Isingeniso
I-methylphenylacetic acid. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-p-tophenylacetic acid:
Ikhwalithi:
- Ukubukeka: Ukubukeka okuvamile kwe-methylphenylacetic acid i-crystalline solid solid.
- Ukunyibilika: Ayincibiliki kancane emanzini kodwa ingancibilika kuzincibilikisi eziningi eziphilayo.
Sebenzisa:
Indlela:
- Indlela evamile yokulungiselela itholakala nge-transesterification ye-toluene ne-sodium carbonate. I-P-toluene isabela notshwala, njenge-ethanol noma i-methanol, ukuze yakhe i-p-toluene, ebese isabela nge-sodium carbonate ukunikeza i-methylphenylacetic acid.
Ulwazi Lokuphepha:
- I-Methylphenylacetic acid izinzile ekamelweni lokushisa futhi ingabola ngaphansi kwamazinga okushisa aphezulu, imithombo yomlilo noma ukukhanya, ikhiqize izinto ezinobuthi.
- Izinyathelo ezifanele kufanele zithathwe lapho uphatha i-methamphenylacetic acid, njengokugqoka amehlo okuzivikela, amagilavu nezingubo zokuzivikela. Gwema ukuhogela, ukumunca, noma ukuthinta isikhumba ukuze ugweme ukungaphatheki kahle noma ukulimala.
- I-methylphenylacetic acid kufanele igcinwe kude nokuvutha, ama-oxidizing aqinile, nezinsimbi ezisebenzayo endaweni eyomile, enomoya omuhle.
