Marka ay la falgasho walxo kale oo kiimiko ah, qaabdhismeedkeeda aasaasiga ah isma beddelo, kaliya atomka hydrogen ee giraanta benzene ayaa lagu beddelaa kooxo kale. Uumiga benzene wuxuu sameyn karaa isku dhafka qarxa iyo hawo. Benzene dareere ah wuu ka fudud yahay biyaha, laakiin uumiga ayaa ka culus hawada.

Uumiga Benzene wuu fidsan karaa meel fog, wuxuu la kulmi karaa isha dabka ee shidda, iyo ololka socodka gadaal. Benzene waxay u nugul tahay abuurista iyo uruurinta korontad taagan. Dareen-celinta benzene ee taabashada oxidant waa mid daran. Benzene waa mid aan lagu milmi karin biyaha, laakiin waxay ku milmaan khamriga, ether, acetone, chloroform, gasoline, kaarboon disulfide iyo dareerayaasha kale ee dabiiciga ah.

Hordhac

Benzene waa dareere aan midab lahayn oo hufan oo leh ur gaar ah. Kuwa soo socdaa waa horudhac ku saabsan guryaha, isticmaalka, hababka diyaarinta iyo macluumaadka badbaadada benzene:

Tayada:

1. Benzene waa mid aad u kacsan oo guban karta, waxayna samayn kartaa isku dhafka qarxa iyo ogsijiinta hawada ku jirta.

2. Waa dareere dabiici ah oo milmi kara walxo badan oo dabiici ah, laakiin aan lagu milmi karin biyaha.

3. Benzene waa iskudhis caraf udgoon oo leh qaab dhismeed kiimiko oo deggan.

4. Waxyaabaha kiimikaad ee benzene waa kuwo deggan oo aan sahlanayn in lagu weeraro aashitada ama alkali.

Isticmaal:

1. Benzene waxaa si weyn loogu isticmaalaa sida alaabta ceeriin warshadaha ee soo saarista caagadaha, caag, midabada, fiilooyinka synthetic, iwm.

2. Waa derivative muhiim ah in warshadaha petrochemical, loo isticmaalo in lagu soo saaro phenol, benzoic acid, aniline iyo xeryahooda kale.

3. Benzene sidoo kale waxaa caadi ahaan loo isticmaalaa sida dareere loogu talagalay falcelinta synthesis organic.

Habka:

1. Waxa lagu helaa hab-soo-saar hab-socodka sifaynta batroolka.

2. Waxaa lagu helaa falcelinta fuuq-baxa ee phenol ama dildilaaca daamurka dhuxusha.

Macluumaadka Badbaadada:

1. Benzene waa walax sun ah, soo-gaadhista ama neefsashada muddada dheer ee uumiga benzene waxay u horseedi doontaa khataro caafimaad oo halis ah jidhka bini'aadamka, oo ay ku jiraan kansarka.

2. Marka la isticmaalayo benzene, waxaa lagama maarmaan ah in la ilaaliyo xaaladaha hawo wanaagsan si loo hubiyo in hawlgalka lagu fuliyo jawi ku habboon.

3. Ka fogow taabashada maqaarka iyo neefsashada uumiga benzene, oo xidho qalabka ilaalinta shakhsi ahaaneed sida galoofyada difaaca iyo qalabka neefsiga.

4. Cunista ama cabbitaanka walxaha ay ku jiraan benzene waxay horseedi doonaan sumowga, waana in si adag loo ilaaliyo hababka hawlgalka ee badbaadada.

5. Qashinka benzene iyo qashinka ku jira benzene waa in la daadiyaa si waafaqsan shuruucda iyo xeerarka ku haboon si looga fogaado wasakhowga iyo waxyeelada deegaanka.
