Mawu Oyamba
4-nitrobenzyl mowa. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 4-nitrobenzyl mowa:
Ubwino:
- 4-Nitrobenzyl mowa ndi kristalo wopanda mtundu wolimba wokhala ndi fungo lonunkhira bwino.
- Imakhala yosasunthika pa kutentha komanso kupanikizika, koma imatha kuyambitsa kuphulika ikakumana ndi kutentha, kugwedezeka, kukangana kapena kukhudzana ndi zinthu zina.
- Itha kusungunuka mu zosungunulira organic monga ma alcohols, ethers, ndi ma chlorinated hydrocarbons, komanso kusungunuka pang'ono m'madzi.
Gwiritsani ntchito:
- Mowa wa 4-nitrobenzyl ndi wofunikira wapakatikati mu kaphatikizidwe ka organic ndipo amagwiritsidwa ntchito kwambiri popanga mankhwala osiyanasiyana.
Njira:
- 4-Nitrobenzyl mowa amatha kupezedwa ndi kuchepetsa zomwe p-nitrobenzene ndi sodium hydroxide hydrate. Pali zinthu zambiri zenizeni ndi njira zomwe zimachitikira, zomwe nthawi zambiri zimachitika pansi pa acidic kapena zamchere.
Zambiri Zachitetezo:
- Mowa wa 4-Nitrobenzyl ndi wophulika ndipo uyenera kusungidwa kutali ndi moto wotseguka komanso kutentha kwambiri.
- Valani zida zodzitetezera zoyenera monga magolovu a labu, magalasi, ndi zovala zodzitchinjiriza mukamagwira ntchito.
- Kutsatiridwa mozama ndi machitidwe otetezeka ogwirira ntchito ndi malamulo kuyenera kuwonedwa panthawi yosungira ndi kusamalira.
- Samalirani zachitetezo cha chilengedwe ndikutsatira malamulo ndi miyezo yoyenera mukamagwiritsa ntchito kapena kutaya.
