Isingeniso

I-Methylphenyl ether (eyaziwa ngokuthi i-methylphenyl ether) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-p-tolusether:

 

Ikhwalithi:

I-Methylanisole iwuketshezi olungenambala olunephunga elimnandi elingavamile. Inhlanganisela izinzile emoyeni futhi ayishi ngaphandle kokuxhumana nama-oxidants aqinile.

 

Sebenzisa:

I-Methylanisole isetshenziswa kakhulu njenge-solvent ephilayo embonini. Incibilikisa izinto eziningi eziphilayo futhi ijwayele ukusetshenziselwa izinto zokumboza, izinto zokuhlanza, iglue, opende neziphunga eziwuketshezi. Iphinde isetshenziswe njengendlela yokusabela noma i-solvent kwezinye izimo ze-organic synthesis.

 

Indlela:

I-Methylanises ivamise ukulungiselelwa ukusabela kwe-etherification ye-benzene, futhi izinyathelo eziqondile ukusabela i-benzene ne-methanol lapho kukhona izisusa ze-asidi (ezifana ne-hydrochloric acid, i-sulfuric acid) ukukhiqiza i-methylanisole. Ekuphenduleni, i-acid catalyst isiza ukusheshisa ukusabela futhi ikhiqize umkhiqizo onesivuno esikhulu.

 

Ulwazi Lokuphepha:

Ama-Tolusoles ngokuvamile aphephile uma kuqhathaniswa ngaphansi kwezimo ezivamile zokusetshenziswa, kodwa okulandelayo kusafanele kuqashelwe:

1. Lapho isetshenziswa, indawo enomoya omuhle kufanele igcinwe ukuze kugwenywe ukunqwabelana komhwamuko wayo emoyeni.

3. Lapho ugcina futhi uphatha, ukuthintana nama-oxidants aqinile nezinto ezivuthayo kufanele kugwenywe ukuze kuvinjelwe izingozi zomlilo neziqhumane.

4. Inhlanganisela ingase ikhiphe amagesi anobuthi lapho ibola, edinga ukulahlwa kahle kwemfucuza nezincibilikizi.

5. Enqubweni yokusebenzisa nokuphatha i-methyl anisole, kuyadingeka ukuthi isebenze ngokuhambisana nemibandela yokusebenza kokuphepha efanele ukuze kuqinisekiswe ukuphepha komzimba womuntu kanye nemvelo.
