He mea motuhake ki te hanga waipiro propargyl, 1,4 butynediol me te 3-chloropropyne

3-chloropropyne kore tae tino paitini wai muramura

Whakaahuatanga Poto:

Ko te 3-chloropropyne he puhui pararopi me te tauira hanganga ch ≡ cch2cl.Ko te ahua he wai muramura kore tae.Ira whakarewa -78 ℃, ira koropupū 57 ℃ (65 ℃), kiato whanaunga 1.0297, taupū whakaata 1.4320.Ira hiko 32.2-35 ℃, tata kore e rewa i roto i te wai me te glycerol, ka uru ki te benzene, te waro tetrachloride, te waihano, te ethylene glycol, te etera me te ethyl acetate.Ka whiwhihia ma te tauhohe i te waipiro propargyl me te ūkuikui trichloride.Ka whakamahia hei takawaenga ki te whakahiato waro.

Whakaahuatanga Hua

Tikanga takahanga: Ka whiwhihia ma te tauhohe i te waipiro propargyl me te ūkuikui trichloride.Tuatahi, ka whakauruhia te hinu ahi me te ūkuikui trichloride ki roto i te tank tauhohenga maroke, ka taapirihia te ranunga o te waipiro propargyl me te pyridine ki raro i te 20 ℃.I muri i te taapiri, ka wera ki te reflux.Whai muri i te tauhohenga mo te 4 haora, ka tapirihia ki te wai hukapapa hei wehe i te paparanga wai.Ka taapirihia te paparanga hinu ki te matapihi wai konutai warowaiha ki te ph=5-6 hei wehe i te paparanga wai, katahi ka horoia, ka whakamarokehia, ka whakamarohia i raro i te pehanga noa hei kohi hautanga 52-60 ℃ kia whiwhi ai i te hua kua oti.

Rokiroki:rokiroki i roto i te whare putunga hauhautanga me te hau.Kia matara atu i te ahi me te puna wera.Tiakina mai i te ra tika, kia hiri nga ipu.Ko nga rama rama me nga whakaurunga hau ka tangohia.Karekau te whakamahi i nga taputapu miihini me nga taputapu ngawari ki te whakaputa korakora.Ko te waahi rokiroki me whakauru ki nga taputapu maimoatanga ohorere pakaru me nga taonga tango tika.

Kaupapa:Ka whakamahia i roto i te hanga rongoa youjiangning, fumigant oneone, aha atu.Ko tana tote trisodium he whakamaarama wera pai mo te PVC, a ko ona esters he taapiri nui mo nga polymers.

Ko te tukanga whakaputa chlorpropargyne i tangohia e to taatau kamupene ko te hanga o te chlorpropargyne na te waipiro propargyl me te thionyl chloride i raro i te mahi a DMF.Ko tenei tikanga he huarahi ngawari, ko te huringa kotahi-ara o te waipiro propargyl he 100%, a ko te DMF te pupuri i te tohanga kaore he mate, kaore he taapiri o waho, me te tukanga poto me te iti o nga taputapu.I te wa ano, ka mohio ki te whakaputa tonu.Koinei te tukanga matū tuatahi mo te hanga tonu o te chlorpropargyne i Haina
