Ubungcali kwimveliso yotywala bepropargyl, 1,4 butynediol kunye ne-3-chloropropyne

I-3-chloropropyne engenambala ulwelo olunokutsha olunetyhefu kakhulu oFanekishayo
  • I-3-chloropropyne engenambala ulwelo olunokutsha oluyityhefu kakhulu
  • I-3-chloropropyne engenambala ulwelo olunokutsha oluyityhefu kakhulu

I-3-chloropropyne engenambala ulwelo olunokutsha oluyityhefu kakhulu

Inkcazelo emfutshane:

I-3-chloropropyne i-organic compound kunye ne-structural formula ch ≡ cch2cl.Imbonakalo lulwelo olunokutsha olungenambala.Indawo yokunyibilika -78 ℃, iqondo lokubila ngu-57 ℃ (65 ℃), ingxinano ehambelanayo 1.0297, isalathisi se-refractive 1.4320.Indawo edanyazayo yi-32.2-35 ℃, phantse ayinyibiliki emanzini kunye neglycerol, ixubene nebenzene, carbon tetrachloride, ethanol, ethylene glycol, ether kunye ne-ethyl acetate.Ifunyenwe ngokusabela kwi-propargyl alcohol kunye ne-phosphorus trichloride.Isetyenziswa njengendawo ephakathi kwi-organic synthesis.

Ingcaciso yeMveliso

Indlela yokulungiselela: Ifunyenwe ngokusabela kwi-propargyl alcohol kunye ne-phosphorus trichloride.Okokuqala, i-oyile yomlilo kunye ne-phosphorus trichloride yongezwa kwitanki yokusabela eyomileyo, kwaye umxube we-propargyl alcohol kunye ne-pyridine yongezwa ngaphantsi kwe-20 ℃.Emva kokongeza, iyatshisa i-reflux.Emva kokusabela kwiiyure ezi-4, yongezwa emanzini omkhenkce ukwahlula umaleko wamanzi.Uluhlu lweoyile ludityaniswe ngefestile ye-sodium carbonate yamanzi kwi-ph = 5-6 ukwahlula umaleko wamanzi, kwaye emva koko ihlanjwe, yomiswe kwaye ihlanjululwe phantsi koxinzelelo oluqhelekileyo lokuqokelela amaqhezu angama-52-60 ℃ ukufumana imveliso egqityiweyo.

Ugcino:gcina kwindawo epholileyo nengena umoya.Zigcine kude nomlilo kunye nobushushu.Khusela elangeni kwaye ugcine izikhongozeli zivaliwe.Izibane ezikhusela uqhushumbo kunye neendawo zokungenisa umoya ziya kwamkelwa.Akuvumelekanga ukusebenzisa izixhobo zoomatshini kunye nezixhobo ezilula ukuvelisa iintlantsi.Indawo yokugcina iya kuxhotyiswa ngezixhobo zonyango olungxamisekileyo oluvuzayo kunye nezixhobo ezifanelekileyo zokufumana.

Injongo:Isetyenziswa ekwenzeni iyeza i-youjiangning, i-fumigant yomhlaba, njl.Ityuwa yayo ye-trisodium yeyona nto ibalaseleyo yokuqinisa ubushushu kwi-PVC, kwaye ii-esters zayo zikwayinto ebalulekileyo yokongeza kwiipolima.

Inkqubo yokuvelisa i-chlorpropargyne eyamkelwe yinkampani yethu kukuvelisa i-chlorpropargyne nge-propargyl alcohol kunye ne-thionyl chloride phantsi kwesenzo se-DMF.Le ndlela inamanyathelo alula, indlela enye yokuguqulwa kotywala be-propargyl yi-100%, kwaye i-DMF igcina ukujikeleza ngaphandle kokulahlekelwa, ngaphandle kokuxhaswa kwangaphandle, kunye nenkqubo emfutshane kunye nezixhobo ezincinci.Ngexesha elifanayo, iqonda imveliso eqhubekayo.Yinkqubo yokuqala yeekhemikhali yokuveliswa okuqhubekayo kwe-chlorpropargyne e-China

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
