Mawu Oyamba
Ndi madzi achikasu owala opanda mtundu ndi fungo lapadera.
2-(3-butynoxy)tetrahydrate-2H-pyran nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe ka organic.
Njira yokonzekera 2-(3-butynoxy)tetrahydrate-2H-pyran nthawi zambiri ndi kupanga butynyl mwa kuchepetsa 3-butynol ndi sulfuric acid, ndikuchita ndi formaldehyde kupeza 3-butynylmethanol. Mankhwalawa amapangidwa ndi esterified ndi tetraoxane kuti apeze zomwe akufuna.
Zambiri zachitetezo: 2-(3-butynyloxy)tetrahydrate-2H-pyran iyenera kupewa kukhudzana ndi ma okosijeni amphamvu ndi ma acid amphamvu. Mukamagwira kapena kugwiritsa ntchito mankhwalawa, valani magolovesi oteteza ndi magalasi kuti muwonetsetse kuti ntchitoyi ikuchitika pamalo abwino mpweya wabwino. Posungira ndi kunyamula, kugwa ndi magwero amphamvu otentha ayenera kupewedwa.
