Product Description

Kugadzirira nzira: Inowanikwa nekuita propargyl doro ne phosphorus trichloride.Kutanga, mafuta emoto uye phosphorus trichloride inowedzerwa muakaoma reaction tank, uye musanganiswa wepropargyl doro uye pyridine inowedzerwa inodonha pazasi 20 ℃.Mushure mekuwedzera, inopisa kuti iite reflux.Mushure mekuita kwemaawa mana, inowedzerwa mumvura yechando kuti iparadzanise denga remvura.Iyo mafuta layer inowedzerwa ne sodium carbonate mvura hwindo kune ph = 5-6 kuti iparadzanise dhizaini yemvura, yobva yashambidzwa, yakaomeswa uye yakanyungudutswa pasi pekumanikidzwa kwakajairwa kuunganidza 52-60 ℃ zvikamu kuti uwane chigadzirwa chakapedzwa.

Kuchengeta:chengetera muimba inotonhorera inofefetera uye inofefetera.Ramba kure nemoto nekupisa.Dzivirira kubva kuzuva rakananga uye chengeta midziyo yakavharwa.Kuputika kwemwenje wemwenje uye mhepo yekufefetera ichagamuchirwa.Zvinorambidzwa kushandisa michina michina uye maturusi ari nyore kugadzira sparks.Nzvimbo yekuchengetera ichave yakashongedzerwa neyakavuza yekurapa yekukurumidzira michina uye yakakodzera yekugamuchira zvinhu.

Chinangwa:Inoshandiswa mukugadzira mushonga youjiangning, ivhu fumigant, etc. Iyo zvakare inogadzirisa einjiniya mapurasitiki.Itrisodium munyu yaro yakanakisa kupisa inodzikamisa yePVC, uye esters ayo akakosha ekuwedzera kune mapolymer.

Iyo chlorpropargyne yekugadzira maitiro yakagamuchirwa nekambani yedu kugadzirwa kwechlorpropargyne nepropargyl doro uye thionyl chloride pasi pechiito cheDMF.Iyi nzira ine matanho akareruka, nzira imwe chete yekushandura doro repropargyl ndeye 100%, uye DMF inochengetedza kutenderera pasina kurasikirwa, pasina kuwedzera kwekunze, nemaitiro mafupi uye zvishoma zvishandiso.Panguva imwecheteyo, inoona kugadzirwa kunoramba kuripo.Ndiyo yekutanga makemikari maitiro ekuenderera mberi kugadzirwa kwechlorpropargyne muChina
