Isicelo
I-Burgess dehydrating agent, ebizwa nangokuthi i-Burgess reagent, i-methyl N-(triethylaminosulfuryl) carbamate.Ingaphelelwa amanzi ngaphansi kwezimo ezithambile futhi iyi-ejenti ekhethayo yokuqeda amanzi emzimbeni.Isetshenziselwa ukuguqula i-alcohol yesibili nephezulu enama-proton aseduze abe yi-alkenes.
Ingalungiswa ngokusabela kwe-chlorosulfone isocyanate ne-triethylamine ku-methanol.Ngesikhathi sokuphelelwa amanzi emzimbeni, isulfure ihlaselwa yiqembu le-hydroxyl, bese kuqedwa i-cis.Ama-ejenti aqeda amanzi e-Burgess angasetshenziswa futhi ukuze kuhlanganiswe izinhlanganisela ze-isonitrile ezivela ku-formamide.Indlela yokusabela ifana ne-xanthate yokuqeda ukusabela, futhi i-alkene iphinde itholakale ngokuqedwa kwe-cis yesimo soguquko sendandatho enamalungu ayisithupha ku-molecule.
Ukupakisha & Isitoreji
100g/500g/1kg/25kg noma njengesicelo;
Amakhemikhali angeyona ingozi, isitoreji esifakwe vacuum endaweni yokushisa ephansi (2-8°C).
(Ukupakishwa okukhethekile, akukho ukuvala ukusebenza. Azikho izinto zokuhamba ze-cryogenic ezidingekayo.)
