Isingeniso

I-Phenophenol, eyaziwa nangokuthi i-benzene sulfide, iwuketshezi olungenambala ukuya kokuphuzi. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-phenol:

 

Ikhwalithi:

- Ukubukeka: I-Phenophenol iwuketshezi olungenambala ukuya kokuphuzi olukhanyayo olunephunga elingavamile le-thiophenol.

- Ukunyibilika: I-Phenophenol ayincibiliki emanzini, kodwa incibilika kuzincibilikisi eziningi eziphilayo ezifana notshwala, ama-ether, ama-alcohol ether, njll.

- Ukusebenza kabusha: I-Phenophenol i-electrophilic futhi ingangena kwi-acid-base neutralization, i-oxidation, kanye nokushintshwa.

 

Sebenzisa:

- Imboni yamakhemikhali: I-Phenophenol ingasetshenziswa njengendawo ephakathi ekukhiqizeni odayi, amapulasitiki, nenjoloba.

- Izivimbelakuvunda: I-Phenol ine-antibacterial ethile, inhibition yesikhunta kanye nemisebenzi ye-antiseptic, futhi isetshenziswa kakhulu ekuvikelweni kwezinkuni, amapende, ama-adhesives nezinye izinkambu.

 

Indlela:

I-Phenol ingalungiswa ngokusabela kwe-benzenesulfonyl chloride nge-sodium hydrosulfide. Ekuphenduleni, i-benzenesulfonyl chloride ihlangana ne-sodium hydrogen sulfide ukwenza i-benzene mercaptan, ebuye ifakwe i-oxid ukuze kutholwe i-phenylthiophenol.

 

Ulwazi Lokuphepha:

- I-Phenophenol iyacasula futhi ingase ibangele ukuvuvukala lapho uxhumane nesikhumba noma amehlo. Ukuthintana ngqo nesikhumba namehlo kufanele kugwenywe uma usebenzisa i-thiophenol, futhi amagilavu ​​okuzivikela kanye nezibuko kufanele kugqokwe uma kunesidingo.

- I-Phenophenol inobuthi emvelweni futhi kufanele igwenywe ngokuvuza okukhulu futhi ikhiphe emithonjeni yamanzi noma emhlabathini.

- I-Phenophenol iyashintshashintsha futhi ingase ibangele izimpawu ezifana nesiyezi nesicanucanu uma ibekwe kuyo endaweni engenawo umoya isikhathi eside. Indawo yokusebenza enomoya omuhle kufanele igcinwe lapho kusetshenziswa i-phenothiophenol.
