Nhanganyaya
Imvura isina ruvara kusvika kuchiedza yero ine kunhuhwirira kwakakosha.
2-(3-butynoxy)tetrahydrate-2H-pyran inowanzoshandiswa sepakati mune organic synthesis.
Nzira yekugadzirira 2-(3-butynoxy)tetrahydrate-2H-pyran inowanzo gadzira butynyl nekuderedza 3-butynol ne sulfuric acid, uyezve kuita ne formaldehyde kuwana 3-butynylmethanol. Chigadzirwa chacho chinoiswa esterified ne tetraoxane kuti iwane iyo yakanangwa musanganiswa.
Ruzivo rwekuchengetedza: 2-(3-butynyloxy)tetrahydrate-2H-pyran inofanirwa kudzivirira kusangana neakasimba oxidants uye yakasimba acids. Pakubata kana kushandisa komputa iyi, pfeka magirovhosi ekudzivirira uye magirazi kuti uve nechokwadi chekuti kuvhiyiwa kunoitwa munzvimbo ine mhepo yakanaka. Paunenge uchichengetedza uye kutakura, kudonha uye nzvimbo dzakasimba dzekupisa dzinofanira kudziviswa.
