Mawu Oyamba
Acetone aldehyde dimethanol, yomwe imadziwikanso kuti acetone methanol. Zotsatirazi ndikuwulula za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha acetone aldehyde dimethanol:
Ubwino:
Acetone aldehyde dimethanol ndi madzi opanda mtundu mpaka chikasu ndi fungo loipa. Ndi mankhwala omwe amasungunuka m'madzi, ma alcohols, ndi ethers. Acetone aldoldehyde methanol ndi yosakhazikika, imapangidwa mosavuta ndi hydrolyzed komanso okosijeni, imayenera kusungidwa pamalo ozizira komanso amdima, ndikusungidwa kutali ndi mpweya, kutentha ndi kuyatsa.
Gwiritsani ntchito:
Acetone aldoldehyde dimethanol nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe ka organic. Itha kugwiritsidwa ntchito pokonza ma esters, ethers, amides, ma polima, ndi zinthu zina za organic. Pyrudaldehyde methanol imagwiritsidwanso ntchito ngati zosungunulira, zonyowetsa komanso zowonjezera m'mafakitale okutira ndi mapulasitiki.
Njira:
Pali njira zingapo zopangira acetone aldehyde dimethanol. Njira yodziwika bwino imapezedwa ndi condensation reaction ya methanol ndi acetone. Pokonzekera, methanol ndi acetone zimasakanizidwa pamlingo wina wa molar ndipo zimachita pamaso pa chothandizira cha acidic, chomwe nthawi zambiri chimafunikira kutenthetsa kusakaniza. Zomwezo zikamalizidwa, acetone aldoldehyde dimethanol yoyera imapezedwa ndi distillation, crystallization kapena njira zina zolekanitsa.
Zambiri Zachitetezo:
Acetone aldoldemic methanol ndi chinthu chokwiyitsa ndipo chiyenera kupewedwa pokhudzana ndi khungu, maso, ndi mucous nembanemba. Mpweya wabwino uyenera kuchitika panthawi yogwira ntchito, ndipo magolovesi oteteza ndi magalasi ayenera kuvala. Pogwira ndi kusunga, chidebecho chiyenera kutsekedwa bwino ndi kutentha, kuyatsa ndi okosijeni. Mukalowetsedwa kapena kupumira, pitani kuchipatala mwamsanga.
