5-chloropen-1-yne (CAS# 14267-92-6) chiyambi
5-Chloro-1-pentyne (yomwe imadziwikanso kuti chloroacetylene) ndi organic pawiri. Nawa chidule cha zomwe zili, ntchito, njira zopangira, ndi chidziwitso chachitetezo:
chilengedwe:
1. Maonekedwe: 5-Chloro-1-Pentyne ndi madzi opanda mtundu.
2. Kachulukidwe: Kachulukidwe ake ndi 0.963 g/mL.
4. Kusungunuka: 5-Chloro-1-Pentyne ndi yosasungunuka m'madzi ndipo imakhala yabwino kusungunuka muzosungunulira organic monga ethanol ndi dichloromethane.
Cholinga:
5-Chloro-1-pentyne imagwiritsidwa ntchito makamaka ngati poyambira komanso apakatikati pakupanga organic.
2. Ikhoza kugwiritsidwa ntchito pokonzekera mankhwala monga vinyl chloride, chloroalcohols, carboxylic acids, ndi aldehydes.
Njira yopanga:
5-Chloro-1-Pentyne ikhoza kukonzedwa ndi izi:
1. Sungunulani 1-pentanol mu sulfuric acid ndi kuwonjezera sodium kolorayidi.
2. Pang'onopang'ono onjezerani sulfuric acid dropwise ku yankho pa kutentha kochepa.
3. Kutenthetsa zomwe zimasakanikirana ndi kutentha koyenera pansi pa chikhalidwe chowonjezera sulfuric acid.
4. Kukonzekera kwina ndi kuyeretsedwa kwa zomwe zimapangidwira zimatha kutulutsa 5-chloro-1-pentyne.
Zambiri zachitetezo:
1. 5-Chloro-1-Pentyne ndi chigawo chomwe chimakwiyitsa komanso choyaka, ndipo njira zotetezera ziyenera kuchitidwa panthawi ya ntchito.
Mukamagwiritsa ntchito 5-chloro-1-pentyne, zida zoyenera zodzitetezera monga magolovesi oteteza, magalasi, ndi zovala zodzitchinjiriza ziyenera kuvala.
3. 5-Chloro-1-Pentyne iyenera kuyendetsedwa pamalo olowera mpweya wabwino kuti asatengeke ndi nthunzi komanso kukhudzana ndi malawi otseguka kapena magwero otentha.
4. Zinyalala ziyenera kutayidwa moyenera motsatira malamulo oyenerera ndipo zisatayidwe m'magwero a madzi kapena chilengedwe.
