Taw qhia

1-Bromo-2-butyne yog ib qho organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:

 

Cov Khoom Siv: 1-Bromo-2-butyne yog cov kua tsis muaj xim rau daj ntseg daj nrog cov ntxhiab tsw txawv. Nws yog insoluble hauv dej tab sis tuaj yeem soluble hauv cov kuab tshuaj organic xws li ethers thiab cawv. Nws muaj ib tug tsawg ignition point thiab yog nquag combustion.

 

Kev Siv: 1-Bromo-2-butyne feem ntau yog siv los ua cov tshuaj reagent hauv cov organic synthesis cov tshuaj tiv thaiv. Nws tuaj yeem siv rau hauv kev sib txuas ntawm ntau cov organic tebchaw xws li alkynes, haloalkynes, thiab organometallic compounds. Nws kuj tseem siv tau los ua cov kuab tshuaj organic thiab polymer additive.

 

Txoj kev npaj: Kev npaj ntawm 1-bromo-2-butyne yog tsuas yog tau los ntawm bromide 2-butyne. Bromine yog thawj zaug ntxiv rau cov kuab tshuaj ethanol, ua raws li cov tshuaj alkaline rau catalyze cov tshuaj tiv thaiv. Thaum qhov kub thiab txias thiab lub sijhawm tshuaj tiv thaiv, 1-bromo-2-butyne yog tsim.

 

Cov ntaub ntawv kev nyab xeeb: 1-Bromo-2-butyne yog ib qho chaw txaus ntshai thiab yuav tsum tau saib xyuas. Nws yog irritating thiab lom thiab tuaj yeem ua rau lub qhov muag thiab tawv nqaij puas. Thaum siv, cov hnab looj tes tiv thaiv, tsom iav thiab cov khaub ncaws tiv thaiv yuav tsum hnav. Ua haujlwm nyob rau hauv ib qho chaw zoo-ventilated thiab tsis txhob nqus pa. Nyob rau hauv cov ntaub ntawv ntawm kev huam yuaj los yog inhalation, kev pab kho mob yuav tsum tau nrhiav tam sim ntawd.
