Mawu Oyamba
Salicylaldehyde ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha salicylaldehyde:
Ubwino:
- Maonekedwe: Salicylaldehyde ndi madzi opanda mtundu mpaka achikasu okhala ndi fungo lapadera la amondi.
- Kusungunuka: Salicylaldehyde imakhala ndi kusungunuka kwakukulu m'madzi ndipo imasungunukanso muzosungunulira zambiri.
Gwiritsani ntchito:
- Kununkhira ndi kununkhira: Salicylaldehyde ili ndi fungo lapadera la amondi ndipo imagwiritsidwa ntchito kwambiri mumafuta onunkhira, sopo ndi fodya ngati chimodzi mwazinthu zopangira fungo.
Njira:
- Nthawi zambiri, salicylaldehyde imatha kupangidwa kuchokera ku salicylic acid kudzera muzochita za redox. Chomwe chimagwiritsidwa ntchito kwambiri ndi yankho la acidic potassium permanganate.
- Njira ina yokonzekera ndi kupeza salicylyl mowa ester ndi chlorination ester wa phenol ndi chloroform catalyzed ndi hydrochloric acid, ndiyeno kupeza salicylyldehyde ndi hydrolysis reaction catalyzed ndi acid.
Zambiri Zachitetezo:
- Salicylaldehyde ndi mankhwala owopsa ndipo sayenera kukhudzana mwachindunji ndi khungu ndi maso.
- Mukamagwiritsa ntchito kapena kugwira salicylaldehyde, sungani mpweya wabwino ndikupewa kutulutsa nthunzi yake.
- Posunga salicylaldehyde, iyenera kusungidwa mu chidebe chopanda mpweya, kutali ndi kuyatsa ndi okosijeni.
- Ngati salicylaldehyde yalowetsedwa kapena kulowetsedwa molakwika, funsani thandizo lachipatala mwamsanga.
