Intshayelelo
I-1,2-Methylenedioxybenzene, ekwabizwa ngokuba yi-chunlanin, yi-organic compound. Oku kulandelayo kukwazisa ngeepropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-1,2-methylenedioxybenzene:
Umgangatho:
I-1,2-Methylenedioxybenzene lulwelo olungenambala nencasa enuka kamnandi. Iyanyibilika kwii-solvents ezininzi ze-organic, ezifana ne-alcohols kunye ne-ethers.
Sebenzisa:
I-1,2-Methylenedioxybenzene inoluhlu olubanzi losetyenziso. Isenokusetyenziswa nasekulungiseni idayi, iirubha, kunye neepolima.
Indlela:
I-1,2-Methylenedioxybenzene ingalungiswa ngokuphendula i-benzaldehyde nge-hydrogen peroxide. Iimeko zokusabela zingalawulwa yi-catalysts, njenge-ferric (III) bromide, njl.
Ulwazi ngoKhuseleko:
I-1,2-Methylenedioxybenzene iyacaphukisa kwaye ibangela amehlo. Iiglasi ezikhuselayo kunye neiglavu kufuneka zigqitywe ngexesha lokusebenza. Xa usebenzisa okanye uphethe le khompawundi, kuphephe ukuphefumla iigesi okanye ukudibana nolusu. I-1,2-Methylenedioxybenzene ikwalulwelo olunokutsha kwaye kufuneka ithintelwe kumadangatye kunye namabala obushushu obuphezulu. Xa ugcina kwaye usebenzisa, kuyimfuneko ukuthobela ingqalelo kwiimpawu ezichasene nokuqokelela komlilo kunye nombane ongatshintshiyo.
