3,5-Dimethylphenol (kuma aka sani da m-dimethylphenol) wani fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga kaddarorin sa, amfaninsa, hanyoyin masana'anta da bayanan aminci:

 

inganci:

- Bayyanar: 3,5-dimethylphenol shine farin crystalline mai ƙarfi.

- Solubility: Yana narkewa a cikin barasa da ether kuma yana ɗan narkewa cikin ruwa.

- Kamshi: yana da kamshi na musamman.

- Sinadarai: Yana da fili mai phenolic tare da abubuwan duniya na phenol. Yana iya zama oxidized ta hanyar oxidizing jamiái da halayen kamar esterification, alkylation, da dai sauransu na iya faruwa.

 

Amfani:

- Chemical reagents: 3,5-dimethylphenol ne sau da yawa amfani da matsayin reagent a Organic kira a dakunan gwaje-gwaje.

 

Hanya:

3,5-Dimethylphenol za a iya shirya ta:

Ana samun Dimethylbenzene ta hanyar amsawa tare da bromine a ƙarƙashin yanayin alkaline sannan kuma a bi da shi da acid.

Ana bi da Dimethylbenzene tare da acid sannan kuma ya zama oxidized.

 

Bayanin Tsaro:

- Saduwa da fata na iya haifar da haushi da rashin lafiyan halayen, sanya kayan kariya na sirri lokacin amfani da su.

- Idan aka shaka ko kuma a sha da yawa, yana iya haifar da alamomin guba, kamar tashin hankali, tashin zuciya, amai da dai sauransu. Ya kamata a kiyaye don guje wa sha da wuri ko kuma numfashi yayin da ake shan magani.
