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]
Butyraldehyde, also known as butanal, is an organic compound with the formula CH 3 (CH 2) 2 CHO. This compound is the aldehyde derivative of butane . It is a colorless flammable liquid with an unpleasant smell.
In organic chemistry, an acetal is a functional group with the connectivity R 2 C(OR') 2. Here, the R groups can be organic fragments (a carbon atom, with arbitrary other atoms attached to that) or hydrogen , while the R' groups must be organic fragments not hydrogen.
Benzaldehyde (C 6 H 5 CHO) is an organic compound consisting of a benzene ring with a formyl substituent. It is among the simplest aromatic aldehydes and one of the most industrially useful. It is a colorless liquid with a characteristic almond -like odor , and is commonly used in cherry -flavored sodas . [ 5 ]
Levi and Zanetti extended the Knorr synthesis in 1894 to the use of acetylacetone (2,4-pentanedione) in reaction with ethyl 2-oximinoacetoacetate. The result was ethyl 4-acetyl-3,5-dimethylpyrrole-2-carboxylate, where "OEt" = R 1 = R 3 = Me, and R 2 = COOEt. [9] The 4-acetyl group could easily be converted to a 4-ethyl group by Wolff-Kishner ...
In a 2003 study it was found that in vitro, bourgeonal acts as a chemo-attractant for human spermatozoa, activating an olfactory receptor called OR1D2 (formerly called hOR17-4) [2] which opens calcium ion channels in the sperm, leading them to swim twice as fast. [3] Bourgeonal is suspected to be involved in helping sperm locate the ovum.
Dibutoxymethane is an oligoether (more than one -O- grouping) or acetal containing two butyl groups and a methylene grouping. [1] It is used in cosmetics, as a cleansing agent, or solvent. It reduces the formation of soot and nitrogen oxides when added to diesel fuel. [ 2 ]
ClC 6 H 4 NO 2 + 2 NH 3 → H 2 NC 6 H 4 NO 2 + NH 4 Cl H 2 NC 6 H 4 NO 2 + 3 H 2 → H 2 NC 6 H 4 NH 2 + 2 H 2 O. In the laboratory, the reduction of the nitroaniline is effected with zinc powder in ethanol, followed by purification of the diamine as the hydrochloride salt. Darkened impure samples can be purified by treatment of its aqueous ...
