0.9152 g/cm 3: Boiling point: 54–57 °C (129–135 °F; 327–330 K) ... Its acetal can be prepared from acrolein. [2] Occurrence in interstellar medium
The toxicity LD 50 of propionitrile is listed as 39 mg/kg [8] and as 230 my (both rats, oral). [7] In 1979, the Kalama (Vega) plant in Beaufort, South Carolina experienced an explosion during the production of propionitrile by nickel-catalyzed hydrogenation of acrylonitrile. [9] This site is now one of the two Superfund cleanup sites in South ...
1,1-Diethoxyethane (acetaldehyde diethyl acetal) is a major flavoring component of distilled beverages, especially malt whisky [3] and sherry. [4] Although it is just one of many compounds containing an acetal functional group, this specific chemical is sometimes called simply acetal .
The reflux condenser contains water heated at 60 °C, which condenses unreacted propanol, but allows propionaldehyde to pass. The propionaldehyde vapor is immediately condensed into a suitable receiver. In this arrangement, any propionaldehyde formed is immediately removed from the reactor, thus it does not get over-oxidized to propionic acid. [3]
The product, CH 3 CH(OCH 2 CH 3) 2, is formally named 1,1-diethoxyethane but is commonly referred to as "acetal". [39] This can cause confusion as "acetal" is more commonly used to describe compounds with the functional groups RCH(OR') 2 or RR'C(OR'') 2 rather than referring to this specific compound — in fact, 1,1-diethoxyethane is also ...
In organic chemistry, cyanopolyynes are a family of organic compounds with the chemical formula HC n N (n = 3,5,7,…) and the structural formula H−[C≡C−] n C≡N (n = 1,2,3,…). Structurally, they are polyynes with a cyano group ( −C≡N ) covalently bonded to one of the terminal acetylene units ( H−C≡C ).
2,2-Dimethoxypropane (DMP) is an organic compound with the formula (CH 3) 2 C(OCH 3) 2. A colorless liquid, it is the product of the condensation of acetone and methanol. DMP is used as a water scavenger in water-sensitive reactions. Upon acid-catalyzed reaction, DMP reacts quantitatively with water to form acetone and methanol. [2]
Acrolein (systematic name: propenal) is the simplest unsaturated aldehyde.It is a colorless liquid with a foul and acrid aroma. The smell of burnt fat (as when cooking oil is heated to its smoke point) is caused by glycerol in the burning fat breaking down into acrolein.
