Mawu Oyamba

Benzene ndi madzi opanda mtundu komanso owoneka bwino okhala ndi fungo lonunkhira lapadera. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chitetezo cha benzene:

Ubwino:

1. Benzene imakhala yosasunthika komanso yoyaka, ndipo imatha kupanga chisakanizo chophulika ndi okosijeni mumlengalenga.

2. Ndi organic zosungunulira zomwe zimatha kusungunula zinthu zambiri, koma sizisungunuka m'madzi.

3. Benzene ndi conjugated onunkhira pawiri ndi khola mankhwala kapangidwe.

4. Mankhwala a benzene ndi okhazikika komanso osavuta kugwidwa ndi asidi kapena alkali.

Gwiritsani ntchito:

1. Benzene imagwiritsidwa ntchito kwambiri ngati mafakitale opanga mapulasitiki, mphira, utoto, ulusi wopangira, etc.

2. Ndikofunikira kwambiri pamakampani a petrochemical, omwe amagwiritsidwa ntchito popanga phenol, benzoic acid, aniline ndi mankhwala ena.

3. Benzene imagwiritsidwanso ntchito ngati chosungunulira cha organic synthesis reaction.

Njira:

1. Imapezedwa ngati chinthu chochokera pakuyenga mafuta.

2. Amapezedwa ndi kuchepa kwa madzi m'thupi kwa phenol kapena kuphulika kwa phula la malasha.

Zambiri Zachitetezo:

1. Benzene ndi chinthu chapoizoni, ndipo kukhudzana kwa nthawi yayitali kapena kupuma mpweya wambiri wa benzene kungayambitse thanzi la munthu, kuphatikizapo carcinogenicity.

2. Mukamagwiritsa ntchito benzene, ndikofunikira kusunga mpweya wabwino kuti zitsimikizire kuti ntchitoyi ikuchitika pamalo oyenera.

3. Pewani kukhudza khungu ndi kupuma mpweya wa benzene, komanso valani zida zodzitetezera monga magolovesi oteteza ndi zopumira.

4. Kudya kapena kumwa zinthu zomwe zili ndi benzene kungayambitse poyizoni, ndipo njira zotetezera ziyenera kutsatiridwa mosamalitsa.

5. Zinyalala za benzene ndi zinyalala zomwe zili mu benzene ziyenera kutayidwa motsatira malamulo ndi malamulo oyenera kupewa kuwononga chilengedwe ndi kuvulaza.
