Isingeniso

I-Cresol, eyaziwa ngamakhemikhali ngokuthi i-methylphenol (igama lesiNgisi elithi Cresol), iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-p-toluenol:

Ikhwalithi:

Ukubukeka: I-Cresol iwuketshezi olungenambala noma oluphuzi olunephunga elikhethekile le-phenolic.

Ukunyibilika: Kuncibilika kuma-alcohols, ethers nama-ether, futhi kuncibilika kancane emanzini.

Izici zekhemikhali: I-Cresol into ene-asidi ehlangana ne-alkali yakhe usawoti ohambisanayo.

Sebenzisa:

Ukusetshenziswa kwezimboni: I-Cresol isetshenziswa njengesilondolozi, isibulala-magciwane, kanye nesincibilikisi lapho kwakhiwa izivimbelakuvunda. Iphinde isebenze njenge-catalyst kanye ne-solvent ezimbonini zenjoloba ne-resin.

Ukusetshenziswa kwezolimo: I-toluene ingasetshenziswa emkhakheni wezolimo njengesibulala-zinambuzane nesibulala-sikhunta.

Indlela:

Ziningi izindlela zokwenza i-toluenol, enye yazo evame ukusetshenziswa ukuyithola ngokusabela kwe-oxidation ye-toluene. Isinyathelo esiqondile esokuqala ukuphendula i-toluene nge-oxygen ukuze kukhiqizwe i-toluol ngaphansi kwesenzo se-catalyst.

Ulwazi Lokuphepha:

I-Cresol inobuthi, futhi ukuthintana ngokuqondile noma ukuhogela inani elikhulu le-cresol kungaba yingozi empilweni. Izinqubo zokusebenza zokuphepha ezifanele kufanele zilandelwe lapho zisetshenziswa, futhi kufanele kusetshenziswe izinto zokuzivikela ezifanele.

Gwema ukuthintana isikhathi eside nesikhumba futhi ugweme ukuhogela umhwamuko waso.

Lapho ugcina futhi uphatha i-toluenol, idinga ukuvalwa kahle futhi igcinwe kude nokushisa kanye nokushisa okuphezulu.

Okwedlule: I-Phenol(CAS#108-95-2)

Olandelayo: I-Ethyl maltol(CAS#4940-11-8)
