Intshayelelo
I-P-hydroxyvalerone yi-organic compound. Oku kulandelayo kukwaziswa okuneenkcukacha kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-p-hydroxypenterone:
Umgangatho:
I-P-hydroxyvalerone lulwelo olungenambala kunye nencasa eyodwa enevumba elimnandi. Inokunyibilika ngamanzi kunye nezinyibilikisi ezininzi eziphilayo ezifana ne-ethanol kunye ne-ether.
Sebenzisa:
I-P-hydroxyvalerone isetyenziswa ngokubanzi kwishishini lemichiza. I-solvent ebalulekileyo kwaye isetyenziswa ngokuqhelekileyo ekulungiseleleni iipende, ii-inki kunye neevanishi. I-P-hydroxypentaone ingasetyenziswa njengento ekrwada yokwenziwa kwiziqholo, ezifana neziqholo kunye neziqholo.
Indlela:
Kukho iindlela ezininzi zokulungiselela i-p-hydroxypenterone. Enye yeendlela ezisetyenziswa ngokuqhelekileyo kukufumana i-p-hydroxypentanone nge-acid-catalyzed reaction ye-benzoic acid kunye ne-acetone. Enye indlela ifunyenwe nge-transesterification ye-benzoic acid kunye ne-acetone, ilandelwa yi-acid hydrolysis.
Ulwazi ngoKhuseleko:
I-P-hydroxyvalerone lulwelo olunokutsha umphunga onokuthi wenze imixube enokutsha okanye eqhushumbayo ngomoya. Xa uphatha kunye nokusetyenziswa, amanyathelo okuthintela umlilo kufuneka athathwe kwaye udibanise nomlilo ovulekileyo kunye nemithombo yokushisa ephezulu kufuneka igwenywe. I-P-hydroxyvalerone inomphumo ocaphukisayo kunye ne-corrosion emehlweni kunye nolusu, kwaye ukudibanisa ngokuthe ngqo kufuneka kugwenywe. Izixhobo ezifanelekileyo zokuzikhusela ezinje ngeeglavu kunye neeglavu kufuneka zinxitywe ngexesha lokusetyenziswa.
