OK; No; HCOOCH3+NaOH===HCoOH+CH3OH+H2O condition is heating.
Isn't that the complete hydrolysis of esters in an alkaline solution?
You're a senior in high school, and you still have time to ask this kind of question, so it's better to ask the teacher if you don't know what.
-
Yes, the equation is ch3....ch2...coor+ naoh= ch3...
ch2...Coona + RoH, Na can react with NaOH in solution, but I don't know if it can react with NaOH solids, you didn't clear it, so it's not good, and it's not divided, so it's the only way.
-
Yes, does Na react with NaOH solution I know.
Na does not react with NaOH but with water in solution: 2Na + 2H20 = = 2NaOH + H2
-
Esters can react with sodium hydroxide, which is a property of esters in high and high stages. Na does not react with sodium hydroxide unless sodium hydroxide is a solution.
-
Esters can be combined with Naoh and sodium carboxylate.
Na can react with water in NaOH solution, NaOH solid does not reflect the original hydroxy--
Whether it is an alcohol hydroxyl group or a phenolic hydroxyl group, it should be reflected with NA.

Reaction chemical formula: CH3COOC2H5+NaOH CH3COONA+CH3CH2OH. Sodium hydroxide, also known as caustic soda.
Caustic soda, solid soda, caustic soda.
Caustic soda. Sodium hydroxide has strong alkaline and strong corrosiveness, and can be used as acid neutralizer, masking agent, precipitant, precipitation masking agent, chromogenic agent, saponifying agent, peeling agent, detergent, etc., and has a wide range of uses.
Ester refers to the product formed by the esterification reaction of alcohols and carboxylic acids or inorganic oxygenated acids in organic chemistry. It is widely found in the Ziqiao Qingran realm, for example, ethyl acetate is found in wine, vinegar and some fruits; Isoamyl acetate is found in fruits such as bananas and pears; Methyl benzoate is present in clove oil; Methyl salicylate is found in wintergreen oil. Glycerides of higher and intermediate fatty acids are the main components of animal and vegetable oils and fats, and esters formed by higher fatty acids and higher alcohols are the main components of waxes.

