Mawu Oyamba

Ethyl allylenate. Zotsatirazi ndikuyambitsa katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha ethyl allylate:

 

Ubwino:

- Ethyl allyl proponate ndi madzi omwe ali ndi fungo lamphamvu, amasungunuka m'madzi osiyanasiyana monga ma alcohols, ethers, etc., koma osasungunuka m'madzi.

- Ethyl allyl proponate imakhala yokhazikika, koma polymerization imapezeka padzuwa.

 

Gwiritsani ntchito:

- Ethyl allyl propionate ndi gawo lapakati lofunikira pakuphatikizika kwachilengedwe, komwe kumatha kugwiritsidwa ntchito popanga zinthu zama mankhwala monga zonunkhira, mapulasitiki, ndi utoto.

- Itha kugwiritsidwanso ntchito ngati zosungunulira m'mafakitale monga zokutira, inki, zomatira, etc.

- Ethyl allyl itha kugwiritsidwanso ntchito popanga utomoni, mafuta opaka mafuta ndi mapulasitiki.

 

Njira:

- Ethyl allyl nthawi zambiri imapangidwa ndi momwe ethylene ndi acrylic acid, yomwe imasinthidwa kukhala ethyl allylate.

- M'makampani, zopangira monga sulfuric acid nthawi zambiri zimagwiritsidwa ntchito kuti zithandizire.

 

Zambiri Zachitetezo:

- Ethyl allyl ndi madzi oyaka moto ndipo sayenera kukhudzana ndi malawi otseguka, kutentha kwambiri, ndi oxidizing agents.

- Valani zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zovala zodzitetezera mukamagwiritsa ntchito.

- Pewani kukhudzana ndi khungu, maso ndi kupuma kwa ethyl allylenate, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupita kuchipatala ngati zitero.

- Mikhalidwe yabwino yolowera mpweya iyenera kutengedwa mukasunga ndikugwiritsa ntchito ethyl allylenate.

- Potaya zinyalala, tsatirani malamulo oyendetsera chilengedwe.
