Mawu Oyamba
Triacetaldehyde. Zotsatirazi ndizofotokozera mwachidule za chikhalidwe chake, ntchito, njira yopangira ndi chitetezo.
Ubwino:
Acetaldehyde ndi ufa wopanda mtundu mpaka wotumbululuka wachikasu wokhala ndi kukoma kokoma.
Kulemera kwake kwa ma molekyulu ndi pafupifupi 219.27 g/mol.
Pa kutentha kwa firiji, triacetaldehyde imasungunuka m'madzi, methanol, ethanol ndi zosungunulira za ether. Idzawola pakatentha kwambiri.
Gwiritsani ntchito:
Acetaldehyde itha kugwiritsidwanso ntchito pokonza zida zamagetsi, zosinthira utomoni, zobwezeretsanso fiber flame ndi magawo ena ogulitsa.
Njira:
Acetaldehyde imatha kupezeka ndi acid-catalyzed polymerization ya acetaldehyde. Njira yeniyeni yokonzekera ndizovuta, zomwe zimafuna zinthu zina zoyesera ndi zopangira, ndipo nthawi zambiri zimafuna kuchitapo kanthu pa 100-110 ° C.
Zambiri Zachitetezo:
Acetaldehyde ikhoza kukhala yapoizoni komanso yokwiyitsa thupi la munthu pamlingo wina, ndipo chisamaliro chiyenera kutengedwa kuti musakhudze khungu, maso ndi kupuma mukamagwiritsa ntchito.
Mukakumana ndi gwero lamoto, polyacetaldehyde imatha kuyaka ndipo iyenera kusungidwa kutali ndi malawi otseguka komanso kutentha kwambiri.
Mukamagwiritsa ntchito kapena kusunga triacetaldehyde, malo olowera mpweya wabwino ayenera kusamalidwa komanso kutali ndi oxidizing agents.
Pogwira ntchito ya meretaldehyde, valani zida zodzitetezera zoyenera monga magolovesi, magalasi oteteza, ndi zophimba nkhope.
