Isingeniso
Iwuketshezi oluphuzi olukhanyayo olungenambala olunephunga elikhethekile.
I-2-(3-butynoxy)tetrahydrate-2H-pyran ivamise ukusetshenziswa njengendawo emaphakathi ku-organic synthesis.
Indlela yokulungisa i-2-(3-butynoxy)tetrahydrate-2H-pyran ngokuvamile iwukwenza i-butynyl ngokunciphisa i-3-butynol nge-sulfuric acid, bese isabela nge-formaldehyde ukuze kutholwe i-3-butynylmethanol. Umkhiqizo ufakwa esterified nge-tetraoxane ukuze uthole inhlanganisela ehlosiwe.
Ulwazi lokuphepha: 2-(3-butynyloxy)tetrahydrate-2H-pyran kufanele igweme ukuthintana nama-oxidants aqinile nama-asidi aqinile. Lapho uphatha noma usebenzisa lesi sithako, gqoka amagilavu okuzivikela kanye nezibuko ukuze uqinisekise ukuthi umsebenzi wenziwa endaweni enomoya omuhle. Lapho ugcina futhi uthutha, ukuwa kanye nemithombo yokushisa enamandla kufanele kugwenywe.
