Intshayelelo

Methylcyclopentenolone. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:

 

Umgangatho:

- Imbonakalo: Ulwelo olungenambala

- Ivumba: Incasa yeziqhamo eziqholiweyo

- Ukunyibilika: Inyibilika emanzini, etywaleni nakwizinyibilikisi ze-ether

 

Sebenzisa:

 

Indlela:

- I-Methylcyclopentenolone inokulungiswa yi-catalytic dehydration reaction yotywala. Ii-catalysts ezisetyenziswa ngokuqhelekileyo ziyi-zinc chloride, i-alumina kunye ne-silicon oxide.

 

Ulwazi ngoKhuseleko:

- I-Methylcyclopentenolone yikhemikhali enetyhefu ephantsi.

- Incasa yayo eminty inokubangela ukungonwabi kwabanye abantu, kwaye ukuchasana okunokwenzeka okanye ukucaphuka kubeka umngcipheko emehlweni kunye nolusu.

- Kulumkele ukudibana kwamehlo nolusu kwaye usebenzise iindlela zokuzikhusela ezifana neeglavu kunye neeglasi.

- Ukuba uphefumle okanye utyiwe, funa unyango ngokukhawuleza.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
