chemical properties yellow oily liquid. soluble in acetone.

use gb 2760 a 1996 provisions for the use of food spices. mainly for the preparation of jasmine, apples, apricots, peaches, strawberries, walnuts and spices and other fragrances.

use gb 2760--1996 provides for the use of food spices. mainly used for the preparation of vanilla and chocolate flavor.

use is a widely used important spices, and phenylethanol with comparable jasmine ketone for a variety of floral formula, especially jasmine, lily of the valley, lilac and so on. in the soap with the essence of the general dosage of 2% -10%. also can be used as edible spices, trace for apples, apricots, peaches, strawberries, walnuts and aroma and other flavor.

uses are widely used in various types of fragrance, the deployment of jasmine, lily of the valley, lilac, etc., in the soap with the usual amount of 2 to 10%, in special circumstances up to 30 to 35%. instead of or part of the replacement of methyl hexyl cinnamaldehyde for low-grade soap with detergent fragrance can be more sudden floral.

use α-amyl cinnamaldehyde is a permissible use of our food spices, can be used to prepare apples, apricots, peaches, strawberries and other food flavor. consumption in the normal production needs, generally in the chewing gum 15mg / kg; baking food 4.5mg / kg; candy 4.0mg / kg; cold drink 1.5mg / kg; soft drinks 1.3mg / kg.

use as an important ingredient in jasmine flavor, but also for lilac, hyacinth and other spices and soap spices

production method in alkaline ethanol solution, heptaldehyde and benzaldehyde are condensed into methyl permethylethylaldehyde: 8kg of 85% koh solution is dissolved in 50kg of 95% ethanol. 100 kg of benzaldehyde, 15 kg of potassium hydroxide solution and 50 kg of ethanol were added to the reaction kettle. the mixture was heated and maintained at 25 to 28 ° c while 43 kg of heptaldehyde and 43 kg of potassium hydroxide were added dropwise. after 6 h, the mixture was stirred for 2 hours, after washing the ethanol after the refractive index in the n d20 1.549 above the end of the reaction. the reaction is neutralized and the ethanol is recovered by distillation at atmospheric pressure. after cooling at 100 ° c, the mixture is washed twice for 3 to 3 times. the unreacted benzaldehyde is recovered by decompression and fractionation. 154 ℃ (1333pa) of the distillate is the finished product.

production method in the presence of alkali conditions, dry distillation castor oil obtained by the aldehyde and benzaldehyde condensation derived. with an aldehyde rate of 80%. in the production conditions, the production of benzaldehyde aldehyde, is to the alkaline solution of methanol to add benzaldehyde, and at about 32 ℃ when the gradual addition of heptaldehyde reaction, until the washing sample after the refraction rate of 1.545 so far. and then add water to the condensation product, separation of alkali methanol water, from which the recovery of methanol. the crude vegetable aldehyde is washed with a salt solution and vacuum distilled to obtain the finished product. suin aldehyde in the air easily oxidized to produce benzoic acid, acetic acid and cinnamic acid. in the air can spontaneous combustion. and sometimes add 0.5% of its amount of diphenylamine as a stabilizer.

production methods from cinnamic acid and amyl alcohol esterification.

production methods benzaldehyde and n-heptaldehyde dissolved in dilute ethanol, sodium hydroxide in the room temperature for two days, the oil was acidified by acetic acid, extracted with ether, dried and then decompression fraction derived.
