Phenolyindawo eqhelekileyo yezinto eziphilayo, ebizwa ngokuba yi-carbolic acid. Yinto engenamibala okanye emhlophe eqinile i-odor eyomeleleyo. Isetyenziswa ikakhulu kwimveliso yeedayi, imiphetho, iiplastiki, i-lebrizers, iintsholongwane, njl njl. Ukongeza, ikwayimveliso ebalulekileyo ephakathi kwishishini lekhemikhali.

Phenol

 

Ekuqaleni kwenkulungwane yama-20, uPhenol wafunyanwa enetyhefu eyomeleleyo emzimbeni womntu, kwaye ukusetyenziswa kwayo ekuvelisweni kwabahlali kunye nezinye iimveliso bezitshintshwa zezinye izinto. Ngo-1930s, ukusetyenziswa kwe-phenol kwi-cosmetics kunye nezindlu zangasese kwavalwa ngenxa yetyhefu yetyhefu yayo kunye neodor. Ngo-1970s, ukusetyenziswa kwe-phenol kwizicelo ezininzi zemveliso kwavalwa ngenxa yokungcoliseka kwendalo esingqongileyo kunye neengozi zempilo zabantu.

 

EUnited States, ukusetyenziswa kwe-phenol kumzi-mveliso kulawulwa ngokungqongqo ukusukela kwiminyaka yoo-1970. I-Arhente yoKhuseleko lweSizwe se-US (i-EPA) iseke uthotho lwemithetho nemigaqo yokunciphisa ukusetyenziswa kunye nokuphuma kwe-phenol ukwenzela ukukhusela impilo yabantu kunye nokusingqongileyo. Umzekelo, imigangatho yokukhupha i-phenol kumanzi amdaka sele ichazwe ngokungqongqo, kwaye ukusetyenziswa kwe-phenol kwiinkqubo zemveliso kunqatshelwe. Ukongeza, i-FDA (i-FDA (i-FDA kunye neziyobisi) iye yamisela uthotho lwemigaqo ukuqinisekisa ukuba izongezo zokutya kunye ne-cosmetics ayinayo i-phenol okanye izahlulo zayo.

 

Ukuqukumbela, nangona i-phenol inoluhlu olubanzi lwezicelo kumashishini kunye nobomi bemihla ngemihla, ityhubhuli yetyhefu ye-odor ibangele ukonakala kakhulu kwimpilo yabantu kunye nokusingqongileyo. Ke ngoko, amazwe amaninzi athathile amanyathelo okuthintela ukusetyenziswa kwayo kunye nokuphuma kwayo. E-United States, nangona ukusetyenziswa kwe-phenol kumzi-mveliso kulawulwa ngokungqongqo, kusenziwa ngokubanzi kwizibhedlele nakwamanye amaziko onyango njengentsholongwane kunye ne-sterlate. Nangona kunjalo, ngenxa yobungozi bayo obuphezulu kunye nengozi yempilo enokubakho, kuyacetyiswa ukuba abantu bakuphephe ukunxibelelana ne-phenol kangangoko kunokwenzeka.
