Isingeniso

I-1,2-Methylenedioxybenzene, eyaziwa nangokuthi i-chunlanin, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-1,2-methylenedioxybenzene:

 

Ikhwalithi:

I-1,2-Methylenedioxybenzene iwuketshezi olungenambala olunokunambitheka okumnandi. Incibilika kuzincibilikisi eziningi eziphilayo, njengotshwala nama-ether.

 

Sebenzisa:

I-1,2-Methylenedioxybenzene inezinhlobonhlobo zokusetshenziswa. Ingasetshenziswa futhi ekulungiseni odayi, amarabha, nama-polymer.

 

Indlela:

I-1,2-Methylenedioxybenzene ingalungiswa ngokuphendula i-benzaldehyde nge-hydrogen peroxide. Izimo zokusabela zingalawulwa ama-catalysts, njenge-ferric(III) bromide, njll.

 

Ulwazi Lokuphepha:

I-1,2-Methylenedioxybenzene iyacasula futhi iheha iso. Izibuko zokuzivikela namagilavu ​​kufanele kugqokwe ngesikhathi sokusebenza. Uma usebenzisa noma uphatha lesi sakhi, gwema ukuhogela amagesi noma ukuthintana nesikhumba. I-1,2-Methylenedioxybenzene iwuketshezi oluvuthayo futhi kufanele igwenywe emalangabini nasezindaweni zokushisa okuphezulu. Lapho ugcina futhi usebenzisa, kuyadingeka ukuthi unake izinyathelo zokuvikela ukuqoqwa komlilo kanye nogesi omile.
