Methanol (also called methyl alcohol and wood spirit, amongst other names) is an organic chemical compound and the simplest aliphatic alcohol, with the chemical formula C H 3 OH (a methyl group linked to a hydroxyl group, often abbreviated as MeOH).
Aspartame is an artificial non-saccharide sweetener 200 times sweeter than sucrose and is commonly used as a sugar substitute in foods and beverages. [4] It is a methyl ester of the aspartic acid/phenylalanine dipeptide with brand names NutraSweet, Equal, and Canderel. [4]

These alembics often featured a cooling system around the beak, using cold water, for instance, which made the condensation of alcohol more efficient. These were called pot stills . Today, the retorts and pot stills have been largely supplanted by more efficient distillation methods in most industrial processes.
Later the meaning of alcohol was extended to distilled substances in general, and then narrowed again to ethanol, when "spirits" was a synonym for hard liquor. [14] Paracelsus and Libavius both used the term alcohol to denote a fine powder, the latter speaking of an alcohol derived from antimony.
The origin of this word cannot be conclusively attributed to Malayalam or Tamil. Congee, porridge, water with rice; uncertain origin, possibly from Tamil kanji (கஞ்சி), [7] Telugu or Kannada gañji, or Malayalam kaññi (കഞ്ഞി). [citation needed] Alternatively, possibly from Gujarati, [8] which is not a Dravidian language.
When free hydroxyl groups are transformed to acetoxy groups, the ability of the wood to absorb water is greatly reduced, rendering the wood more dimensionally stable and, because it is no longer digestible, extremely durable. In general, softwoods naturally have an acetyl content from 0.5 to 1.5% and more durable hardwoods from 2 to 4.5%.
Wood science [1] is the scientific field which predominantly studies and investigates elements associated with the formation, the physical and chemical composition, and the macro- and microstructure of wood as a bio-based and lignocellulosic material.
