Mawu Oyamba

Dibutyl sulfide (yomwe imadziwikanso kuti dibutyl sulfide) ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha dibutyl sulfide:

Ubwino:

- Maonekedwe: BTH nthawi zambiri imakhala yamadzimadzi opanda mtundu komanso fungo lapadera la thioether.

- Kusungunuka: BH imasungunuka mu zosungunulira za organic monga ethanol, ether ndi benzene, koma osasungunuka m'madzi.

- Kukhazikika: Pazikhalidwe zodziwika bwino, BTH imakhala yokhazikika, koma kuyaka kapena kuphulika kwadzidzidzi kumatha kuchitika pa kutentha kwakukulu, kupanikizika, kapena kukakhala ndi mpweya.

Gwiritsani ntchito:

- Monga zosungunulira: Dibutyl sulfide nthawi zambiri amagwiritsidwa ntchito ngati zosungunulira, makamaka muzochita za organic synthesis.

- Kukonzekera kwazinthu zina: BTHL itha kugwiritsidwa ntchito ngati gawo lapakati pakuphatikizana kwazinthu zina.

- Chothandizira kaphatikizidwe ka organic: Dibutyl sulfide itha kugwiritsidwanso ntchito ngati chothandizira pakupanga kaphatikizidwe ka organic.

Njira:

- Njira yokonzekera: Dibutyl sulfide ikhoza kukonzedwa ndi zomwe 1,4-dibutanol ndi hydrogen sulfide.

- Kukonzekera kwapamwamba: Mu labotale, itha kukonzedwanso ndi Grignard reaction kapena thionyl chloride synthesis.

Zambiri Zachitetezo:

- Zomwe zimachitika mthupi la munthu: BTH imatha kulowa m'thupi kudzera pokoka mpweya komanso kukhudzana ndi khungu, zomwe zingayambitse kupsa mtima kwa maso, kupuma movutikira, ziwengo pakhungu, komanso kupsinjika kwapakati pamitsempha. Kulumikizana mwachindunji kuyenera kupewedwa ndipo mpweya wokwanira uyenera kutsimikizika.

- Zowopsa zamoto ndi kuphulika: BTH imatha kuyatsa kapena kuphulika mwadzidzidzi pa kutentha kwambiri, kupanikizika, kapena kukakhala ndi mpweya. Chisamaliro chiyenera kutengedwa kuti musayatse ndi kutulutsa ma electrostatic, ndikusunga mu chidebe chopanda mpweya.

- Poizoni: BTH ndi poizoni ku zamoyo zam'madzi ndipo iyenera kupewedwa kuti itulutsidwe ku chilengedwe.

Zam'mbuyo: 2-Acetyl thiazole (CAS#24295-03-2)

Ena: Furfuryl methyl sulfide (CAS#1438-91-1)
