Gabatarwa
Acetone aldehyde dimethanol, wanda kuma aka sani da acetone methanol. Mai zuwa shine gabatarwa ga kaddarorin, amfani, hanyoyin shiri da bayanan aminci na acetone aldehyde dimethanol:
inganci:
Acetone aldehyde dimethanol ruwa ne mara launi zuwa rawaya tare da ƙamshi mai ƙamshi. Yana da kwayoyin halitta wanda ke narkewa a cikin ruwa, alcohols, da ethers. Acetone aldoldehyde methanol ba shi da kwanciyar hankali, cikin sauƙin ruwa da oxidized, yana buƙatar adana shi a wuri mai sanyi da duhu, kuma a nisanta shi daga iskar oxygen, zafi da tushen ƙonewa.
Amfani:
Acetone aldoldehyde dimethanol ana yawan amfani dashi azaman tsaka-tsaki a cikin haɗin kwayoyin halitta. Ana iya amfani da shi a cikin shirye-shiryen esters, ethers, amides, polymers, da wasu kwayoyin halitta. Pyrudaldehyde methanol kuma ana amfani dashi azaman kaushi, wakili mai jika da ƙari a cikin masana'antar sutura da robobi.
Hanya:
Akwai hanyoyi da yawa don shirya acetone aldehyde dimethanol. Ana samun hanyar gama gari ta hanyar haɓakar haɓakar methanol tare da acetone. A cikin shirye-shiryen, methanol da acetone suna haɗuwa a wani yanki na molar kuma suna amsawa a gaban mai haɓaka acidic, wanda yawanci yana buƙatar dumama cakudawar amsawa. Bayan an gama amsawa, ana samun tsantsar acetone aldoldehyde dimethanol ta hanyar distillation, crystallization ko wasu hanyoyin rabuwa.
Bayanin Tsaro:
Acetone aldoldemic methanol wani fili ne mai ban haushi kuma yakamata a guji shi cikin hulɗa kai tsaye tare da fata, idanu, da mucous membranes. Dole ne a gudanar da iskar iska mai kyau yayin aiki, kuma a sanya safar hannu da tabarau masu kariya. Lokacin sarrafawa da adanawa, ya kamata a rufe akwati da kyau daga zafi, ƙonewa da oxidants. Idan an sha ko an shaka, nemi kulawar likita nan da nan.