The chemical equation for the reaction of ester group and sodium hydroxide: C7H6O6S+3NaOH==C7H3O6Na3+3H2O.
The process of ester hydrolysis of sodium hydroxide does not participate in the reaction, and one mole of alcohol ester bond hydrolysis produces one mole of alcohol and one mole of carboxylic acid, but the alcohol does not react with sodium hydroxide, and carboxylic acid consumes one mole of sodium hydroxide.
One mole of phenol ester bonds is hydrolyzed to form one mole of phenol and one mole of carboxylic acid, and phenol and carboxylic acid each consume one mole of sodium hydroxide, a total of two moles. It is also possible to judge how many moles are consumed according to this principle.
The ester group is first hydrolyzed into acid and alcohol, and one mole of ester group should be able to hydrolyze one molar acid and one molar alcohol, and one mole of acid reacts with one molar of pure sodium hydroxide.
Sometimes, after the hydrolysis of one mole of ester group, the result is molar acid and one mole of phenol, in addition to the reaction of one mole of acid and one mole of sodium hydroxide, one mole of phenol can also react with one mole of sodium hydroxide.
Alkaline hydrolysis occurs in an aqueous solution of sodium hydroxide, which is reduced to the previous acids and alcohols. Benoesters and sodium hydroxide undergo a hydrolysis reaction. In the process of reaction between ester group and sodium hydroxide, ester can be regarded as the formation of alcohol and acid, and after a small amount of hydrolysis of the ester group, because the alkali neutralizes the carboxylic acid in the product.
The equilibrium in this process, the forward movement is not a real reaction, but the hydrolysis rate of the ester group is faster, that is to say, sodium hydroxide plays a promoting role in the process of ester hydrolysis.
-
Good evening, esters are available in sodium hydroxide.
Alkaline hydrolysis occurs in aqueous solutions that are reduced to previous acids and alcohols, such as ethyl acetate.
It can be hydrolyzed to regenerate acetic acid and ethanol.
Higher fatty acid esters can be saponified with sodium hydroxide to produce some anionic surfactants.
-
It is the hydrolysis of esters, i.e., the saponification reaction is carried out in an alkaline solution. Whether it is complete or not depends on the impetus of the reaction, and whether the reaction can be carried out in a positive direction.
For simple esters, under alkaline conditions, such as methyl esters, hydrolysis into carboxylic acids and methanol, and carboxylic acid withering can further undergo acid-base reactions to form carboxylates, thus promoting the positive progress of equilibrium. Another example is the production of soap, which produces sodium of the higher fatty acids, which precipitates and causes the reaction to move forward.
However, for large tert-butyl esters, due to steric hindrance, the base is not easy to attack the ester group, so the reaction is usually slow and difficult to hydrolyze completely. However, under the condition of acid feasting skin cavity, protonation is easier than alkali attack, and the generated tert-butanol will be further eliminated into butylene, so that the equilibrium is shifted positively and the hydrolysis reaction is complete.
In general, for simple esters, which are common methyl esters, ethyl esters, etc., alkaline hydrolysis is usually used.
For sterically hindered esters, such as tert-butyl esters, acid hydrolysis is often used.
-
Because the ester group is formed into carboxylic acid and alcohol, and then the carboxylic acid and NaOH react to form the sodium salt of the acid, and NaOH plays a role in promoting the hydrolysis of esters, so it is called hydrolysis reaction.
The compound is decomposed into two parts, H+ in water is added to one part, and hydroxyl group (-OH) is added to the other part, so that the reaction process of two or more new compounds is obtained; The concept of inorganic chemistry is the reaction of weak acids or weak base ions with water to form weak acids and hydroxide ions (OH-) (or weak bases and hydrogen ions (H+)).
Organic hydrolysis reaction.
The molecules of organic matter are generally relatively large, and hydrolysis requires acids or bases as catalysts, and sometimes bioactive enzymes as catalysts.
In acidic aqueous solutions, fats are hydrolyzed into glycerol and fatty acids; Starch will be hydrolyzed into maltose, glucose, etc.; Proteins are hydrolyzed into substances with relatively small molecular weights, such as amino acids.
In an alkaline aqueous solution, fats are broken down into glycerol and solid fatty acid salts, known as soaps, so this hydrolysis is also called saponification.
The most industrially used is the hydrolysis of organic matter, mainly to produce alcohols and phenols. The hydrolysis reaction is the reverse reaction of the neutralization or esterification reaction. The hydrolysis of most organic compounds is difficult to carry out smoothly with water alone.
Depending on the nature of the hydrolysate, the hydrolytic agent can be sodium hydroxide aqueous solution, dilute acid or concentrated acid, and sometimes potassium hydroxide, calcium hydroxide, sodium bisulfite, etc. This is called alkaline hydrolysis and acid hydrolysis.
Hydrolysis can be carried out in batch or continuous mode, with the former usually taking place in a kettle reactor and the latter mostly using a tower reactor.
-
The so-called hydrolysis reaction, in layman's terms, is a reaction with water (don't take this sentence seriously). The reaction between the lipid group and sodium hydroxide is basically that the lipid group reacts with water to form an acid, and then the acid and the base react again. The first step in this is the hydrolysis reaction.
-
Because the ordinary ester group is hydrolyzed to produce alcohol and carboxylic acid, sodium hydroxide only neutralizes with carboxylic acid, so 1mol ester consumes 1mol of sodium hydroxide.
The phenol ester and sodium hydroxide are hydrolyzed to form carboxylic acid and phenol, both of which can react with sodium hydroxide to form sodium phenol and sodium carboxylate, so 1mol of phenol ester can react with 2mol of sodium hydroxide.

The reaction equation between ester and sodium hydroxide is rcooch2r+naoh=rcoona+rch2oh, ester refers to the product of esterification of alcohol and carboxylic acid or inorganic oxygenated acid in organic chemistry, which is widely found in nature, such as ethyl acetate is found in wine, vinegar and some fruits.
Sodium hydroxide, also known as caustic soda, caustic soda, solid soda, caustic soda, caustic soda. Sodium hydroxide is strongly alkaline and corrosive, and can be used as acid neutralizer, masking agent, precipitant and precipitation masking agent. Brother Filial Piety.
