I-4-Methylacetophenone (CAS# 122-00-9)

I-Methylacetophenone iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:

Ikhwalithi:
I-Methylacetophenone iwuketshezi olungenambala olunephunga elimnandi. Ayincibiliki emanzini kodwa ingancibilika kuzincibilikisi zemvelo njenge-ethanol nezincibilikisi ze-ether.

Sebenzisa:
I-Methylacetophenone ivame ukusetshenziswa njengento ebalulekile ekuhlanganiseni kwe-organic. Ingasetshenziswa futhi njengesengezo kwizincibilikisi, odayi, namakha.

Indlela:
Indlela yokulungiselela i-methylacetophenone itholakala ikakhulukazi ngokusabela kwe-ketation. Indlela evamile yokuhlanganisa iwukusabela i-acetophenone nge-reagent ye-methylation efana ne-methyl iodide noma i-methyl bromide ngaphansi kwezimo ze-alkaline. Ngemuva kokusabela, umkhiqizo ohlosiwe ungatholwa ngenqubo ye-distillation.

Ulwazi Lokuphepha:
- I-Methylacetophenone iyaguquguquka futhi kufanele isetshenziswe lapho kungena umoya.
- Gwema ukuthintana nama-oxidizing aqinile noma ama-asidi aqinile ukuze uvimbele ukusabela okuyingozi.
- I-Methoacetophenone iyacasula futhi kufanele igwenywe ukuthintana nesikhumba namehlo, futhi izinto zokuzivikela ezifanele ezifana namagilavu ​​nezibuko kufanele zigqokwe.
- Uma uhogela umoya noma ukumunca, funa usizo lwezokwelapha ngokushesha ngangokunokwenzeka.
- Lapho ugcina futhi uphatha i-methylacetophenone, landela imithetho yendawo futhi uthathe izinyathelo zokuphepha ezifanele.
