Tshwj xeeb hauv kev tsim cov cawv propargyl, 1,4 butynediol thiab 3-chloropropyne
Ua kua nrog volatile thiab pungent tsw.Nws yog miscible nrog dej, ethanol, aldehydes, benzene, pyridine, chloroform thiab lwm yam organic solvents, ib nrab soluble hauv carbon tetrachloride, tab sis insoluble nyob rau hauv aliphatic hydrocarbons.Nws yog ib qho yooj yim tig daj thaum nws muab tso rau ntev, tshwj xeeb tshaj yog thaum nws ntsib teeb.Nws tuaj yeem tsim azeotrope nrog dej, qhov taw tes azeotropic yog 97 ℃, thiab cov ntsiab lus ntawm propargyl cawv yog 21 2%.Nws cov vapor thiab huab cua tsim ib qho kev sib xyaw tawg, uas tuaj yeem ua rau combustion thiab tawg thaum qhib hluav taws thiab kub kub.Nws tuaj yeem cuam tshuam nrog oxidants.Nyob rau hauv cov ntaub ntawv ntawm kub kub, polymerization cov tshuaj tiv thaiv yuav tshwm sim thiab ib tug loj tus naj npawb ntawm exothermic phenomena yuav tshwm sim, ua rau lub thawv tawg thiab tawg xwm txheej.

Propargyl cawv yog siv dav hauv tsev kho mob (sulfonamides, fosfomycin sodium, thiab lwm yam) thiab tsim cov tshuaj tua kab (propargyl mite).Nws tuaj yeem ua rau corrosion inhibitors rau cov kav dej tho thiab cov kav dej hauv cov roj av.Nws tuaj yeem siv los ua ib qho ntxiv hauv kev lag luam steel los tiv thaiv hydrogen embrittlement ntawm steel.Nws tuaj yeem ua rau ci ci hauv kev lag luam electroplating.
Propargyl cawv yog cov khoom siv tshuaj lom neeg uas muaj tshuaj lom: ld5020mg / kg (kev tswj qhov ncauj rau nas);16mg / kg (liab percutaneous);Lc502000mg / m32 teev (tsim nyob rau hauv nas);Cov nas nqus tau 2mg / l × 2 teev, tuag taus.
Subacute thiab mob toxicity: nas nqus tau 80ppm × 7 teev / hnub × 5 hnub / lub lis piam × Hnub 89, lub siab thiab lub raum o thiab lub hlwb degenerated.
