4-Valeroylbiphenyl(CAS# 42916-73-4)

Intshayelelo

I-Bifenpentanone, ekwabizwa ngokuba yi-diphenopylacetone, yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-bifenpentanone:

Umgangatho:

- Imbonakalo: I-Bifenpentone yinto eqinileyo yekristale engenambala okanye etyheli.

- Ukunyibilika: Inyibilika kuninzi lwezinyibilikisi zendalo, ezinje ngotywala kunye neetha, kwaye zinyibilika kancinane emanzini.

- Iimpawu zeMichiza: I-Bifenpentone ineepropati ezinamandla zokunciphisa, kwaye njenge-compound esebenzayo, inokuthatha inxaxheba kwiintlobo ezahlukeneyo zeekhemikhali.

Sebenzisa:

Indlela:

Kukho iindlela ezininzi zokulungiselela i-bifenpentanone, kwaye iindlela ezisetyenziswa ngokuqhelekileyo ziquka:

- I-Benzophenone iphendula kunye ne-acetophenone phantsi kweemeko ze-acidic ukwenza i-bifenpentanone.

- Phambi kwe-sodium oxychloroxysulfate, i-benzophenone kunye ne-acetopyl bromoethylketone ifumana impendulo ye-etherification phantsi kweemeko ze-alkali ukufumana i-bifenpentanone.

Ulwazi ngoKhuseleko:

I-Bifenpentone ikhuselekile ngokubanzi phantsi kweemeko eziqhelekileyo zokusetyenziswa, kodwa oku kulandelayo kusafuneka kuqatshelwe:

- Kulumkele ukudibana nolusu namehlo, kwaye unxibe izixhobo ezifanelekileyo zokuzikhusela xa uzisebenzisa.

- Kulumkele ukudibana nezinto ezinokutsha kunye neeoksijini xa uzigcina ukuthintela iingozi zomlilo neziqhushumbo.

- Ingqalelo kufuneka ihlawulwe ekungeneni komoya ngexesha lokusetyenziswa kunye nokugcinwa ukuphepha ukuphefumla umphunga wayo.

- Kwimeko yokuphefumla ngempazamo okanye ukuvezwa kwi-bifenpentanone, hlamba ulusu lwakho ngokukhawuleza kwaye ufune uncedo lwezonyango.
