Anonymous users2024-02-09The four common substitution reactions of ethanol include catalyzed alcohol esterification, haloalkylation, electrophilic substitution, and etherification. Their equations are as follows:
1.Alcohol esterification reaction:
c2h5oh + ch3cooh ch3cooc2h5 + h2o2.Alkylation of halogenation:
c2h5oh + hcl c2h5cl + h2o3.Electrophilic substitution reaction:
c2h5oh + hbr c2h5br + h2o4.Etherification reaction:
2c2h5oh c2h5oc2h5 + h2o It is worth noting that these equations only simplify the reaction process, and a catalyst or specific conditions may be required to facilitate the reaction. In addition, the by-products and yield of the reaction may vary depending on the experimental conditions.

Substitution of alkyl groups: Ethanol reacts with alkyl halides to form ether compounds.
Acid-catalyzed dehydration: Ethanol reacts with acid catalysts such as concentrated sulfuric acid to form ethylene.
Oxidation: Ethanol reacts with oxygen or oxidants to form acetaldehyde or acetic acid.
Hydrogenation: Ethanol reacts with a catalyst such as platinum or nickel to produce ethane.

Anonymous users2024-02-05Ethanol distillation is a chemical process in which an aqueous ethanol solution is separated from the pure ethanol product through distillation technology. This process is based on the difference in the boiling points of ethanol and water, by heating the mixture at a certain temperature so that the ethanol evaporates first, and then condenses and collects the pure ethanol spike. This process uses the phase transformation characteristics of substances at different temperatures to achieve the separation of different components.
The equation for the chemical model of the ethanol distillation reaction is as follows:
ch3ch2oh + heat ch3ch2oh vaporch3ch2oh vapor ch3ch2oh liquid where ch3ch2oh represents the ethanol molecule, the arrow indicates the direction of the chemical reaction, and heat represents the energy source that provides heat.

1. Beijing (Beijing).
The first well-documented name in Beijing was "Ji", which was the capital of the Yan Kingdom during the Spring and Autumn Period and the Warring States Period. Liaojin used Beijing as the accompanying capital and called it Yanjing. After Jin destroyed Liao, the capital was moved here, called the central capital. >>>More
