Abstract

Postupak za dobijanje trans-β-(aroil)-α,β-oksiran-propanskih kiselina opšte formule gde su značenja supstituenta: R1 predstavlja vodonik, hlor i metil; R2 predstavlja vodonik; R3 predstavlja metil, etil, izopropil, butil, tercbutil, f1uor, hlor i brom; R4, predstavlja vodonik; R5 predstavlja vodonik, naznačen time, što se odgovarajuće trans-β-(aroil)akrilne kiseline suspenduju u vodi i dodaje natrijum hidroksid takvom brzinom da temperatura ne pređe 200C i pH ne pređe 9, dok se sva kiselina ne rastvori, i zatim doda 1,5-3,5 molarni višak vodonik peroksida i pH održava na 8,5 ± 0,5 daljim dodavanjem natrijum hidroksida. Prijava sadrži još 2 zahteva.A process for the preparation of trans-β- (aroyl) -α, β-oxirane-propanoic acids of the general formula wherein the meanings of the substituent are: R 1 represents hydrogen, chlorine and methyl; R2 represents hydrogen; R3 represents methyl, ethyl, isopropyl, butyl, tert-butyl, fluoro, chloro and bromo; R4 represents hydrogen; R5 is hydrogen, wherein the corresponding trans-β- (aroyl) acrylic acids are suspended in water and sodium hydroxide is added at a rate not exceeding 200C and the pH not exceeding 9, until all the acid has dissolved, and then 1 , A 5-3.5 molar excess of hydrogen peroxide and pH was maintained at 8.5 ± 0.5 by further addition of sodium hydroxide. The application contains 2 more requests.
