Isingeniso

I-Resorcinol yaziwa nangokuthi i-2,3,5-trihydroxyanisole. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-resorcinol:

 

Ikhwalithi:

- Ukubukeka: I-Resorcinol iyikristale eqinile emhlophe kuya kokuphuzi okuphaphathekile.

- I-Solubility: I-Resorcinol iyancibilika emanzini, i-ethanol nezincibilikisi ze-ether.

 

Sebenzisa:

- Izivimbelakuvunda: I-Resorcinol inezindawo ezinhle zokulwa namagciwane futhi ingasetshenziswa njengesivikelo, evame ukusetshenziswa okhuni, ephepheni, ngopende kanye nezinye izindlela zokwelapha ezibulala amagciwane.

- Iziphakathi zikadayi wokwenziwa: Aqukethe amaqembu amaningi e-hydroxyl esakhiweni sawo futhi angasetshenziswa ukwenza okuphakathi kwezinhlanganisela zezinto eziphilayo ezinjengodayi namakha.

- Ezinye izinhlelo zokusebenza: I-Resorcinol ingasetshenziswa futhi njengesilondolozi kanye ne-antioxidant ezintweni ezifana nezinsalela zokwenziwa, irabha, namapulasitiki.

 

Indlela:

I-Resorcinol ingalungiswa ngezindlela ezihlukahlukene, futhi indlela eyodwa evame ukusetshenziswa ukuyithola ngokuphendula i-phenol ne-hydrazine hydrate ngaphansi kwezimo ze-acidic.

 

Ulwazi Lokuphepha:

I-Phloroglucinol inobuthi emzimbeni womuntu, futhi ukuchayeka ngokweqile noma ukuhogela kungase kubangele ukucasuka esikhumbeni, emehlweni, nasohlelweni lokuphefumula.

- Kufanele kuqashelwe ukuvimbela ukuthintana nama-oxidants aqinile nama-asidi aqinile ngesikhathi sokuphatha nokugcinwa ukuze kugwenywe ukusabela kwamakhemikhali okuyingozi.

- Izinto zokuzivikela ezinjengamagilavu, izibuko, nezihlangu zobuso kufanele zigqokwe kahle lapho kusetshenziswa i-resorcinol futhi kugwenywe ukuthintana ngokuqondile noma ukuhogela.

- Landela izinqubo ezifanele zokuphatha kanye nokulahla ukuze kuncishiswe ukungcoliswa kwemvelo.
