Introduction | hexyl acetate natural products are found in apples and strawberry, colorless, transparent, oily liquid, with pear and apple-like aroma, it has a pear-like sour and sweet taste. Is China's GB2760-1996 regulations allow the use of edible spices, modulation of pear, apple and other fruit flavor; Also used as cosmetics spices; Organic synthesis intermediates. Hexyl acetate is recognized by FEMA as GRAS,FEMA No. 2565 and is approved by the FDA for use in food, and the European Council also lists it in the list of artificial flavors that can be used in food and are not harmful to human health, daily tolerable ADI value was 1 mg/kg. Hexyl acetate may be used in food flavor formulations. |
assay | was determined by method one in the ester determination method (OT-18). The amount of the sample was 1.1g. The equivalence factor (e) in the calculation is taken as 72.10. Or according to the GT-10-4 gas chromatography non-polar column method. |
toxicity | GRAS(FEMA). LD50 42g/kg (rat, oral). |
usage limit | FEMA(mg/kg): Soft drink 4.6; Cold drink 4.6; Candy 26; Baked goods 26; gum 3.0. Moderate limits (FDA § 172.515,2000). |
Use | hexyl acetate has fruit flavor and is used in the consumption of fruit flavor. It is also used in organic synthesis. GB 2760-96 provides for the permitted use of flavorants. Mainly used for the preparation of apple, pear and other fruit flavor; Ethyl acetate with fruit flavor, used in edible fruit flavor, also used in organic synthesis. |
production method | is obtained by esterification of acetic acid and hexanol. 23kg of N-hexanol, 15kg of acetic acid, 18kg of benzene and 250g of sulfuric acid were added to a glass-lined reaction pan. The mixture was heated to reflux slowly, and benzene was separated by condensation in an oil-water separator and refluxed into a reaction pan. After about 2H, when the refluxing benzene is clear, the moisture has been removed. The benzene was distilled off and recycled. The residue was crude and washed several times with 5% sodium carbonate solution and then with water. After drying with anhydrous potassium carbonate, Fractionation was carried out, and the 170-173 ° C. Fraction was collected to obtain a finished product. obtained by boiling reaction of N-hexanol with excess acetic anhydride (or with excess acetic acid in the presence of concentrated sulfuric acid). |
