Infobox references. In organic chemistry, methenium (also called methylium, carbenium, [2] methyl cation, or protonated methylene) is a cation with the formula CH+. 3. It can be viewed as a methylene radical (:CH. 2) with an added proton (H+. ), or as a methyl radical (• CH. 3) with one electron removed. It is a carbocation and an enium ion ...
In chemistry, methanium is a complex positive ion with formula [C H 5]+ (metastable transitional form, a carbon atom covalently bonded to five hydrogen atoms) or [CH3(H2)]+ (fluxional form, namely a molecule with one carbon atom covalently bonded to three hydrogen atoms and one dihydrogen molecule), bearing a +1 electric charge.
In September 2018, Channel 3 (owned jointly by BEC and MCOT) was the last broadcaster to broadcast analog television services in Thailand. The network made the move to digital television in late 2019 on VHF while analogue television ceased transmission on 26 March 2020 at 00:00 am (UTC+7), exactly 50 years after the channel's launch.

Trimethylamine (TMA) is an organic compound with the formula N(CH 3) 3.It is a trimethylated derivative of ammonia.TMA is widely used in industry. [5] [6] At higher concentrations it has an ammonia-like odor, and can cause necrosis of mucous membranes on contact. [7]
Acetaldehyde (IUPAC systematic name ethanal) is an organic chemical compound with the formula CH 3 CHO, sometimes abbreviated as Me CHO. It is a colorless liquid or gas, boiling near room temperature. It is one of the most important aldehydes, occurring widely in nature and being produced on a large scale in industry.
Ethylamine, also known as ethanamine, is an organic compound with the formula CH 3 CH 2 NH 2. This colourless gas has a strong ammonia -like odor. It condenses just below room temperature to a liquid miscible with virtually all solvents. It is a nucleophilic base, as is typical for amines.
Methyl acetate is produced industrially via the carbonylation of methanol as a byproduct of the production of acetic acid. [6] Methyl acetate also arises by esterification of acetic acid with methanol in the presence of strong acids such as sulfuric acid; this production process is famous [according to whom?] because of Eastman Kodak's intensified process using a reactive distillation.
