Zambiri Zolozera

katundu lauraldehyde, yomwe imadziwikanso kuti doylaldehyde, imakhala yopanda mtundu komanso yowoneka bwino yamafuta amadzimadzi kapena makristasi onga masamba, omwe amapangidwa ndi okosijeni kuti apange lauric acid. Chilengedwe chilipo mumafuta ofunikira monga mafuta a mandimu, mafuta a mandimu ndi mafuta a rue.
ntchito lauraldehyde ili ndi kukoma kwa aldehyde ndi mafuta. Ndi fungo lokoma lamaluwa ndi zipatso za citrus. Ikhoza kugwiritsidwa ntchito pang'onopang'ono mu zokometsera zamaluwa tsiku ndi tsiku monga kakombo wa m'chigwa, duwa la lalanje, violet, ndi zina zotero. Pakati pa zokometsera zodyera, nthochi, citrus, zipatso zosakanikirana ndi zokometsera zina za zipatso zimatha kukonzekera.
kusanthula kwazinthu kutsimikiziridwa ndi njira yopanda polar mu chromatography ya gasi (GT-10-4).
kawopsedwe ADI 1 mg/kg((3E)). LD50 23000 mg/kg (khoswe, pakamwa).
malire ogwiritsa ntchito FEMA(mg/kg): chakumwa choziziritsa kukhosi 0,93; Chakumwa chozizira 1.5; Maswiti 2.4; Zakudya zophikidwa 2.8; Pudding 0.10; Maswiti a Gum 0.20-110. Malire apakati (FDA 172.515,2000).
ntchito GB 2760-1996 ikunena kuti ndizololedwa kugwiritsa ntchito zonunkhira zodyedwa kwakanthawi. Amagwiritsidwa ntchito kwambiri pokonzekera kirimu, caramel, uchi, nthochi, mandimu ndi zipatso zina za citrus ndi osakaniza zipatso.
Dylaldehyde ndi yapakatikati komanso zokometsera mu organic synthesis. Ikachepetsedwa, imakhala ndi fungo lamphamvu komanso lokhalitsa ngati violet, lomwe lingagwiritsidwe ntchito mu jasmine, kuwala kwa mwezi, kakombo wakuchigwa ndi zokometsera za violet.
Njira yopangira Imakonzedwa ndi makutidwe ndi okosijeni wa decanediol ndi kuchepetsa dodecanoic acid. Kuchepetsa kwa dodecyl acid kukhala dodecyl aldehyde kumachitika pa 250-330 ° C pamaso pa formic acid ndi methanol. Chotsitsacho chimasiyanitsidwa ndi madzi a asidi, otsukidwa ndi madzi, ndipo dodecylaldehyde imasiyanitsidwa ndi kuchepetsedwa kwa distillation. Kuchepetsa kumafuna titaniyamu woipa kapena manganese carbonate ngati chothandizira. Manganese carbonate amatengedwa ndi zomwe sulfuric acid ndi sodium carbonate.
Amapangidwa ndi lauryl mowa. Kapena lauric acid yafupika.
