alpha-pentylcinnamaldehyde - Uses and synthesis methods
content analysis
as determined by method 1 in ester determination method (OT-18). The sample quantity is 1.3g, and the equivalent factor (e) in the calculation is 109.1. Or as determined by GT-10-4 non-polar column method.
content analysis
method 1 accurately weigh about 1.5g of sample, and then determine according to method 1 in aldehyde positive ketone determination method (OT-7). The equivalent factor in the calculation (e takes 101.2.
method 2 was determined by gas chromatography (GT-10-4) with polar column.
Toxicity
LD503730mg/kg (rat, oral).
use limited
FEMA(mg/kg): soft drink 1.3; Cold drink 1.5; Candy 4.0; Baked food 4.5; Pudding 0.03~0.05;
Production method
in alkaline ethanol solution, heptanal and benzaldehyde are condensed to methyl pentyl cinnamaldehyde: 8kg of 85% KOH solution is dissolved in 50kg of 95% ethanol for later use. 100kg of benzaldehyde, 15kg of the above-mentioned potassium hydroxide solution and 1 50kg of ethanol are added to the reaction kettle, stirred and heated at 25~28 ℃ while 63kg of heptanal and 43kg of potassium hydroxide ethanol solution are added dropwise, after 6h, stirring is continued for 2h, the reaction ends when the refractive index is above n D20 1.549 after sampling and washing off ethanol. After neutralization of the reactants, ethanol is first recovered by atmospheric distillation, cooled to 100 ℃, washed with water for 2-3 times, and left to separate the water layer to obtain crude products. Decompression fractionation recovers unreacted benzaldehyde, and then collects the fraction at 153~154 ℃(1333Pa) as the finished product.
