Mawu Oyamba

Acetal diethanol.

 

Katundu: Acetal diethanol ndi madzi opanda mtundu mpaka kuwala achikasu omwe ali ndi mpweya wochepa. Amasungunuka m'madzi, ma alcohols, ndi zosungunulira za ether ndipo ndi pawiri yokhala ndi kukhazikika kwabwino.

 

Ntchito: Acetal diethanol ili ndi kusungunuka kwabwino kwambiri, pulasitiki komanso kunyowetsa katundu. Nthawi zambiri amagwiritsidwa ntchito ngati zosungunulira, zonyowetsa ndi mafuta.

 

Njira yokonzekera: acetal diethanol nthawi zambiri imakonzedwa ndi epoxy pawiri cyclization reaction. Ethylene oxide imayendetsedwa ndi mowa kuti ipeze ethyl alcohol diethyl ether, yomwe imapangidwa ndi acid-catalyzed hydrolysis kuti ipange acetal diethanol.

 

Chidziwitso chachitetezo: Acetal diethanol ndi mankhwala otsika kawopsedwe, komabe ndikofunikira kusamala kugwiritsa ntchito moyenera. Pewani kukhudzana ndi ma okosijeni amphamvu, ma asidi amphamvu ndi ma okosijeni kuti mupewe kuwonongeka kwa mankhwala kapena ngozi zowopsa. Magolovesi otetezera oyenerera, magalasi, ndi maovololo ayenera kuvala pakagwiritsidwa ntchito.
