Isingeniso
I-P-hydroxyvalerone iyinhlanganisela yezinto eziphilayo. Okulandelayo isingeniso esiningiliziwe sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-p-hydroxypenterone:
Ikhwalithi:
I-P-hydroxyvalerone iwuketshezi olungenambala olunokunambitheka okuyingqayizivele kwephunga elimnandi. Ingancibilika ngamanzi kanye nezincibilikisi eziningi eziphilayo njenge-ethanol ne-ether.
Sebenzisa:
I-P-hydroxyvalerone isetshenziswa kabanzi embonini yamakhemikhali. Kuyi-solvent ebalulekile futhi ivame ukusetshenziswa ekulungiseni amapende, ama-inki nama-varnish. I-P-hydroxypentanone ingasetshenziswa futhi njengento yokwenziwa yokwenziwa yamakha, njengamakha nama-flavour.
Indlela:
Kunezindlela eziningana zokulungiselela i-p-hydroxypenterone. Enye yezindlela ezivame ukusetshenziswa ukuthola i-p-hydroxypentanone ngokusabela kwe-asidi-catalyzed ye-benzoic acid ne-acetone. Enye indlela itholakala nge-transesterification ye-benzoic acid ne-acetone, ilandelwa yi-acid hydrolysis.
Ulwazi Lokuphepha:
I-P-hydroxyvalerone iwuketshezi oluvutha umlilo lapho umhwamuko wawo ungakha izingxube ezivuthayo noma eziqhumayo ngomoya. Lapho uphatha futhi usetshenziswa, izinyathelo zokuvimbela umlilo kufanele zithathwe futhi ukuxhumana namalangabi avulekile kanye nemithombo yokushisa ephezulu kufanele kugwenywe. I-P-hydroxyvalerone inomphumela ocasulayo futhi owonakalisayo emehlweni nasesikhumbeni, futhi ukuthintana ngqo kufanele kugwenywe. Izimpahla zokuzivikela ezifanele ezifana namagilavu nezibuko kufanele zigqokwe ngesikhathi sokusetshenziswa.
