Unokukhupha umphunga oyityhefu. I-Benzene yi-compound ekungelula ukubola. Xa isabelana nezinye izinto zekhemikhali, isiseko sayo asitshintshi, kuphela i-athomu ye-hydrogen ekwiringi ye-benzene ithathelwa indawo ngamanye amaqela. Umphunga webenzene unokwenza umxube oqhumayo nomoya. Ulwelo lweBenzene lukhaphukhaphu kunamanzi, kodwa umphunga wawo unzima kunomoya. Kulula kakhulu ukubangela ukutshisa kunye nokuqhuma ebusweni bobushushu obuphezulu okanye umlilo ovulekileyo. Umphunga weBenzene unokusasaza kude, udibane nomthombo wokutshisa ekutshiseni, kunye nedangatye ecaleni kokubuyela umva. I-Benzene ixhomekeke kwisizukulwana kunye nokuqokelela kombane omileyo. Ukusabela kwe-benzene xa idibana ne-oxidant ibukhali. I-Benzene ayinyibiliki emanzini, kodwa i-soluble kutywala, i-ether, i-acetone, i-chloroform, i-petroli, i-carbon disulfide kunye nezinye izinyibilikisi eziphilayo.
Sebenzisa	Iikhemikhali ezisisiseko zemathiriyeli ekrwada, ezisetyenziswa njengezinyibilikisi kunye nezinto eziphuma kwi-benzene zokwenziwa, iziqholo, iidayi, iiplastiki, amayeza, iziqhushumbisi, irabha, njl.

Intshayelelo

I-Benzene lulwelo olungenambala nolubonakalayo olunevumba elimnandi elikhethekileyo. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-benzene:

Umgangatho:

1. I-Benzene iguquguquka kakhulu kwaye inokutsha, kwaye inokwenza umxube oqhumayo kunye neoksijini emoyeni.

2. Yinto enyibilikayo enokunyibilikisa izinto ezininzi eziphilayo, kodwa ayinakunyibilika emanzini.

3. I-Benzene i-conjugated aromatics compound kunye nesakhiwo sekhemikhali esizinzileyo.

4. Iimpawu zeekhemikhali zebenzene zizinzile kwaye akulula ukuhlaselwa yi-asidi okanye i-alkali.

Sebenzisa:

1. I-Benzene isetyenziswa ngokubanzi njengento ekrwada kwimizi-mveliso yokwenziwa kweeplastiki, irabha, idayi, iifiber zokwenziwa, njl.

2. I-derivative ebalulekileyo kwi-petrochemical industry, esetyenziselwa ukuvelisa i-phenol, i-benzoic acid, i-aniline kunye nezinye iikhompawundi.

3. I-Benzene isetyenziswa ngokuqhelekileyo njenge-solvent ye-organic synthesis reactions.

Indlela:

1. Ifunyenwe njengemveliso ephuma kwinkqubo yokucoca i-petroleum.

2. Ifunyenwe ngokuphendula kwe-dehydration ye-phenol okanye ukuchithwa kwe-tar yamalahle.

Ulwazi ngoKhuseleko:

1. I-Benzene sisiyobisi esiyityhefu, kwaye ukuba sesichengeni okanye ukuphefumla umphunga we-benzene ixesha elide kuya kubangela imingcipheko yempilo kumzimba womntu, kubandakanywa ne-carcinogenicity.

2. Xa usebenzisa i-benzene, kuyimfuneko ukugcina iimeko ezifanelekileyo zokungenisa umoya ukuqinisekisa ukuba umsebenzi uqhutyelwa kwindawo efanelekileyo.

3. Kulumkele ukudibana nolusu kunye nokuphefumla umphunga webenzene, kwaye unxibe izixhobo zokuzikhusela ezifana neeglavu zokhuselo kunye neziphefumli.

4. Ukutya okanye ukusela izinto ezine-benzene kuya kukhokelela kwityhefu, kwaye iinkqubo zokusebenza zokhuseleko kufuneka ziqwalaselwe ngokungqongqo.

5. Inkunkuma yebenzene kunye nenkunkuma ebandakanyeka kwibenzene kufuneka ilahlwe ngokuhambelana nemithetho nemigaqo efanelekileyo ukuthintela ukungcoliseka kwendalo kunye nokwenzakala.
