Benzaldehyde Usage And Synthesis

Uses		1. Benzaldehyde is an important raw material for medicine, dyestuff, perfume and resin industry. It also can be used as solvent, plasticizer and low temperature lubricant. In essence, it is mainly used for the deployment of food flavor. A small amount of benzaldehyde is daily use in flavor and flavor of tobacco. In spite of being widely used as commercial food condiment and industrial solvents, the main use of benzyl alcohol is still used to synthesize a variety of other compounds from pharmaceuticals to plastic additives. Benzyl alcohol is an important intermediate product in the production of perfumes, spices, and some aniline dyes. Mandelic acid was synthesized by benzaldehyde as the starting reagent: With the first hydrocyanic acid reacts with benzaldehyde, then mandelonitrile hydrolyzed to Racemic mandelic acid. Glacialist LaChepelle and Stillman reported Ice crystallization is inhibited by benzaldehyde and aldehydes ice in 1966, so as to prevent the thick frost formation (Depth Hoar). This process can prevent snowslide caused by the instability of the snow cover. However, this compound has not been used extensively, because of the destruction of vegetation and polluted water sources. 2.It is mainly used for the preparation of flavors, such as almond, cherry, peach, nuts, etc., the amount is up to 40%. As aromatizing agent canned cherry syrup, adding amount is sugar 3mL/kg. 3. Pharmaceutical, dyestuff, spice intermediates. For the production of oxygen based benzene formaldehyde, lauric acid, lauric aldehyde, malachite, benzyl benzoate, benzyl aniline and benzylidene acetone etc.. Used to tune the soap flavor, edible essence, etc. 4. As the head of the special aroma, it is used trace formula for fragrance, such as lilac, white, violet, jasmine, acacia, sunflower, sweet plum, orange flower, Tofu pudding etc.. Also it is used in soap. Also it can be used as edible spices for almond, coconut cream, berries, cherries, apricots, peaches, plums, walnuts, and vanilla bean, spicy flavor. Wine with flavors such as rum, brandy, etc. 5. Benzaldehyde is an intermediate of herbicide resistance, plant growth regulator, and anti-amine. 6. Used as a reagent for the determination of ozone, phenol, alkaloid and methylene. Used in the preparation of spices.
Air & Water Reactions	Oxidizes in air to form benzoic acid, which is moderately toxic by ingestion. Insoluble in water.
storage			Benzaldehyde should be kept stored in a tightly closed container and protected against physical damage. Storage of the chemical substance outside or in a detached area is preferred, whereas inside storage should be in a standard flammable liquids storage room or cabinet. Benzaldehyde should be kept separated from oxidizing materials. Also, storage and use areas should be no smoking areas. Containers of this material may be hazardous when empty since they retain product residues (vapors, liquid); observe all warnings and precautions listed for the product

Benzaldehyde is an organic compound with a molecular formula of C7H6O, a colorless liquid. It is found in hyacinth, lemongrass, cinnamon, iris, and cistus. It has bitter almond, cherry and nut aromas.

Benzaldehyde is the simplest and the most commonly used aromatic aldehyde in industry. It is a colorless liquid at room temperature with a special almond smell. Benzaldehyde is the main component of almond oil extract. It can also be extracted from apricots, cherries, bay leaves and peach pits. This compound is also present in nuts and nuts in the form of glycosides (mandelin).

The chemical properties of benzaldehyde are similar to fatty aldehydes, but there are also differences. Benzaldehyde cannot reduce Fehling's reagent; when reducing benzaldehyde with the reagent used when reducing fatty aldehydes, in addition to the main product benzyl alcohol, some tetra-substituted vicinal glycol compounds and s-diphenyl glycol are also produced. In the presence of potassium cyanide, two molecules of benzaldehyde generate benzoin by donating hydrogen atoms. Benzaldehyde can also undergo an electrophilic substitution reaction on the aromatic nucleus, which mainly produces meta-substituted products. For example, the main product during nitration is meta-nitrobenzaldehyde. It is easily oxidized in the air to produce white benzoic acid. It can react with amides to produce pharmaceutical intermediates.
