Isingeniso

I-3,5-Dimethylphenol (eyaziwa nangokuthi i-m-dimethylphenol) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: I-3,5-dimethylphenol iyi-crystalline solid solid.

- Ukunyibilika: Kuyancibilika otshwaleni nakwi-ether futhi kuncibilika kancane emanzini.

- Iphunga: inephunga elimnandi elikhethekile.

- Izakhiwo zamakhemikhali: Kuyinhlanganisela ye-phenolic enezici zendawo yonke ze-phenol. Ingenziwa i-oxidized ngama-oxidizing agents kanye nokusabela okufana ne-esterification, i-alkylation, njll.

 

Sebenzisa:

- Ama-Chemical reagents: I-3,5-dimethylphenol ivame ukusetshenziswa njenge-reagent ku-organic synthesis kuma-laboratories.

 

Indlela:

I-3,5-Dimethylphenol ingalungiswa ngu:

I-Dimethylbenzene itholakala ngokusabela nge-bromine ngaphansi kwezimo ze-alkaline bese iphathwa nge-asidi.

I-Dimethylbenzene iphathwa nge-asidi bese ifakwa i-oxidized.

 

Ulwazi Lokuphepha:

- Ukuthinta isikhumba kungabangela ukucasuka nokungezwani komzimba, gqoka izinto zokuzivikela uma uzisebenzisa.

- Uma uhogelwe noma udliswa ngokweqile, kungabangela izimpawu zobuthi, njengesiyezi, isicanucanu, ukuhlanza, njll. Kufanele kuqashelwe ukuze kugwenywe ukungenwa ngephutha noma ukuhogela lapho ubamba.

- Sicela ubheke AmaSpredishithi Edatha Yezokuphepha afanelekile kanye Nemiyalelo Yokusebenza ukuze uyisebenzise futhi uyiphathe ngendlela efanele.
