-Spices: Inogona kushandiswa semushonga kupa chikafu chakasarudzika flavour.
-Perfume industry: seimwe yezvisungo zveperfume essence.
Nzira:
(5h) furanone inogona kugadzirwa nematanho anotevera:
1. Ne 3-methyl -2-pentanone sechinhu chekutanga, 3-hydroxy -4-methyl -2-pentanone yakawanikwa neketo-alcohol reaction.
2.3-hydroxy -4-methyl -2-pentanone inobatwa ne etherifying agent (yakadai sediethyl ether) kugadzira chigadzirwa che etherification.
3. Chigadzirwa che etherification chinoiswa pasi pe acid catalysis uye deoxidation reaction kuti iwane furanone (5h).
Zvekuchengetedza
-(5h) furanone inoonekwa seyakachengeteka kushandiswa kwese, asi inogona kunge ichitsamwisa ganda nemeso pane yakanyanya kuwanda.
-Kushandisa kunofanirwa kutarisisa matanho ekudzivirira, kudzivirira kusangana neganda nemeso, uye kuchengetedza yakanyatso mhepo yekushanda nzvimbo.
-Tevedza maitiro ekuchengetedza akakodzera paunenge uchishandisa, uye uichengete munzvimbo yakaoma, inotonhorera, kure nemoto uye oxidizing agents.
