Mawu Oyamba
pent-4-ynoic acid, yomwe imadziwikanso kuti pent-4-ynoic acid, formula yamankhwala C5H6O2. Zotsatirazi ndizofotokozera za chilengedwe, kugwiritsa ntchito, kupanga ndi chitetezo cha pent-4-ynoic acid:
Chilengedwe:
- pent-4-ynoic acid ndi madzi opanda mtundu okhala ndi fungo lamphamvu.
-Kulemera kwake kwa maselo ndi 102.1g / mol.
Gwiritsani ntchito:
- pent-4-ynoic acid ndi yofunika kwambiri pakatikati pakupanga mankhwala ndipo imagwiritsidwa ntchito pokonzekera mankhwala ena.
- Itha kugwiritsidwa ntchito ngati carbonylation reaction, condensation reaction ndi esterification reaction mu organic synthesis reaction.
- pent-4-ynoic acid angagwiritsidwenso ntchito pokonza mankhwala, zonunkhira ndi utoto.
Njira Yokonzekera:
-Kukonzekera kwa pent-4-ynoic acid chingapezeke ndi 1-chloropentyne ndi asidi hydrolysis. Choyamba, 1-chloropentyne imayendetsedwa ndi madzi kuti ipereke aldehyde kapena ketone yofananira, kenako aldehyde kapena ketone imasinthidwa kukhala pent-4-ynoic acid ndi oxidation reaction.
Zambiri Zachitetezo:
- pent-4-ynoic acid ndi mankhwala opweteka omwe angayambitse kupsa mtima ndi kutupa pokhudzana ndi khungu ndi maso.
-Valani magolovesi oteteza, magalasi, ndi zovala za labotale mukamagwiritsa ntchito pent-4-ynoic acid.
-Mukakhudza khungu kapena maso, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupita kuchipatala.
- Pewani kukhudzana ndi ma oxidants, ma acid amphamvu ndi maziko amphamvu posungira ndikugwiritsa ntchito kupewa zoopsa.
Chonde dziwani kuti musanagwiritse ntchito mankhwala aliwonse, muyenera kuwerenga pepala lachitetezo (MSDS) la mankhwalawo mosamala ndikutsata njira zolondola zogwirira ntchito komanso njira zotetezeka.
