methyl pent-4-ynoate (CAS # 21565-82-2)
Mawu Oyamba
methyl pent-4-ynoate ndi organic pawiri ndi mankhwala chilinganizo C7H10O2. Zotsatirazi ndizofotokozera za chikhalidwe chake, kagwiritsidwe ntchito, kapangidwe ndi chitetezo:
Chilengedwe:
-Maonekedwe: methyl pent-4-ynoate ndi madzi opanda mtundu;
-Kusungunuka: Kusungunuka mu zosungunulira za organic monga ethanol ndi ether, zovuta kusungunuka m'madzi;
-Kuwira: malo ake otentha ndi pafupifupi 142-144 ℃;
-Kachulukidwe: Kachulukidwe ake ndi pafupifupi 0.95-0.97g/cm³.
Gwiritsani ntchito:
-Chemical kaphatikizidwe: methyl pent-4-ynoate nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe ka organic ndipo angagwiritsidwe ntchito popanga zinthu zina za organic;
-Msika wa zokometsera ndi zonunkhiritsa: Umakhala ndi fungo lonunkhira ndipo utha kugwiritsidwa ntchito pokonza zakudya zokometsera ndi zonunkhiritsa.
Njira:
methyl pent-4-ynoate ikhoza kukonzedwa ndi njira zotsatirazi:
-Etherification reaction: pent-1-yne ndi methanol ndi esterified pamaso pa chothandizira kupanga methyl pent-4-ynoate.
Zambiri Zachitetezo:
methyl pent-4-ynoate iyenera kulabadira zambiri zachitetezo izi mukamagwiritsa ntchito ndikusunga:
-poizoni: methyl pent-4-ynoate ndi organic pawiri, amene angakhale ndi poizoni wina m'thupi la munthu. Mukamagwiritsa ntchito, pewani kukhudza khungu ndi maso, ndipo pewani kutulutsa mpweya wake;
-moto: methyl pent-4-ynoate ndi madzi oyaka moto, sayenera kukhudzana ndi moto wotseguka ndi kutentha kwakukulu, kusungirako kuyenera kusungidwa kutali ndi moto.
Chonde dziwani kuti machitidwe oyenera a labotale ndi njira zotetezera ziyenera kutsatiridwa mukamagwiritsa ntchito ndikugwiritsa ntchito mankhwala, ndipo akatswiri oyenerera ayenera kufunsidwa kuti adziwe zambiri zachitetezo.
