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
46 to 50 °C (115 to 122 °F; 319 to 323 K) Solubility in water. 20 g/100 mL ... Propionaldehyde or propanal is the organic compound with the formula CH 3 CH 2 CHO.
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 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 ...
ch 3 ch 2 ch 2 oh + o 2 + nh 3 → ch 3 ch 2 c≡n + 3 h 2 o Propionitrile is a byproduct of the electrodimerisation of acrylonitrile to adiponitrile . In the laboratory propanenitrile can also be produced by the dehydration of propionamide , by catalytic reduction of acrylonitrile , or by distilling ethyl sulfate and potassium cyanide .
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]
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 ).
At room temperature, acetaldehyde (H 3 CC(O)H) is more stable than vinyl alcohol (H 2 C=CHOH) by 42.7 kJ/mol. [3] Vinyl alcohol gas isomerizes to the aldehyde with a half-life of 30 min at room temperature. [1] H 2 C=CHOH → H 3 CC(O)H The industrial synthesis of acetaldehyde (Wacker process) proceeds via the intermediacy of a vinyl alcohol ...
