Imikhiqizo
Isebenza ngokukhethekile ekukhiqizeni utshwala be-propargyl, i-1,4 butynediol kanye ne-3-chloropropyne
Uketshezi olunobuthi obuphezulu bomkhiqizo we-propargyl alcoho
Incazelo Yomkhiqizo
Uketshezi olunephunga elishisayo nelinukayo.Ixubene namanzi, i-ethanol, i-aldehydes, i-benzene, i-pyridine, i-chloroform nezinye izincibilikisi eziphilayo, inyibilika kancane ku-carbon tetrachloride, kodwa ayincibiliki kuma-aliphatic hydrocarbon.Kulula ukuphenduka kubephuzi uma ibekwe isikhathi eside, ikakhulukazi uma ihlangana nokukhanya.Ingenza i-azeotrope ngamanzi, i-azeotropic point ingu-97 ℃, kanti okuqukethwe kwe-propargyl alcohol ingu-21 2%. Ingenza i-azeotrope nge-benzene, iphoyinti le-azeotropic ngu-73 ℃, kanti okuqukethwe kwe-propargyl alcohol kungu-13.8%.Umhwamuko wawo kanye nomoya kwakha ingxube eqhumayo, engabangela ukuvutha nokuqhuma uma kuba nomlilo ovulekile nokushisa okuphezulu.Ingasabela ngokuqinile nama-oxidants.Esimeni sokushisa okuphezulu, ukusabela kwe-polymerization kungase kwenzeke futhi inani elikhulu lezimo ze-exothermic lingenzeka, okuholela ekuqhekekeni kwesitsha kanye nezingozi zokuqhuma.

I-propargyl alcohol isetshenziswa kabanzi ezibhedlela (i-sulfonamides, i-fosfomycin sodium, njll.) kanye nokukhiqizwa kwezibulala-zinambuzane (i-propargyl mite).Ingenziwa ibe ama-corrosion inhibitors amapayipi okubhola namapayipi kawoyela embonini ye-petroleum.Ingasetshenziswa njengesengezo embonini yensimbi ukuvimbela i-hydrogen embrittlement yensimbi.Ingenziwa ibe yizikhanyisi embonini ye-electroplating.
I-Propargyl alcohol iwumkhiqizo wamakhemikhali ohlukaniswe kakhulu onobuthi obunzima: ld5020mg/kg (ukuphathwa ngomlomo kumagundane);16mg/kg (unogwaja percutaneous);Lc502000mg/m32 amahora (ukuphefumula emagundeni);Amagundane ahogele i-2mg/l × amahora ama-2, abulalayo.
Ubuthi obuncane nobungamahlalakhona: amagundane ahogele i-80ppm × amahora angu-7 / usuku × izinsuku ezingu-5 / isonto × Ngosuku lwama-89, isibindi nezinso zavuvukala futhi amangqamuzana ayancipha.
