Mawu Oyamba
Methylphenylacetic acid. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha p-tophenylacetic acid:
Ubwino:
- Maonekedwe: Maonekedwe odziwika a methylphenylacetic acid ndi olimba mwa kristalo woyera.
- Kusungunuka: Simasungunuka m'madzi koma imatha kusungunuka muzosungunulira zambiri.
Gwiritsani ntchito:
Njira:
- Njira yokonzekera yodziwika bwino imapezedwa ndi transesterification ya toluene ndi sodium carbonate. P-toluene imakhudzidwa ndi mowa, monga ethanol kapena methanol, kupanga p-toluene, yomwe imakhudzidwa ndi sodium carbonate kuti ipereke methylphenylacetic acid.
Zambiri Zachitetezo:
- Methylphenylacetic acid ndi yokhazikika kutentha kwa firiji ndipo imatha kuwola ndi kutentha kwambiri, magwero amoto kapena kuwala, kutulutsa zinthu zapoizoni.
- Njira zodzitetezera ziyenera kuchitidwa pogwira methamphenylacetic acid, monga kuvala zovala zoteteza maso, magolovesi ndi zovala zodzitetezera. Pewani kutulutsa mpweya, kumeza, kapena kukhudza khungu kuti musamve bwino kapena kuvulala.
- Methylphenylacetic acid iyenera kusungidwa kutali ndi kuyatsa, zopangira ma oxidizing amphamvu, ndi zitsulo zogwira ntchito pamalo owuma komanso mpweya wabwino.
