Cov ntaub ntawv siv

roperties lauraldehyde, tseem hu ua doylaldehyde, yog xim tsis muaj xim thiab pob tshab oily kua los yog nplooj zoo li muaju, uas yog oxidized los tsim lauric acid. Xwm muaj nyob rau hauv cov roj yam tseem ceeb xws li txiv qaub roj, txiv qaub roj thiab rue roj.
daim ntawv thov lauraldehyde muaj qhov tsw ntawm aldehyde thiab roj. Nrog qab zib floral thiab citrus aromas. Nws tuaj yeem siv tau me me hauv cov paj ntoo txhua hnub xws li lily ntawm hav, txiv kab ntxwv paj, violet, thiab lwm yam. Ntawm cov khoom qab zib, txiv tsawb, citrus, cov txiv hmab txiv ntoo sib xyaw thiab lwm cov txiv hmab txiv ntoo flavors tuaj yeem npaj tau.
tsom xam cov ntsiab lus txiav txim los ntawm txoj kev tsis-polar kab hauv cov roj chromatography (GT-10-4).
tshuaj lom ADI 1 mg/kg ((3E)). LD50 23000 mg/kg (rat, oral).
kev siv txwv FEMA (mg / kg): dej qab zib 0.93; dej txias 1.5; Khoom qab zib 2.4; ci zaub mov 2.8; Pudding 0.10; Khoom qab zib 0.20 ~ 110. Tsawg txwv (FDA 172.515,2000).
siv GB 2760-1996 qhia tias nws raug tso cai ib ntus los siv cov txuj lom uas tau txais txiaj ntsig. Feem ntau yog siv los npaj cov qab zib, caramel, zib ntab, txiv tsawb, txiv qaub thiab lwm yam citrus thiab cov txiv hmab txiv ntoo sib xyaw.
Dylaldehyde yog ib qho nruab nrab thiab txuj lom hauv cov organic synthesis. Thaum diluted, nws muaj ib tug muaj zog thiab kav ntev aroma zoo li violet, uas yuav siv tau nyob rau hauv jasmine, moonshine, lily ntawm lub hav thiab violet flavors.
Txoj kev tsim khoom Nws yog npaj los ntawm oxidation ntawm decanediol thiab txo cov dodecanoic acid. Kev txo qis ntawm dodecyl acid rau dodecyl aldehyde yog nqa tawm ntawm 250-330 ° C nyob rau hauv muaj formic acid thiab methanol. Cov khoom txo yog sib cais los ntawm cov kua qaub, ntxuav nrog dej, thiab dodecylaldehyde yog cais los ntawm kev txo qis distillation. Kev txo cov tshuaj tiv thaiv yuav tsum tau titanium dioxide los yog manganese carbonate raws li catalyst. Manganese carbonate yog tau los ntawm cov tshuaj tiv thaiv ntawm sulfuric acid thiab sodium carbonate.
Nws yog oxidized los ntawm lauryl cawv. Los yog lauric acid txo.
