I-2-naphthol - ukuzimisela komthamo wamanzi

GB/T 1646-2012 2-naphthol

Umda we

Lo mgangatho uchaza iimfuno, isampuli, iindlela zokuvavanya, imithetho yokuhlola, kunye nokumakisha, ukulebula, ukupakishwa, ukuthutha kunye nokugcinwa kwe-2-naphthol.

Lo mgangatho usebenza kulawulo lomgangatho weemveliso ze-2-naphthol.

Ifomula:

Umfanekiso

Ifomula yemolekyuli: C10H8O

Ubunzima bemolekyuli: 144.17(ngokobunzima be-athomu yamazwe ngamazwe ka-2007)

I-CAS RN: 135-19-3

iimfuno

Iimfuno zomgangatho we-2-naphthol ziya kuhambelana neemfuno kwiThebhile 1.

Umfanekiso

Indlela yovavanyo ye

Ukuzimisela kokufuma

Ngokutsho kwe-3.4 "Karl Fischer Method kunye ne-Karl Fischer Modification Method "kwi-GB / T 2386-2006.

Umthamo wesampuli ye-2-naphthol yi-2g.

Umahluko phakathi kweziphumo ezimbini zokulinganisa kufuneka ungabi ngaphezu kwe-0.02% (iqhezu lobunzima), kwaye i-arithmetic mean yeziphumo ezimbini zokulinganisa kufuneka ithathwe njengesiphumo somlinganiselo.

Ixabiso kunye nomgangatho wemveliso uyathetha,
Ukuba ucinga ukuba ixabiso liphezulu, thumela isampuli ukujonga umgangatho.Isampulu #isimahla.
Faka iodolo kwangethuba kwaye ubuye kwangethuba.Ixabiso langoku lihlala linyuka.Ukuba usathandabuza, yiza kum ukuze ndikubuze kwaye uthethe.
I-2- #Naphthol, ephantsi kunentengiso #ixabiso, ingasetyenziselwa #ikhemesti kunye nemveliso yedayi.Iitoni ezingama-20 zokugqibela zeempahla ezinexabiso elihle ziya kuthengiswa kwaye ixabiso liya kunyuka.
Isetyenziswa ekulungiseleleni #Tobias acid, #J acid, 2.3-asidi, kunye nokulungiswa # anti-aging agent D, anti-aging agent #DNP kunye ne-anti-aging agent, #organic pigment kunye #bactericide .
