Iimveliso
Ubungcali kwimveliso yotywala bepropargyl, 1,4 butynediol kunye ne-3-chloropropyne
Ulwelo olunetyhefu ephezulu lugqwesileyo kwimveliso yotywala bepropargyl
Ingcaciso yeMveliso
Ulwelo olunevumba eliguquguqukayo nelinukayo.Ixubene namanzi, i-ethanol, i-aldehydes, i-benzene, i-pyridine, i-chloroform kunye nezinye izinyibilikisi zendalo, zinyibilika ngokuyinxenye kwi-carbon tetrachloride, kodwa ayinyibiliki kwi-aliphatic hydrocarbons.Kulula ukujika tyheli xa ibekwe ixesha elide, ngakumbi xa idibana nokukhanya.Iyakwazi ukwenza i-azeotrope ngamanzi, i-azeotropic point yi-97 ℃, kwaye umxholo we-propargyl alcohol yi-21 2%. Ingenza i-azeotrope ngebenzene, i-azeotropic point yi-73 ℃, kwaye umxholo we-propargyl alcohol yi-13.8%.Umphunga wayo kunye nomoya zenza umxube oqhumayo, onokubangela ukutsha kunye nokudubula kwimeko yomlilo ovulekileyo kunye nobushushu obuphezulu.Inokusabela ngamandla kunye nee-oxidants.Kwimeko yobushushu obuphezulu, i-polymerization reaction inokuthi yenzeke kwaye inani elikhulu lezinto eziphazamisayo zinokuthi zenzeke, ezikhokelela ekuqhekekeni kwesikhongozeli kunye neengozi zokudubula.

I-propargyl alcohol isetyenziswa kakhulu kwizibhedlele (sulfonamides, fosfomycin sodium, njl.) kunye nokuveliswa kwee-pesticides (propargyl mite).Ingenziwa kwi-corrosion inhibitors kwimibhobho yokubhobhoza kunye nemibhobho yeoli kwishishini lepetroleum.Ingasetyenziselwa njengesongezo kwishishini lensimbi ukukhusela i-hydrogen embrittlement yentsimbi.Ingenziwa ibe yizikhanyisi kwishishini le-electroplating.
I-propargyl alcohol yimveliso yeekhemikhali ehlelwe kakhulu enetyhefu ebukhali: ld5020mg/kg (ulawulo lomlomo kwiimpuku);16mg/kg (umvundla percutaneous);Lc502000mg/m32 iiyure (ukuphefumla kwiimpuku);Iigundane ziphefumle i-2mg / l × iiyure ze-2, ezibulalayo.
I-Subacute kunye ne-toxicity engapheliyo: iigundane ziphefumle i-80ppm × iiyure ze-7 / usuku × iintsuku ezi-5 / ngeveki × Ngomhla we-89, isibindi kunye nezintso zidumbile kwaye iiseli ziyancipha.
