Allene, nrog rau cov tshuaj formula C3H4 thiab CAS naj npawb 463-49-0, yog cov roj tsis muaj xim nrog lub qab zib me ntsis. Nws yog insoluble hauv dej, me ntsis soluble hauv ethanol, tab sis yooj yim soluble hauv ether. Lub melting point ntawm Allene yog -136 ° C, boiling point -34 ° C, thiab qhov ceev yog 0.647 g / cm³. Nws qhov vapor ceev yog 1.42 (kwv yees rau huab cua ntawm 20 ° C), vapor siab yog 6795 mm Hg (21 ° C), thiab qhov ntsuas tsis pom kev yog 1.4169. Qhov kev pom zoo khaws cia yog nyob nruab nrab ntawm 2-8 ° C. Qhov txwv tsis pub tawg ntawm Allene yog 13%.

Nyob rau hauv cov nqe lus ntawm kev nyab xeeb, Allene yog cais raws li ib tug flammable roj thiab cov khoom phom sij daim ntawv lo yog F +, F, qhov txaus ntshai qeb code yog R12. Nws tus lej thauj khoom txaus ntshai yog UN 2200 2.1, uas yog nyob rau Chav Kawm 2.1 cov khoom txaus ntshai.

Allene yog siv los ua ib qho tseem ceeb raw cov ntaub ntawv nyob rau hauv cov organic chemistry, tshwj xeeb tshaj yog raws li ib tug intermediate hauv organic synthesis. Nws tuaj yeem npaj tau los ntawm olefins los ntawm cov tshuaj tiv thaiv tshwj xeeb, xws li ntxiv dibromocarbon rau olefins thiab tom qab ntawd siv cov hlau ua kom txo qis.

Tam sim no, muaj ntau yam purities ntawm Allene cov khoom muaj nyob rau hauv lub lag luam, xws li 95% mus rau 99.99%. Cov txheej txheem ntim khoom kuj raug kho raws li cov neeg siv khoom xav tau, suav nrog cov khoom ntim hauv lub raj mis thiab cov kaus poom uas muaj peev xwm sib txawv.

Peb pawg neeg tshawb fawb muaj ib pab pawg neeg paub txog thiab cov kws tshaj lij uas muaj kev paub dav dav thiab kev txawj ntse hauv kev lag luam ntawm cov roj tshwj xeeb thiab cov isotopes ruaj khov. Los ntawm nruam innovation thiab kev tshawb fawb thiab kev loj hlob, peb tsis tu ncua tso cov khoom zoo thiab siab dawb huv kom tau raws li cov kev xav tau ntawm peb cov neeg siv khoom.

Peb lub Hoobkas tau nruab nrog cov cuab yeej tsim khoom niaj hnub thiab cov txheej txheem tsim khoom nruj kom ntseeg tau tias muaj kev ruaj ntseg thiab kev ntseeg siab ntawm peb cov khoom. Peb tsom mus rau kev tiv thaiv ib puag ncig thiab kev tsim kho kom ruaj khov, cog lus los txo qhov cuam tshuam rau ib puag ncig thiab ua raws li cov cai thiab cov qauv tsim nyog.
