5-CYANO-1-PENTYNE (CAS# 14918-21-9)

chilengedwe
Acetylene nitrile wapangidwa. Ndi madzi opanda mtundu komanso onunkhira. Izi ndi zina mwazinthu zazikulu za acetylenic nitriles:

1. Kusungunuka: Nitrile imakhala ndi kusungunuka kochepa m'madzi, koma imatha kusungunuka muzitsulo zina monga ma alcohols, ethers, ketones, chlorinated hydrocarbons, ndi zina zotero.

2. Kukhazikika: Nitrile imakhala yokhazikika kutentha kwa firiji, koma imakhala ndi polymerization reaction ikatenthedwa. Itha kuchitapo kanthu ndi zinthu zomwe zili ndi magulu ogwira ntchito, monga ma alcohols, acids, ndi zina zambiri, kuti apange mitundu yosiyanasiyana.

3. Poizoni: Nitrile ali ndi kawopsedwe kena ndipo amatha kukwiyitsa khungu ndi mucous nembanemba. Kuwonekera kwa nthawi yayitali kapena kudya kwambiri kwa acetylenic nitriles kungayambitse ngozi zina.

4. Chemical reactions: Acetylene nitrile imatha kukumana ndi zochita zowonjezera, ma hydrogenation reaction, ma elekitironi owonjezera, ndi zina zambiri. Zomwe zimagwiritsidwa ntchito popanga zinthu zofunika kwambiri za organic monga ma ketoni, esters, ndi zina zambiri.

zambiri zachitetezo
Nitrile (wotchedwanso sera ya acetylene) ndi mankhwala. Zotsatirazi ndi chidziwitso cha chitetezo cha acetylene nitrile:

1. Poizoni: Nitrile ndi mankhwala oopsa omwe amatha kulowa m'thupi la munthu kudzera mu mpweya, kukhudza khungu, ndi kuyamwa. Zimakwiyitsa komanso zimawononga, ndipo zimatha kuwononga khungu, maso, kupuma, komanso kugaya chakudya.

2. Kukhudzana pakhungu: Nitrile imatha kuyambitsa kuyabwa pakhungu komanso kuyabwa.

3. Kuyang'ana m'maso: Kuwonetsedwa ndi acetylene kungayambitse kupsa mtima kwambiri ndi kuwonongeka. Mukakhudzana, muzimutsuka m'maso ndi madzi ambiri kwa mphindi zosachepera 15 ndipo pitani kuchipatala mwamsanga.

4. Zotsatira za dongosolo la kupuma: Kukoka mpweya wa acetylene kungayambitse kupuma, zilonda zapakhosi, chifuwa, kupuma movutikira, ndi chifuwa chomangika.

5. Njira zothandizira chithandizo choyamba: Ngati mupuma mpweya, kukhudza khungu, kapena kuyang'ana m'maso ndi acetylene nitrile, njira zothandizira mwamsanga ziyenera kuchitidwa ndipo chithandizo chamankhwala chiyenera kufunidwa mwamsanga.

6. Kasungidwe ndi Kagwiridwe: Nitrile iyenera kusungidwa pamalo amdima, otsekedwa, ndi mpweya wabwino. Iyenera kusungidwa mosiyana ndi ma okosijeni ndi ma asidi amphamvu. Pogwira acetylene nitrile, zida zodzitetezera monga magolovesi, magalasi, ndi zovala zodzitetezera ziyenera kuvala.
