4-tert-Butylbenzaldehyde is notable as a rare example of industrial-scale electrochemistry. It is produced by BASF and Givaudan (typically as its methanol acetal) through a double anodic oxidation of 4-tert-butyltoluene on greater than 10,000 ton per year scale. [2] [3]
Substrates are broadly limited to methyl ketones and secondary alcohols oxidizable to methyl ketones, such as isopropanol.The only primary alcohol and aldehyde to undergo this reaction are ethanol and acetaldehyde, respectively. 1,3-Diketones such as acetylacetone also undergo this reaction. β-ketoacids such as acetoacetic acid will also give the test upon heating.
Amygdalin 2 H 2 O HCN benzaldehyde 2 × glucose 2 × Benzaldehyde contributes to the scent of oyster mushrooms (Pleurotus ostreatus). Reactions Benzaldehyde is easily oxidized to benzoic acid in air at room temperature, causing a common impurity in laboratory samples. Since the boiling point of benzoic acid is much higher than that of benzaldehyde, it may be purified by distillation. Benzyl ...
Diacetylene (also known as butadiyne) is the organic compound with the formula C 4 H 2. It is the simplest compound containing two triple bonds . It is first in the series of polyynes , which are of theoretical but not of practical interest.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
C 9 H 10 O: Molar mass: 134.178 g·mol −1 Appearance clear colourless to slightly yellow liquid Density: 1.001 g/mL Boiling point: 221.7 °C (431.1 °F; 494.8 K)
Aminoacetaldehyde is the organic compound with the formula OHCCH 2 NH 2.Under the usual laboratory conditions, it is unstable, tending instead to undergo self-condensation. [1]
Aldol structural units are found in many important molecules, whether naturally occurring or synthetic. [8] [9] The reaction is well used on an industrial scale, notably of pentaerythritol, [10] trimethylolpropane, the plasticizer precursor 2-ethylhexanol, and the drug Lipitor (atorvastatin, calcium salt).
