Phenylacetaldehyde is an aldehyde that consists of acetaldehyde bearing a phenyl substituent; the parent member of the phenylacetaldehyde class of compounds. It has a role as a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is an alpha-CH2-containing aldehyde and a member of ...
The German chemist Valentin Hermann Weidenbusch (1821–1893) synthesized paraldehyde in 1848 by treating acetaldehyde with acid (either sulfuric or nitric acid) and cooling to 0 °C (32 °F). He found it quite remarkable that when paraldehyde was heated with a trace of the same acid, the reaction went the other way, recreating acetaldehyde. [38]
Phenylacetic acid (conjugate base phenylacetate), also known by various synonyms, is an organic compound containing a phenyl functional group and a carboxylic acid functional group. It is a white solid with a strong honey-like odor. Endogenously, it is a catabolite of phenylalanine.
DMA is prepared commercially by the reaction of dimethylamine with acetic anhydride or acetic acid. Dehydration of the salt of dimethylamine and acetic acid also furnishes this compound: [5] CH 3 CO 2 H·HN(CH 3) 2 → H 2 O + CH 3 CON(CH 3) 2. Dimethylacetamide can also be produced by the reaction of dimethylamine with methyl acetate. [6]
Phenyl acetate is the ester of phenol and acetic acid.It can be produced by reacting phenol with acetic anhydride or acetyl chloride.. Phenyl acetate can be separated into phenol and an acetate salt, via saponification: heating the phenyl acetate with a strong base, such as sodium hydroxide, will produce phenol and an acetate salt (sodium acetate, if sodium hydroxide were used).
Dioxolane is a heterocyclic acetal with the chemical formula (CH 2) 2 O 2 CH 2.It is related to tetrahydrofuran (THF) by replacement of the methylene group (CH 2) at the 2-position with an oxygen atom.

With water and a protic acid such as sulfuric acid as the reaction medium and formaldehyde the reaction product is a 1,3-diol (3). When water is absent, the cationic intermediate loses a proton to give an allylic alcohol (4). With an excess of formaldehyde and a low reaction temperature the reaction product is a dioxane (5).
