The stoichiometric equation for the aldol condensation of benzaldehyde with acetone (CH32C o is given below. With that said, this page will provide you the benzaldehyde density in kg/m³ (SI unit), g/cm³, g/ml, kg/l, lb/gal. Still, subjecting cinnamaldehyde to the retro aldol reaction is undoubtably a chemical conversion into a distinctly separate chemical. Also 1.6 ml Acetone, density 0.79 g/ml.

[22] Benzaldehyde does not accumulate in human tissues. Industrially, the substance mainly serves as a precursor to the wide range of other organic compounds, from plastic additives to pharmaceuticals. ... 3.2.6 Density. On our website, you can order the top-quality products with fast worldwide delivery. A significant quantity of natural benzaldehyde is produced from cinnamaldehyde obtained from cassia oil by the retro-aldol reaction:[10] the cinnamaldehyde is heated in an aqueous/alcoholic solution between 90 °C and 150 °C with a base (most commonly sodium carbonate or bicarbonate) for 5 to 80 hours,[12] followed by distillation of the formed benzaldehyde. Get more help from Chegg. [8] In 1832, Friedrich Wöhler and Justus von Liebig first synthesized benzaldehyde. What's more, there is a simple way to produce the chemical in the lab.

(The scheme above depicts only one of the two formed enantiomers). It is a member of benzoins and a secondary alpha-hydroxy ketone. It should be kept in tightly sealed container in cool dry place, far from light and heat. [7] Further work on the oil by Pierre Robiquet and Antoine Boutron-Charlard, two French chemists, produced benzaldehyde. This is 0.22 mol. [14] This status was reaffirmed after a review in 2005. When food is cooked it is often altered by catalytic oxidation conditions in cooking that can even impart some amount of toxicity (however insignificant). It may also be used for determination of hydrazine Benzaldehyde CAS # 100-52-7. [17] It is metabolized and then excreted in urine. density 1.014 g/mL at 25 °C (lit.) Benzaldehyde (C6H5CHO) is an organic compound consisting of a benzene ring with a formyl substituent. It is a colorless liquid with a characteristic almond-like odor. This glycoside breaks up under enzyme catalysis into benzaldehyde, hydrogen cyanide and two equivalents of glucose. GC Mass Spectrum. Benzaldehyde has many uses. para-Dimethylaminobenzaldehyde is an organic compound containing amine and aldehyde moieties which is used in Ehrlich's reagent and Kovac's reagent to test for indoles.The carbonyl group typically reacts with the electron rich 2-position of the indole but may also react at the C-3 or N-1 positions. The density of benzaldehyde is 1.04 g/mL. [17] Toxicology studies indicate that it is safe and non-carcinogenic in the concentrations used for foods and cosmetics,[17] and may even have anti-carcinogenic (anti-cancer) properties. It is actually believed to be one of the most industrially useful aldehydes. Benzaldehyde can be oxidized to benzoic acid; in fact "[B]enzaldehyde readily undergoes autoxidation to form benzoic acid on exposure to air at room temperature"[16] causing a common impurity in laboratory samples. They put benzaldehyde solution on a fume board near the honeycombs to make bees to move away. The compound is considered stable under recommended storage conditions. ››Benzaldehyde molecular weight. 1.196 at 142 °F (NTP, 1992) National Toxicology Program, Institute of Environmental Health Sciences, National Institutes of Health (NTP). The chemical is very refractive. Via aldol condensations, benzaldehyde is converted into derivatives of cinnamaldehyde and styrene. Density of Benzaldehyde = 1.0449 g/cm³ The synthesis of mandelic acid starts with the addition of hydrocyanic acid to benzaldehyde: The resulting cyanohydrin is hydrolysed to mandelic acid. Its solubility in water is 3 g/L. However, the memoir was largely ignored until an extract was published in 1819: Martrès, CS1 maint: multiple names: authors list (, Brühne, Friedrich and Wright, Elaine (2002) “Benzaldehyde” in, Wienes, Charles and Pittet, Alan O. 13 346 0713 It has a role as an EC 3.1.1.1 (carboxylesterase) inhibitor.

