Mawu Oyamba

Methylphenyl ether (yotchedwa methylphenyl ether) ndi organic compound. Zotsatirazi ndikuwulula za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha p-tolusether:

 

Ubwino:

Methylanisole ndi madzi opanda mtundu okhala ndi fungo lonunkhira bwino. Pawiriyi imakhala yosasunthika mumlengalenga ndipo sungapse popanda kukhudzana ndi ma okosijeni amphamvu.

 

Gwiritsani ntchito:

Methylanisole amagwiritsidwa ntchito makamaka ngati zosungunulira za organic m'makampani. Amasungunula zinthu zambiri zakuthupi ndipo amagwiritsidwa ntchito kwambiri popaka, zotsukira, zomatira, utoto ndi fungo lamadzimadzi. Amagwiritsidwanso ntchito ngati reaction sing'anga kapena zosungunulira zina organic synthesis zimachitikira.

 

Njira:

Methylanises nthawi zambiri amakonzedwa ndi etherification reaction ya benzene, ndipo masitepe enieni ndikuchita benzene ndi methanol pamaso pa zopangira asidi (monga hydrochloric acid, sulfuric acid) kupanga methylanisole. Pochitapo kanthu, chothandizira cha asidi chimathandizira kufulumizitsa zomwe zikuchitika ndikupanga zokolola zambiri.

 

Zambiri Zachitetezo:

Tolusoles nthawi zambiri amakhala otetezeka pakagwiritsidwe ntchito wamba, koma zotsatirazi ziyenera kudziwidwa:

1. Akagwiritsidwa ntchito, malo olowera mpweya wabwino ayenera kusamalidwa kuti mpweya wake usawunjike mumlengalenga.

3. Posunga ndi kunyamula, kukhudzana ndi ma okosijeni amphamvu ndi zoyaka moto ziyenera kupewedwa kuti mupewe ngozi zamoto ndi kuphulika.

4. Mankhwalawa amatha kutulutsa mpweya wapoizoni akawola, zomwe zimafuna kutaya zinyalala ndi zosungunulira moyenera.

5. Pogwiritsa ntchito ndi kugwiritsira ntchito methyl anisole, m'pofunika kugwira ntchito motsatira ndondomeko yoyenera yachitetezo kuti zitsimikizire chitetezo cha thupi la munthu ndi chilengedwe.
