Daim ntawv thov
Burgess dehydrating agent, tseem hu ua Burgess reagent, yog methyl N-(triethylaminesulfuryl) carbamate.Nws tuaj yeem dehydrated nyob rau hauv cov mob me me thiab yog ib qho kev xaiv me me dehydrating tus neeg sawv cev.Nws yog siv los hloov cov cawv theem nrab thiab theem nrab nrog cov protons uas nyob ib sab mus rau alkenes.
Nws tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm chlorosulfone isocyanate thiab triethylamine hauv methanol.Thaum lub sij hawm lub cev qhuav dej, sulfur raug tawm tsam los ntawm pawg hydroxyl, thiab tom qab ntawd cis tshem tawm tshwm sim.Burgess dehydrating agents kuj tuaj yeem siv los ua ke cov tshuaj isonitrile los ntawm formamide.Cov tshuaj tiv thaiv mechanism zoo ib yam li xanthate tshem tawm cov tshuaj tiv thaiv, thiab cov alkene kuj tau los ntawm cis tshem tawm ntawm kev hloov pauv ntawm lub nplhaib rau lub nplhaib hauv cov molecule.
Ntim & Cia
100g / 500g / 1kg / 25kg los yog raws li kev thov;
Cov tshuaj tsis muaj teeb meem, lub tshuab nqus tsev cia ntawm qhov kub qis (2-8 ° C).
