As an excellent bright agent for non-cyanide zinc plating DE additive, it can improve the anodic polarization over a wide current range, get bright coating, to create favorable conditions for environmental protection. Anti-microbial drugs cefadroxil benzyl penicillin derived from anisaldehyde in the pharmaceutical industry for the manufacture is an intermediate of antihistamine drugs.
        It can be used for the preparation and organic synthesis of perfume.

        Content Analysis

        0.8g of anisaldehyde is accurately weighed, and determined according to the method of aldehyde and ketone determination (OT-7) or the method of determination of two or aldehyde (OT-6).The time of the reactional placement for samples and control samples are 1.5 minutes respectively. Calculation of the equivalent factor (E) is to take 68.08. Or it can be measured by gas chromatography (GT-10-4) nonpolar column method.

        Toxicity

        ADI 1mg/kg(CE). LD50 1510 mg/kg(Rat, Oral). No evident abnormal showed in the process of growth, blood, tissues from rats which were either raised by feeds containing 1000 mg/kg anise aldehyde for 27~28 weeks or raised by feeds containing 10000 mg/kg anise aldehyde for 15 weeks.

        FEMA limits

        FEMA (mg/kg): Soft drinks 6.3; cold drink 5.6; candy 14; baked goods 16; puddings class from 0.5 to 30; gum from 18 to 76.Moderate limit(FDA§172.515,2000).The concentration of the final product is generally 5~30mg/kg.

        Production method

        It can be obtained through p-cresol methyl ether from the p-cresol by methylation and then oxidation by adding manganese dioxide and sulfuric acid. Or it is derived from the oxidation of anisole.
        Anise aldehyde is mainly included in anise oil, fennel oil, dill oil, gold Albizia julibrissin oil, vanilla extract, etc. When extracted from natural raw materials, it is oxidated by ozone, nitric acid, potassium permanganate, sodium dichromate or sulfuric acid, in the presence of p-Aminobenzene Sulfonic. It can also be obtained as follows: Anethole is Isolated from the essential oil, then decomposed by yellow blood salt, water, sodium bisulfite and other appropriate decomposing agent, cutting off the allyl double bond and generating anise aldehyde. According to the method, the yield was 60%. It had been discovered and synthesized before it has been isolated from the essential oil. The product can be prepared to take from phenol and anisole, cresol ether, preparation of p-hydroxybenzaldehyde and other raw materials. Using dimethyl sulfate for methylation of phenol, followed by chloromethylation reaction Fennel introducing chloromethyl ether and Urotropine with salt, and then hydrolyzed to chloromethyl into aldehyde (Suo Mulai reaction) to prepare p-methoxy benzaldehyde. Another promising approach is to turn on the methylation of toluene, the formation of methyl phenyl ether, and then oxidation to obtain the production. In foreign countries, the current method is using oxidating p-methyl anisole in sulfuric acid in the presence of the oxidizing agent such as potassium dichromate, potassium permanganate and manganese dioxide.

        Description

        p-Methoxybenzaldehyde has a characteristic hawthorne odor and a pungent, anise-like flavor. It has a bitter flavor above 30 - 40 ppm. May be prepared by methylation and oxidation of p-cresol and also by oxidation of anethole.

        Chemical Properties

        p-Methoxybenzaldehyde has a sweet, floral odor and a pungent, anise-like flavor. It has a bitter flavor above 30 to 40 ppm.

        Chemical Properties

        clear colorless to pale yellowish liquid

        Chemical Properties

        p-Anisaldehyde occurs in many essential oils, often together with anethole. It is a colorless to slightly yellowish liquid with a sweet, mimosa, hawthorn odor. p-Anisaldehyde can be hydrogenated to anise alcohol and readily oxidizes to anisic acid when exposed to air. Synthetic routes to anisaldehyde start from p-cresyl methyl ether, which is oxidized, for example, by manganese dioxide or by oxygen or peroxy compounds in the presence of transition metal catalysts .
        Another industrial process uses electrochemical oxidation in the presence of lower aliphatic alcohols via the corresponding anisaldehyde dialkyl acetal . Anisaldehyde may also be produced by methylation of 4-hydroxybenzaldehyde, which is easily obtained by oxidation of p-cresol or by Vilsmeier formylation of anisol.

        Occurrence

        Reported found in essential oils and extracts of vanilla, Acacia farmesiana Willd., Magnoila salicifolia Maxim., Erica arborea, Pirus communis, Boswellia serrata, and others; also in anise, fennel and star anise (especially when aged due to the oxidation of anethole), cranberry, black currant, cinnamon and basil.

        Uses

        Perfumery and toilet soaps; odor resembles that of coumarin, but the aldehyde must be mixed with other odorous substances to yield an agreeable odor. Also used in organic syntheses.

        Uses

        p-Anisaldehyde is a flavoring agent that is a colorless or faintly yellow liquid, hawthorn-like odor. It is miscible in alcohol, ether, and most fixed oils, soluble in propylene glycol, insoluble in glycerin, water, and mineral oil. It is obtained by synthesis. It is also termed anise aldehyde and p-methoxybenzaldehyde.

        Preparation

        By methylation and oxidation of p-cresol and also by oxidation of anethole.

        Aroma threshold values

        Aroma characteristics at 1.0%: sweet powdery, spicy creamy, fruity, vanilla and hay-like. Coumarin, almond, anisic with berry nuances.

        Taste threshold values

        Taste characteristics at 5 to 10 ppm: sweet powdery, vanilla creamy, spice anise, nutty, cherry pit and almond-like nuances.

        Safety Profile

        Moderately toxic by ingestion. A skin irritant. Mutation data reported. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes

        Metabolism

        Anisic aldehyde undergoes a very slight degree of demethylation with oxidation of its aldehyde group to an acid group, the major metabolite excreted being anisic acid (Williams, 1959).

        Purification Methods

        Wash the aldehyde with saturated aqueous NaHCO3, then H2O, steam distil, extract the distillate with Et2O, dry (MgSO4) the extract, filter and distil this under a vacuum and N2. Store it in glass ampules under N2 in the dark. [Beilstein 8 IV 252.]
