Ikhemikhali yelabhoratri enetyhefu kakhulu - utywala obunxilisayo obonakalisiweyo

Ikhemikhali yelabhoratri enetyhefu kakhulu - ipropargyl alcohol

Inkcazelo emfutshane:

I-Propargyl Utywala, i-molecular formula C3H4O, ubunzima be-molecular 56. Ulwelo olungenambala olungenambala, oluguquguqukayo kunye nevumba elibi, ityhefu, ukucaphuka okukhulu kwesikhumba kunye namehlo.Indawo ephakathi kwi-organic synthesis.Ikakhulu isetyenziselwa ukuhlanganiswa kwe-antibacterial kunye ne-anti-inflammatory drugs sulfadiazine;Emva kwe-hydrogenation inxalenye, i-propylene alcohol inokuvelisa i-resin, kwaye emva kwe-hydrogenation epheleleyo, i-n-propanol ingasetyenziselwa njengento eluhlaza ye-anti-tuberculosis drug ethambutol, kunye nezinye iikhemikhali kunye neemveliso zamachiza.Iyakwazi ukuthintela iasidi kwi-iron, ikopolo kunye nenikeli kunye nezinye isinyithi, ezisetyenziswa njenge-rust remover.Isetyenziswa ngokubanzi ekutsalweni kweoli.Isenokusetyenziswa njenge-solvent, i-stabilizer ye-chlorinated hydrocarbons, i-herbicide kunye ne-insecticide.Ingasetyenziselwa ukuveliswa kwe-acrylic acid, i-acrolein, i-2-aminopyrimidine, i-γ-picauline, i-vitamin A, i-stabilizer, i-corrosion inhibitor kunye nokunye.

Amanye amagama: i-propargyl alcohol, i-2-propargyl - i-1-alcohol, i-2-propargyl alcohol, i-propargyl alcohol acetylene methanol.

Intshayelelo

Idatha ye-Toxicological
Ubuthi obunobungozi: ngomlomo LD50: 70mg / kg kwiigundane;
Umvundla nge-percutaneous LD50: 16mg/kg;
Iimpuku ziphefumle i-LD50: 2000mg/m3/2h.

Idatha yendalo
Inetyhefu kwizinto eziphila emanzini.Inokubangela iziphumo ezibi kwimekobume yamanzi.
Inetyhefu.Ulusu olubi kunye nokucaphuka kwamehlo.

Iipropati kunye nozinzo
Kuphephe ubushushu.Kuphephe ukudibana ne-oxidant eyomeleleyo, i-asidi eyomeleleyo, isiseko esomeleleyo, i-acyl chloride, i-anhydride.
Inetyhefu.Inokucaphukisa kakhulu ulusu kunye namehlo.Kucetyiswa ukuba unxibe iiglasi zokukhusela kunye neiglavu ngexesha lokusebenza.

Indlela yokugcina

Gcina kwindawo epholileyo nengena umoya.Zigcine kude nomlilo kunye nobushushu.Ubushushu akufunekanga budlule kwi-30℃.Gcina isikhongozeli singangeni moya.Kufuneka igcinwe ngokwahlukileyo kwi-oxidants, i-acids, i-alkali kunye neekhemikhali ezidliwayo, kwaye akufanele ixutywe.Musa ukugcina izinto ezininzi okanye ixesha elide.Izibane ezikhusela uqhushumbo kunye nezixhobo zokungenisa umoya ziyamkelwa.Musa ukusebenzisa izixhobo zoomatshini kunye nezixhobo ezithanda ukuba yintlantsi.Indawo yokugcina iya kuxhotyiswa ngezixhobo zonyango olungxamisekileyo oluvuzayo kunye nezixhobo ezifanelekileyo zokubamba.Inkqubo yokulawula "isihlanu-kabini" kwizinto eziyityhefu kakhulu kufuneka iphunyezwe ngokungqongqo.

Ngenxa yokuba i-proPARgyl alcohol ine-flash point ephantsi kwaye inokusabela ngamandla xa kukho ukungcola, ingqalelo ekhethekileyo kufuneka ihlawulwe kukhuseleko.Ukugcinwa kwexesha elifutshane kunye nokuthutha, kufumaneka kwizikhongozeli zentsimbi ezicocekileyo ezingena mhlwa.Ukugcinwa kwexesha elide, izitya ezifakwe ngensimbi engenasici, iglasi okanye i-phenolic resin kufuneka zisetyenziswe, kunye nezinto ezifana ne-aluminium kufuneka zigwenywe.Gcina kwaye uhambise ngokwemigaqo yeekhemikhali ezinokutsha.

Sebenzisa

Isetyenziswe njenge-rust remover, i-chemical intermediate, i-corrosion inhibitor, i-solvent, i-stabilizer, njl.

Ingasetyenziswa njenge-hydrochloric acid kunye nezinye i-industrial pickling corrosion inhibitor kwi-acidizing fracturing process of oil and gas Wells.Ingasetyenziswa njenge-corrosion inhibitor yodwa, kungcono ukuba nefuthe le-synergistic kunye nezinto eziphathekayo, ukuze kufumaneke ukusebenza kakuhle kwe-corrosion inhibition.Umzekelo, ukuze kwandiswe inhibition umhlwa utywala alkyyl kwi dilute sulfuric acid isisombululo, sodium chloride, potassium chloride, calcium chloride, bromide potassium, iodide potassium okanye chloride zinki kunye nezinye ukusetyenziswa ezintsonkothileyo.

Ingasetyenziswa njenge-corrosion inhibitor yodwa, kungcono ukuba nefuthe le-synergistic kunye nezinto eziphathekayo, ukuze kufumaneke ukuphumelela okuphezulu kwe-corrosion inhibition.Ngokomzekelo, ukuze kwandiswe impembelelo yokuthintela ukubola kwe-alkyyl yotywala kwisisombululo se-sulfuric acid, kuyacetyiswa ukuba ungeze i-sodium chloride, i-potassium chloride, i-calcium chloride, i-potassium bromide, i-iodide ye-potassium okanye i-zinc chloride.

Ngaphambili: Ukusetyenziswa kwe-butanediol kwizinto zokuthambisa

Okulandelayo: I-Propargyl iya kupholisa kwaye iqhume
