Ibisobanuro

imigozi lauraldehyde, izwi kandi nka doylaldehyde, idafite ibara ryuzuye kandi rifite amavuta meza cyangwa ibibabi bisa na kirisiti, bigahinduka okiside ikora aside ya lauric. Kamere ibaho mumavuta yingenzi nkamavuta yindimu, amavuta yindimu namavuta ya rue.
Porogaramu lauraldehyde ifite uburyohe bwa aldehyde hamwe namavuta. Hamwe n'indabyo nziza na citrus. Irashobora gukoreshwa muke muburyohe bwindabyo burimunsi nka lili yikibaya, indabyo za orange, violet, nibindi. Muburyohe buribwa, igitoki, citrusi, imbuto zivanze nizindi mbuto zimbuto zirashobora gutegurwa.
isesengura ry'ibirimo byagenwe nuburyo butari inkingi muburyo bwa gazi chromatografiya (GT-10-4).
uburozi ADI 1 mg / kg ((3E)). LD50 23000 mg / kg (imbeba, umunwa).
imipaka ikoreshwa FEMA (mg / kg): ibinyobwa bidasembuye 0,93; Ibinyobwa bikonje 1.5; Candy 2.4; Ibiryo bitetse 2.8; Pudding 0.10; Gum bombo 0,20 ~ 110. Imipaka ntarengwa (FDA 172.515.2000).
Koresha GB 2760-1996 iteganya ko byemewe by'agateganyo gukoresha ibirungo biribwa. Ahanini bikoreshwa mugutegura amavuta, karamel, ubuki, ibitoki, indimu nizindi citrus hamwe nimbuto zivanze.
Dylaldehyde ni intera n'ibirungo muri synthesis. Iyo ivanze, iba ifite impumuro nziza kandi ndende nka violet, ishobora gukoreshwa muri jasimine, ukwezi, ukwezi kwa lili yo mubande hamwe na flavour flavours.
Uburyo bwo gukora Itegurwa na okiside ya decanediol no kugabanya aside dodecanoic. Kugabanya aside ya dodecyl kuri dodecyl aldehyde ikorwa kuri 250-330 ° C imbere ya aside irike na methanol. Igicuruzwa cyo kugabanya gitandukanijwe namazi ya aside, kwozwa namazi, na dodecylaldehyde itandukanijwe no kugabanya umuvuduko ukabije. Kugabanya reaction bisaba titanium dioxyde cyangwa karubone ya manganese nka catalizator. Carbonate ya Manganese iboneka mugukora aside sulfurike na karubone ya sodium.
Ihindurwa na alcool ya lauryl. Cyangwa aside ya lauric yagabanutse.
