Kugwiritsa ntchito

Burgess dehydrating agent, yomwe imatchedwanso Burgess reagent, ndi methyl N-(triethylaminosulfuryl) carbamate.Itha kukhala yopanda madzi m'thupi pansi pazikhalidwe zofatsa ndipo ndi njira yochepetsera madzi m'thupi.Amagwiritsidwa ntchito kutembenuza ma alcohols achiwiri ndi apamwamba okhala ndi ma protoni oyandikana nawo kukhala alkenes.

Ikhoza kukonzedwa ndi zomwe chlorosulfone isocyanate ndi triethylamine mu methanol.Pa kutaya madzi m'thupi, sulfure amawukiridwa ndi gulu la hydroxyl, kenako kuchotsedwa kwa cis kumachitika.Burgess dehydrating agents amathanso kugwiritsidwa ntchito kupanga mankhwala a isonitrile kuchokera ku formamide.Zomwe zimapangidwira zimakhala zofanana ndi momwe xanthate kuchotsa, ndipo alkene imapezedwanso ndi cis kuthetsa kusintha kwa mphete ya mamembala asanu ndi limodzi mu molekyulu.

Kuyika & Kusunga

100g/500g/1kg/25kg kapena monga pempho;
Mankhwala osakhala owopsa, osungidwa mu vacuum pa kutentha kochepa (2-8°C).
(Kupaka kwapadera, palibe kuyimitsa. Palibe zoyendera za cryogenic zomwe zimafunikira.)
