Intshayelelo

I-3,5-Dimethylphenol (eyaziwa nangokuthi i-m-dimethylphenol) i-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:

 

Umgangatho:

- Ukubonakala: I-3,5-dimethylphenol yikristale emhlophe eqinile.

- Ukunyibilika: Inyibilika etywaleni nakwi-ether kwaye inyibilika kancinane emanzini.

- Ivumba: inevumba elimnandi elikhethekileyo.

- Iimpawu zeMichiza: Yikhompawundi ye-phenolic eneempawu zendalo yonke ze-phenol. Inokuthi i-oxidized nge-oxidizing agents kunye neempendulo ezifana ne-esterification, alkylation, njl.

 

Sebenzisa:

- I-Chemical reagents: I-3,5-dimethylphenol isoloko isetyenziswa njenge-reagent kwi-organic synthesis kwiibhubhoratri.

 

Indlela:

I-3,5-Dimethylphenol ingalungiswa ngu:

I-Dimethylbenzene ifunyenwe ngokuphendula nge-bromine phantsi kweemeko ze-alkali kwaye iphathwa nge-asidi.

I-Dimethylbenzene iphathwa nge-asidi kwaye emva koko i-oxidized.

 

Ulwazi ngoKhuseleko:

- Ukudibana nolusu kunokubangela ukucaphuka kunye nokungaguquki, nxiba izixhobo zokuzikhusela xa uzisebenzisa.

- Xa ifakwe okanye ifakwe ngokugqithiseleyo, inokubangela iimpawu zetyhefu, ezifana nesiyezi, isicaphucaphu, ukuhlanza, njl.

- Nceda ubhekisele kwiiNgcaciso zeeNkcukacha zoKhuseleko ezifanelekileyo kunye neMiyalelo yokuSebenza yokusetyenziswa ngokufanelekileyo kunye nokuphatha.