[17], Except where otherwise noted, data are given for materials in their, Scott, Howard R. and Scott, Lillian E. (1920), In 1803 C. Martrès published a manuscript on the oil of bitter almonds: "Recherches sur la nature et le siège de l'amertume et de l'odeur des amandes amères" (Research on the nature and location of the bitterness and the smell of bitter almonds). [13], Benzaldehyde and similar chemicals occur naturally in many foods. MW 58.08 g/mol. [6], Benzaldehyde was first extracted in 1803 by the French pharmacist Martrès. Compound Structure and Properties. meta-Nitrobenzaldeh yde. Its solubility in water is 3 g/L. It is also a component of some acridine and aniline dyes, such as malachite green. The bees then move away from the honey combs to avoid the fumes. Prepare the raw material of benzaldehyde and then have the process of nitration under the existence of vitriol with nitrate of potash, sodium nitrate or hydrogen nitrate, then you could get the 3-Nitrobenzaldehyde, with the productivity of 80%、60% and 75%. [20], As used in food, cosmetics, pharmaceuticals, and soap, benzaldehyde is "generally regarded as safe" (GRAS) by the US FDA[21] and FEMA. As for the appearance, this organic is a clear colorless liquid with an almond-like smell. Reaction of benzaldehyde with anhydrous sodium acetate and acetic anhydride yields cinnamic acid, while alcoholic potassium cyanide can be used to catalyze the condensation of benzaldehyde to benzoin. [9], As of 1999, 7000 tonnes of synthetic and 100 tonnes of natural benzaldehyde were produced annually. Kara, The notation 1.04 g/ml which is read 1.04 grams per millilitre means that every millilitre weighs 1.04 grams. The natural status of benzaldehyde obtained in this way is controversial. The parent of the class of benzoins. Benzaldehyde is commonly employed to confer almond flavor to foods and scented products. He extracted the substance from bitter almonds. "Site-specific nuclear magnetic resonance spectroscopy", which evaluates 1H/2H isotope ratios, has been used to differentiate between naturally occurring and synthetic benzaldehyde. The aniline dye malachite green is prepared from benzaldehyde and dimethylaniline. [10] Liquid phase chlorination and oxidation of toluene are the main routes. Numerous other methods have been developed, such as the partial oxidation of benzyl alcohol, alkali hydrolysis of benzal chloride, and the carbonylation of benzene.[11]. It is the simplest aromatic aldehyde and one of the most industrially useful. This reaction also yields acetaldehyde. Additionally, benzaldehyde is also used as a flavour chemical in JUUL e-cigarette pods, particularly the "Cool Mint", "Cool Cucumber", and "Fruit Medley" varieties.

The primary component of bitter almond oil, benzaldehyde can be extracted from a number of other natural sources. Benzaldehyde contributes to the scent of oyster mushrooms (Pleurotus ostreatus).[15]. 12 grams/mole, Dibenzalacetone: molar mass = 234.29 grams/mole . [17], For a 70 kg human, the lethal dose is estimated at 50 mL. Benzoin is a ketone that consists of acetophenone bearing hydroxy and phenyl substituents at the alpha-position. [14] It is accepted in the European Union as a flavoring agent. [5] Synthetic benzaldehyde is the flavoring agent in imitation almond extract, which is used to flavor cakes and other baked goods.

Later, in 1830s, a German chemist Justus von Liebig and his colleague Friedrich Wöhler investigated the compound in study that in its turn laid the basis for the organic chemistry structural theory. 2005-03-26. Most of the benzaldehyde that people eat is from natural plant foods, such as almonds.[14]. The concentration is relatively low, at ~1 μg/mL. [19] The beekeeper can then remove the honey frames from the bee hive with less risk to both bees and beekeeper. Predicted Melting Point: 55-58 °C J&K Scientific 144999: [11] An acceptable daily intake of 15 mg/day has been identified for benzaldehyde by the United States Environmental Protection Agency.
