Diacetyl (/ d aɪ j ə ˈ s iː t ə l / dy-yuh-SEE-tuhl; IUPAC systematic name: butanedione or butane-2,3-dione) is an organic compound with the chemical formula (CH 3 CO) 2. It is a yellow liquid with an intensely buttery flavor. It is a vicinal diketone (two C=O groups, side-by-side).
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. It is miscible with most organic solvents.
It is a precursor to many fine chemicals. A prominent industrial example is the crossed aldol condensation with diethyl ketone to give trimethylcyclohexenone, this can be easily converted to trimethylhydroquinone, which is a precursor to the vitamin E. [8] Other derivatives include crotonic acid, 3-methoxybutanol and the food preservative ...
Dali opened its first store in February 2020 in Santa Rosa, Laguna, and by the end of 2022, it had at least 250 stores in the Philippines. [2] In March 2023, the Asian Development Bank (ADB) invested US$15 million to support the retail chain's expansion. [4]
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 .
CH 3 CH=CH 2 + H 2 O + 2 CO → CH 3 CH 2 CH 2 CH 2 OH + CO 2. In former times, butanol was prepared from crotonaldehyde, which can be obtained from acetaldehyde. Butanol can also be produced by fermentation of biomass by bacteria. Prior to the 1950s, Clostridium acetobutylicum was used in industrial fermentation to produce butanol. Research in ...

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 ...
