Kev tsis

1-Butene

product-585-380

n-Butylenefeem ntau hais txog1-butene(cov tshuaj formula C₄H₈), uas yog ib qho ntawm plaub isomers ntawm butene. Nws yog ib qho tseem ceeb heev cov khoom siv tshuaj lom neeg hauv kev lag luam.

Hauv qab no yog kev sib cais ntawm nws cov ntaub ntawv tseem ceeb los ntawm ntau yam:

🧪 Cov Ntaub Ntawv Tseem Ceeb

Tus kheej: Ntawm plaub butene isomers, 1-butene yog scientifically hu uan-butylene, kuj hu ua-butylene.

Lub cev lub xeev: Nws yog cov roj tsis muaj xim ntawm chav tsev kub thiab siab, nrog cov ntxhiab tsw ntxhiab tsw.

Basic Physical Properties: Nws qhov kub kub yog qhov tsawg heev (kwv yees . -6.3℃). Nws yog insoluble hauv dej tab sis yooj yim soluble hauv cawv, ethers, thiab lwm yam organic solvents. Nws yog cov nplaim hluav taws kub heev thiab tuaj yeem tsim cov khoom tawg nrog huab cua (hloov txwv: 1.6% -10%).

⚙️ Kev siv tseem ceeb

Tus nqi ntawm n-butylene feem ntau yog nyob rau hauv nws cov tshuaj siv tshuaj. Nws ua haujlwm raws li qhov txuas tseem ceeb ntawm kev lag luam petrochemical thiab ntau yam khoom lag luam hauv qab.

Raws li ib tug Comonomer: Nws yog ib qho tseem ceeb comonomer nyob rau hauv zus tau tej covLinear Tsawg-Density Polyethylene(LLDPE), qhov uas nws pab kho cov khoom siv ntawm cov khoom yas kawg los ntawm copolymerization.

Synthesis ntawm Lwm Cov Tshuaj: Nws yog cov khoom siv raw rau kev sib txuassec-butyl cawvthiabbutadiene(ib qho tseem ceeb monomer rau hluavtaws roj hmab). Tsis tas li ntawd, los ntawm isomerization, n-butylene tuaj yeem hloov mus rau qhov muaj nqis duaisobutylene, uas yog siv los tsim cov roj hmab butyl, MTBE (methyl tert-butyl ether), thiab lwm yam khoom.

🏭 Kev tsim khoom thiab kev nyab xeeb

Qhov Chaw Tseem Ceeb: Industrially, nws yog feem ntau tau los ntawm kev sib cais C4 feem, ib tug byproduct los ntawm roj av catalytic cracking los yog ethylene cracking units. Txij li thaum cov ntsiab lus kub ntawm 1-butene thiab isobutylene yog qhov ze heev (qhov txawv ntawm tsuas yog 0.6 degree), kev sib cais thiab kev ua kom huv yog qhov nyuaj heev.

Kev Nyab Xeeb Kev Nyab Xeeb: Raws li cov roj hluav taws kub heev, nws yuav tsum tau khaws cia thiab thauj mus deb ntawm qhov chaw ntawm qhov hluav taws kub thiab cua sov. Nws muaj cov nyhuv narcotic thiab asphyxiating; nqus tau cov concentration siab yuav ua rau muaj kev phom sij rau kev noj qab haus huv. Yog li ntawd, qhov cua txaus yog qhov tseem ceeb thaum tuav haujlwm.
