Intangiriro

3,5-Dimethylphenol (izwi kandi nka m-dimethylphenol) ni ifumbire mvaruganda. Ibikurikira nintangiriro yumutungo wacyo, imikoreshereze, uburyo bwo gukora namakuru yumutekano:

 

Ubwiza:

- Kugaragara: 3,5-dimethylphenol ni kirisiti yera ikomeye.

- Gukemura: Irashobora gushonga muri alcool na ether kandi igashonga gato mumazi.

- Impumuro: ifite impumuro idasanzwe.

- Imiterere yimiti: Nibintu bya fenolike hamwe nibintu rusange bya fenol. Irashobora guhindurwa na okiside ya okiside hamwe nibisubizo nka esterification, alkylation, nibindi birashobora kubaho.

 

Koresha:

- Imiti ya chimique: 3,5-dimethylphenol ikoreshwa nka reagent muri synthesis organique muri laboratoire.

 

Uburyo:

3,5-Dimethylphenol irashobora gutegurwa na:

Dimethylbenzene iboneka mugukorana na brom mugihe cya alkaline hanyuma ikavurwa na aside.

Dimethylbenzene ivurwa na aside hanyuma igahinduka okiside.

 

Amakuru yumutekano:

- Guhura nuruhu birashobora gutera uburakari na allergique, kwambara ibikoresho byokwirinda mugihe ubikoresha.

- Iyo uhumeka cyangwa winjijwe cyane, birashobora gutera ibimenyetso byuburozi, nko kuzunguruka, isesemi, kuruka, nibindi. Hagomba kwitonderwa kugirango wirinde guterwa nimpanuka cyangwa guhumeka mugihe ubikora.

- Nyamuneka reba impapuro z'umutekano zijyanye n'amabwiriza akoreshwa kugirango akoreshwe neza.
