Mawu Oyamba

Butyl acetate, yomwe imadziwikanso kuti butyl acetate, ndi madzi opanda mtundu okhala ndi fungo loyipa lomwe silisungunuka m'madzi. Zotsatirazi ndikuwulula za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha butyl acetate:

Ubwino:

- Mawonekedwe: Madzi osawoneka bwino opanda mtundu

- Mapangidwe a maselo: C6H12O2

- Kulemera kwa Maselo: 116.16

- Kachulukidwe: 0.88 g/mL pa 25 °C (lit.)

- Malo Owira: 124-126 °C (kuyatsa)

- Malo osungunuka: -78 °C (kuyatsa)

- Kusungunuka: Kusungunuka pang'ono m'madzi, kusungunuka muzosungunulira zambiri

Gwiritsani ntchito:

- Ntchito zamafakitale: Butyl acetate ndi chinthu chofunikira kwambiri chosungunulira, chomwe chimagwiritsidwa ntchito kwambiri popaka utoto, zokutira, zomatira, inki ndi mafakitale ena.

- Chemical reactions: Itha kugwiritsidwanso ntchito ngati gawo lapansi komanso zosungunulira mu kaphatikizidwe ka organic pokonzekera zinthu zina zakuthupi.

Njira:

Kukonzekera kwa butyl acetate nthawi zambiri kumapezedwa ndi esterification ya acetic acid ndi butanol, yomwe imafuna kugwiritsa ntchito zopangira asidi monga sulfuric acid kapena phosphoric acid.

Zambiri Zachitetezo:

- Pewani kutulutsa mpweya, kukhudza khungu ndi kumeza, komanso kuvala magolovesi oteteza, magalasi ndi zishango zakumaso mukamagwiritsa ntchito.

- Gwiritsani ntchito pamalo olowera mpweya wabwino ndikupewa kukhala ndi nthawi yayitali kwambiri.

- Sungani kutali ndi kuyatsa ndi ma oxidants kuti muwonetsetse kukhazikika kwawo.

Zam'mbuyo: Propyl acetate(CAS#109-60-4)

Ena: Cinnamyl acetate(CAS#103-54-8)
