3-chloropropyne zopanda mtundu zamadzimadzi zomwe zimatha kuyaka

Njira yokonzekera: Amapezeka pochita mowa wa propargyl ndi phosphorous trichloride.Choyamba, mafuta amoto ndi phosphorous trichloride amawonjezedwa mu thanki youma, ndipo kusakaniza kwa mowa wa propargyl ndi pyridine kumawonjezedwa pansi pa 20 ℃.Pambuyo powonjezera, imatenthedwa kuti iwonongeke.Pambuyo pakuchita kwa maola 4, amawonjezeredwa m'madzi oundana kuti alekanitse madziwo.Mafuta osanjikiza amawonjezedwa ndi zenera lamadzi la sodium carbonate kuti ph = 5-6 kuti alekanitse gawo lamadzi, kenako kutsukidwa, zouma ndi kusungunulidwa pansi pamavuto abwinobwino kuti asonkhanitse tizigawo ta 52-60 ℃ kuti mupeze chomaliza.

Posungira:sungani m'nyumba yosungiramo zozizira komanso yolowera mpweya wabwino.Khalani kutali ndi moto ndi gwero la kutentha.Tetezani ku dzuwa lachindunji ndipo sungani zotengera zotsekedwa.Zowunikira zotsimikizira kuphulika ndi malo olowera mpweya wabwino ziyenera kulandiridwa.Ndizoletsedwa kugwiritsa ntchito zida zamakina ndi zida zomwe zimakhala zosavuta kutulutsa zopsereza.Malo osungiramo zinthu adzakhala ndi zida zowonongeka zowonongeka ndi zipangizo zoyenera kulandira.

Cholinga:Amagwiritsidwa ntchito popanga mankhwala youjiangning, fumigant m'nthaka, ndi zina zambiri. Ndiwosinthiranso mapulasitiki a engineering.Mchere wake wa trisodium ndiwothandiza kwambiri kutentha kwa PVC, ndipo ma esters ake ndiwowonjezeranso zofunika pa ma polima.

Njira yopanga chlorpropargyne yotengedwa ndi kampani yathu ndikupanga chlorpropargyne ndi mowa wa propargyl ndi thionyl chloride mothandizidwa ndi DMF.Njirayi ili ndi masitepe osavuta, njira imodzi yosinthira mowa wa propargyl ndi 100%, ndipo DMF imasunga kufalikira popanda kutayika, popanda zowonjezera zakunja, ndi ndondomeko yochepa komanso zipangizo zochepa.Panthawi imodzimodziyo, imazindikira kupanga kosalekeza.Ndi njira yoyamba yamankhwala yopanga mosalekeza ya chlorpropargyne ku China
