3-Nitrobenzaldehyde is an organic compound with the formula O 2 NC 6 H 4 CHO. It is one of three isomers of nitrobenzaldehyde. It contains a nitro group meta-substituted to the aldehyde. 3-Nitrobenzaldehyde is the primary product obtained via the mono-nitration of benzaldehyde with nitric acid. [3] C 6 H 5 CHO + HNO 3 → O 2 NC 6 H 4 CHO + H 2 O
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.

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 ...
(However, PE only dissolves at temperatures well above 100 °C.) Poly(styrene) has a solubility parameter of 9.1 cal 1/2 cm −3/2, and thus ethyl acetate is likely to be a good solvent. Nylon 6,6 has a solubility parameter of 13.7 cal 1/2 cm −3/2, and ethanol is likely to be the best solvent of those tabulated. However, the latter is polar ...
4-Nitrobenzaldehyde is an organic compound with the formula O 2 NC 6 H 4 CHO. It is one of three isomers of nitrobenzaldehyde. It contains a nitro group para-substituted to an aldehyde. 4-Nitrobenzaldehyde is obtained by oxidation of 4-nitrotoluene or hydrolysis of 4-nitrobenzalbromide: [3] O 2 NC 6 H 4 CHBr 2 + H 2 O → O 2 NC 6 H 4 CHO + 2 HBr
