Abstract
A process for preparing natural benzaldehyde by hydrolyzing cinnamon leaf oil includes respectively atomizing the cinnamon leaf oil and the aqueous solution of alkaline substance while spraying them in reactor, reacting to generate benzaldehyde, and collecting benzaldehyde from the resultant. Its advantage is high output rate.
Description
Technical field
The present invention relates to a kind of preparation method of natural perfume, relate to a kind of preparation method of natural benzaldehyde specifically, more specifically say that relating to a kind of is raw material with the Bay leaves oil, hydrolysis prepares method of benzaldehyde.
Background technology
Along with the raising of people's living standard, people require the heart more and more higher to the healthy heart of food.Particularly the spices to adding in food is had higher requirement.People not only more and more pay attention to adopt various natural flavoring as foodstuff additive, and wish that the natural perfume that is adopted has higher quality and than the price at the end.Phenyl aldehyde is a kind of important spices that is used for food, has a wide range of applications at field of food.At present, a large amount of natural benzaldehydes derive from oil of bitter almond, but because therefore the prussiate separation difficulty that is contained in this oil has limited its application at field of food.Document [Guangxi chemical industry, 1997. the 3rd phase] reported a kind of preparation method of phenyl aldehyde, this method adopts the method for direct hydrolysis, extract with natural cinnamon--Bay leaves oil is a raw material, the preparation phenyl aldehyde, though this method has overcome some defective of prior art, its yield only is 39%, simultaneously in preparation process, add tensio-active agent, influenced the quality of product.Therefore, the suitability for industrialized production of this method still has certain difficulty, can not satisfy the demand of relevant department.
Summary of the invention
The technical issues that need to address of the present invention are to disclose the novel method that a kind of Bay leaves oil hydrolysis prepares natural benzaldehyde, to overcome the lower defective of yield that prior art exists.
Method of the present invention comprises the steps:
With the cinnamomic extract--the aqueous solution of Bay leaves oil and alkaline matter is respectively by spraying into reactor after the multi-channel nozzle atomizing, Bay leaves oil and alkaline matter are reacted under atomizing state, generate phenyl aldehyde, adopt conventional method from reaction product, to collect phenyl aldehyde then.
Preferred temperature of reaction is 100～110 ℃, and the reaction times is 0.5～1.5 hour.Adopt vapor-phase chromatography to analyze, the result shows that the yield of phenyl aldehyde can reach more than 45%, and the phenyl aldehyde that is obtained has happy almond fragrance, and fragrance is soft.
By above-mentioned disclosed technology as seen, method of the present invention has overcome the defective that prior art exists, and the yield height is convenient to large-scale industrial production.
Description of drawings
Fig. 1 is a process flow sheet of the present invention.
Embodiment
Referring to Fig. 1, method of the present invention comprises the steps:
With the cinnamomic extract--Bay leaves oil and alkaline substance solution are respectively by spraying into reactor 1 after multi-channel nozzle 2 atomizings that are arranged on reactor 1 top, Bay leaves oil and alkaline matter are reacted under atomizing state, generate phenyl aldehyde, the material of reactor 1 bottom is sent to the nozzle 2 at top by recycle pump 3, recycle, finish up to reaction, adopt conventional method from reaction product, to collect phenyl aldehyde then.
In optimized technical scheme of the present invention, the linear velocity of Bay leaves oil in nozzle 2 exits is 10～20 meter per seconds, and the linear velocity of alkaline substance solution in nozzle 2 exits is 50～300 meter per seconds.
Said alkaline matter can preferably adopt NaOH or Na
2CO
3And composition thereof, its consumption is 0.01～0.04% of a Bay leaves oil weight, preferably 0.02%.
Preferred temperature of reaction is 100～110 ℃, and the reaction times is 0.5～1.5 hour.
Adopt flow process shown in Figure 1.With Bay leaves oil and the NaOH aqueous solution respectively by spraying into reactor 1 after two channel nozzle, 2 atomizings that are arranged on reactor 1 top, Bay leaves oil and alkaline matter are reacted under atomizing state, generate phenyl aldehyde, the material of reactor 1 bottom is sent to the nozzle 2 at top by recycle pump 3, recycle, finish up to reaction, adopt conventional method from reaction product, to collect phenyl aldehyde then.
The linear velocity of Bay leaves oil in nozzle 2 exits is 15 meter per seconds, and the linear velocity of the NaOH aqueous solution in nozzle 2 exits is 50～300 meter per seconds.The NaOH consumption is 0.02% of a Bay leaves oil weight.
Preferred temperature of reaction is 100～110 ℃, and the reaction times is 0.5～1.5 hour.Yield is 45.5%.
