchengetedzwa kure nemirazvo yakavhurika uye tembiricha yakakwira.

- Pfeka magirovhosi ekudzivirira, magirazi ekudzivirira, uye chekudzivirira kumeso kwenhoo kudzivirira kusangana nemeso, ganda, uye mhute.

- Tsvina inofanirwa kuraswa zvichitevedza mitemo nemirau yenzvimbo, uye haifanirwe kuraswa mumvura kana nharaunda.

- Paunenge uchichengeta uye uchishandisa, ndapota nyatsotevera akakodzera ekuchengetedza maitiro uye nhungamiro kuti uve nechokwadi chekushandisa kwayo uye kuchengetedza.
