Abstract
Pronalazak se odnosi na postupak za prečišćavanje i izolovanje 3-α-fenil-β-acetiletil-4-hidroksikumarina i dobijanje njegove natrijumove soli, dobijene prema poznatom postupku. Posle uobičajene procedure obrade reakcione smese dobijen je, prekristalisavanjem iz acetona i benzena, beli prah koji je imao t.t.=161˚C. Ovo jedinjenje je predstavljalo 3-α-fenil-β-acetiletil-4-hidroksi kumarin. Njegov enolni oblik je sa rastvorom natrijum hidroksida pretvoren u natrijumovu so 3-α-fenil-β-acetiletil-4-hidroksikumarina, koja je uparavanjem pod sniženim pritiskom ili liofilizacijom dobijena u obliku belih kristala, t.t.=225˚-255˚C.The invention relates to a process for the purification and isolation of 3-α-phenyl-β-acetylethyl-4-hydroxycoumarin and the preparation of its sodium salt, obtained by a known method. Following the usual treatment procedure for the reaction mixture, a white powder having a mp = 161˚C was obtained by recrystallization from acetone and benzene. This compound represented 3-α-phenyl-β-acetylethyl-4-hydroxy coumarin. Its enol form was converted with sodium hydroxide solution into the 3-α-phenyl-β-acetylethyl-4-hydroxycoumarin sodium salt, which was obtained as white crystals by evaporation under reduced pressure or lyophilization, mp = 225˚-255˚C.
