Nhanganyaya
Methylphenylacetic acid. Inotevera sumo yezvivakwa, mashandisirwo, nzira dzekugadzirira uye ruzivo rwekuchengetedza p-totophenylacetic acid:
Hunhu:
- Chitarisiko: Chitarisiko chakajairika chemethylphenylacetic acid ichena crystalline yakasimba.
- Solubility: Iyo isinganyanyi kunyungudika mumvura asi inogona kunyungudika mune yakawanda organic solvents.
Shandisa:
Nzira:
- Nzira yakajairika yekugadzirira inowanikwa ne transesterification ye toluene uye sodium carbonate. P-toluene inopindirana nedoro, senge ethanol kana methanol, kuumba p-toluene, iyo inobva yaitwa ne sodium carbonate kupa methylphenylacetic acid.
Zvekuchengetedza
- Methylphenylacetic acid inogadzikana patembiricha yekamuri uye inogona kuora pasi pekupisa kwakanyanya, zvitubu zvemoto kana mwenje, ichigadzira zvinhu zvine chepfu.
- Kuchengetedza kwakakodzera kunofanirwa kutorwa kana uchibata methamphenylacetic acid, sekupfeka maziso ekudzivirira, magirovhosi uye zvipfeko zvinodzivirira. Dzivisa inhalation, kupinza, kana kubata ganda kudzivirira kusagadzikana kana kukuvara.
- Methylphenylacetic acid inofanirwa kuchengetwa kure nekupisa, yakasimba oxidizing agents, uye simbi dzinoshanda munzvimbo yakaoma, ine mhepo yakanaka.
