Benzyl alcohol/Density
What is the density of benzyl alcohol in g mL?
1.045 g/mL
1.045 g/mL at 25 °C (lit.)
How do you synthesize benzyl alcohol?
Preparation. Benzyl alcohol is produced industrially from toluene via benzyl chloride, which is hydrolyzed: C6H5CH2Cl + H2O → C6H5CH2OH + HCl. Another route entails hydrogenation of benzaldehyde, a by-product of the oxidation of toluene to benzoic acid.

Which reagent can be used to convert benzyl alcohol to benzaldehyde?
Traditionally, oxidation of benzyl alcohol to benzaldehyde is performed with stoichiometric amounts of chromium (VI) reagents. These oxidants are not only relatively expensive, but also they generate copious amounts of heavy-metal waste.
What is formed in the autoxidation of benzaldehyde?
Benzaldehyde readily undergoes autoxidation to form benzoic acid on exposure to air at room temperature.
How do you synthesize benzaldehyde?
Industrially, benzaldehyde is made by a process in which toluene is treated with chlorine to form benzal chloride, followed by treatment of benzal chloride with water. Benzaldehyde is readily oxidized to benzoic acid and is converted to addition products by hydrocyanic acid or sodium bisulfite.
How do you make benzyl alcohol from benzaldehyde?
Benzyl alcohol is produced industrially from toluene via benzyl chloride, which is hydrolyzed: C 6 H 5 CH 2 Cl + H 2 O → C 6 H 5 CH 2 OH + HCl Another route entails hydrogenation of benzaldehyde, a by-product of the oxidation of toluene to benzoic acid.
What is benzaldehyde dibenzyl acetal (bdba)?
An impurity in benzyl alcohol was identified as benzaldehyde dibenzyl acetal (BDBA). The component BDBA is reversibly formed by the reaction of benzyl alcohol with benzaldehyde, an oxidative degradation product of benzyl alcohol.
How is benzaldehyde synthesized?
In 1832, Friedrich Wöhler and Justus von Liebig first synthesized benzaldehyde. As of 1999, 7000 tonnes of synthetic and 100 tonnes of natural benzaldehyde were produced annually. Liquid phase chlorination and oxidation of toluene are the main routes.
Can benzaldehyde be used as a preservative in injectable formulation?
Some caution is necessary if a high percent of Benzyl alcohol is used as benzaldehyde arises from benzyl alcohol when used as preservative in an injectable formulation solution.
