Intshayelelo
Lulwelo olungenambala ukuya kokukhanya olutyheli olunevumba elikhethekileyo.
I-2-(3-butynoxy) i-tetrahydrate-2H-pyran isoloko isetyenziswa njengendawo ephakathi kwi-organic synthesis.
Indlela yokulungiselela i-2-(3-butynoxy) i-tetrahydrate-2H-pyran ngokuqhelekileyo idibanisa i-butynyl ngokunciphisa i-3-butynol nge-asidi ye-sulfuric, kwaye emva koko iphendule nge-formaldehyde ukufumana i-3-butynylmethanol. Imveliso i-esterified kunye ne-tetraoxane ukufumana ikhompawundi ekujoliswe kuyo.
Ulwazi ngokhuseleko: I-2-(3-butynyloxy)tetrahydrate-2H-pyran kufuneka inqande ukudibana nee-oxidants ezinamandla kunye neeasidi ezinamandla. Xa uphatha okanye usebenzisa le khompawundi, nxiba iiglavu ezikhuselayo kunye nezibuko ukuqinisekisa ukuba umsebenzi wenziwa kwindawo enomoya omhle. Xa ugcina kwaye uhambisa, ukuwa kunye nemithombo yokushisa enamandla kufuneka igwenywe.
