Taw qhia

Dibutyl sulfide (tseem hu ua dibutyl sulfide) yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm dibutyl sulfide:

Zoo:

- Cov tsos mob: BTH feem ntau yog cov kua tsis muaj xim nrog cov ntxhiab tsw ntxhiab tsw.

- Solubility: BH yog soluble hauv cov kuab tshuaj organic xws li ethanol, ether thiab benzene, tab sis insoluble hauv dej.

- Kev ruaj ntseg: Raws li ib txwm muaj, BTH yog qhov ruaj khov, tab sis qhov tshwm sim tshwm sim los yog tawg tuaj yeem tshwm sim ntawm qhov kub thiab txias, kev kub ntxhov, lossis thaum raug oxygen.

Siv:

- Raws li cov kuab tshuaj: Dibutyl sulfide feem ntau yog siv los ua cov kuab tshuaj, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj organic synthesis.

- Kev npaj ntawm lwm cov tebchaw: BTHL tuaj yeem siv los ua qhov nruab nrab hauv kev sib txuas ntawm lwm cov organic compounds.

- Catalyst rau organic synthesis: Dibutyl sulfide kuj tseem siv tau los ua ib qho catalyst rau cov organic synthesis tshuaj.

Txoj kev:

- Txoj kev npaj dav dav: Dibutyl sulfide tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm 1,4-dibutanol thiab hydrogen sulfide.

- Kev npaj siab heev: Hauv chav kuaj, nws tseem tuaj yeem npaj los ntawm Grignard cov tshuaj tiv thaiv lossis thionyl chloride synthesis.

Cov ntaub ntawv kev nyab xeeb:

- Kev cuam tshuam rau tib neeg lub cev: BTH tuaj yeem nkag mus rau hauv lub cev los ntawm kev nqus pa thiab kev sib cuag ntawm daim tawv nqaij, uas tuaj yeem ua rau qhov muag khaus, ua pa ua pa, ua xua ntawm daim tawv nqaij, thiab kev nyuaj siab hauv nruab nrab ntawm lub paj hlwb. Kev sib cuag ncaj qha yuav tsum raug zam thiab ua kom muaj cua txaus.

- Hluav taws kub thiab tawg phom sij: BTH tej zaum yuav tshwm sim tshwm sim los yog tawg thaum kub kub, siab, los yog thaum raug oxygen. Kev saib xyuas yuav tsum tau ua kom tsis txhob muaj hluav taws xob hluav taws xob thiab hluav taws xob hluav taws xob, thiab khaws cia rau hauv lub thawv airtight.

- Toxicity: BTH yog tshuaj lom rau lub neej hauv dej thiab yuav tsum raug zam kom tso tawm rau ib puag ncig.

Yav dhau los: 2-Acetyl Thiazole (CAS # 24295-03-2)

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