Intshayelelo
I-Methylphenylacetic acid. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-p-tophenylacetic acid:
Umgangatho:
- Imbonakalo: Imbonakalo eqhelekileyo ye-methylphenylacetic acid yikristale emhlophe eqinileyo.
- Ukunyibilika: Ayinyibiliki kancinci emanzini kodwa inokunyibilika kuninzi lwezinyibilikisi zendalo.
Sebenzisa:
Indlela:
- Indlela eqhelekileyo yokulungiselela ifunyenwe nge-transesterification ye-toluene kunye ne-sodium carbonate. I-P-toluene isabela ngotywala, njenge-ethanol okanye i-methanol, ukuze yenze i-p-toluene, ethi emva koko iphendule nge-sodium carbonate ukunika i-methylphenylacetic acid.
Ulwazi ngoKhuseleko:
- I-Methylphenylacetic acid izinzile kwiqondo lokushisa kwaye inokubola phantsi kwamaqondo aphezulu, imithombo yomlilo okanye ukukhanya, ukuvelisa izinto ezinobuthi.
- Izilumkiso ezifanelekileyo kufuneka zithathwe xa kusingathwa i-methamphenylacetic acid, njengokunxiba iliso elikhuselayo, iiglavu kunye nempahla yokukhusela. Kuphephe ukuphefumla, ukungeniswa, okanye ukudibana kwesikhumba ukuphepha ukungonwabi okanye ukwenzakala.
- I-Methylphenylacetic acid kufuneka igcinwe kude ne-ignition, i-oxidizing agents eyomeleleyo, kunye neentsimbi ezisebenzayo kwindawo eyomileyo, kwindawo epholileyo.
