Intshayelelo

I-P-ethylnitrobenzene (isifinyezo: DEN) yinxalenye yezinto eziphilayo. Oku kulandelayo kukwazisa ngeepropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-ethylnitrobenzene:

 

Umgangatho:

1. Imbonakalo: I-P-ethylnitrobenzene lulwelo olungenambala ukuya kumthubi okhanyayo.

2. Ukunyibilika: i-p-ethylnitrobenzene iyanyibilika kwiialkoholi kunye nezinyibilikisi ze-ether eziphilayo.

 

Sebenzisa:

1. Ukwenziwa kweziqhushumbisi: i-p-ethylnitrobenzene ingasetyenziswa njengento ekrwada kwiziqhushumbisi ezinamandla aphezulu, ezifana ne-synthesis ye-TNT (trinitrotoluene).

2. Intambo eqhumayo: I-P-ethylnitrobenzene ikwasetyenziswa njengenxalenye yentambo yokuqhushumba.

3. I-Chemical synthesis: i-p-ethylnitrobenzene yinto ebalulekileyo ephakathi kwi-organic synthesis kwaye ingasetyenziselwa ukudibanisa ezinye iikhompawundi.

 

Indlela:

Ukulungiswa kwe-p-ethylnitrobenzene kungasetyenziselwa ukusabela kwi-styrene kunye ne-nitric acid ukwenza i-p-ethylaryl nitrate, kwaye iphathwe nge-asidi ye-sulfuric ukufumana i-p-ethylnitrobenzene.

 

Ulwazi ngoKhuseleko:

1. I-P-ethylnitrobenzene lulwelo olunokutsha kwaye kufuneka lugcinwe kude nomlilo kunye namaqondo obushushu aphezulu.

2. Xa uphethe i-p-ethylnitrobenzene, nxiba iiglavu ezikhuselayo kunye nezibuko ukuze ugweme ukudibana nolusu namehlo.

3. I-P-ethylnitrobenzene inetyhefu ethile kokusingqongileyo kwaye inqanda ukukhutshelwa emanzini nasemhlabeni.

4. Amanyathelo okhuseleko kufuneka alandelwe xa ugcina kwaye uphethe i-p-ethylnitrobenzene.

5. Xa uzama ukusebenzisa i-p-ethylnitrobenzene, kufuneka yenziwe kwilabhorethri engenamoya ukuphepha ukuphefumla umphunga wayo.
