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]
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.
Examples of aldol reactions in biochemistry include the splitting of fructose-1,6-bisphosphate into dihydroxyacetone and glyceraldehyde-3-phosphate in the fourth stage of glycolysis, which is an example of a reverse ("retro") aldol reaction catalyzed by the enzyme aldolase A (also known as fructose-1,6-bisphosphate aldolase).
Under the usual laboratory conditions, it is unstable, tending instead to undergo self-condensation. [1] Aminoacetaldehyde diethylacetal is a stable surrogate. [2] In nature, aminoacetaldehyde is produced by oxygenation of taurine catalyzed by taurine dioxygenase, which produces the sulfite H 2 NCH 2 CH(OH)SO 3 −.
C 6 H 6 + C 2 H 4 → C 6 H 5 C 2 H 5. The diethylbenzene is an inadvertent side product. C 6 H 5 C 2 H 5 + C 2 H 4 → C 6 H 4 (C 2 H 5) 2. Using shape-selective zeolite catalysts, the para isomer can be produced in high selectivity. Much diethylbenzene is recycled by transalkylation to give ethylbenzene: [1] C 6 H 4 (C 2 H 5) 2 + C 6 H 6 → ...
This reaction produced the 1,6-addition product 2 in 0% yield, the 1,6-addition product 3 in approximately 99% yield, and the 1,4-addition product 4 in less than 2% yield. This particular catalyst and set of reaction conditions led to the mostly regioselective and enantioselective 1,6-Michael addition of ethyl sorbate 1 to product 3 .
