What is the chemical structure of 1R- (-) -camphor-10-sulfonic acid?
1R -( - ) - chemical-10-acid chemistry is the key to exploring the chemical domain. Its analysis depends on the analytical method of the chemical principle.
1R -( - ) - chemical-10-acid, containing a specific atom to form a hollow arrangement. Its molecules may have a specific functional group, and its chemical properties are very important.
As far as chemical chemistry is concerned, it may be formed by atoms such as carbon, oxygen, etc. in a specific way. The carbon frame is its basic skeleton, and the atoms are formed in a common phase. The position of the functional group determines its characteristics. Functional groups such as alkyl groups and carboxylic groups make molecules have water-based or acidic properties.
Or there are vertical radicals, 1R -( - ) a specific phenotype. This phenotype has a deep impact on molecular activity and interactions with other molecules. A specific phenotype enables molecules to be bound or reacted to in a specific way, and the rate of reflection can be determined.
To clarify its transformation, multiple analytical techniques can be used. Such as nuclear magnetic resonance spectroscopy, it can provide information on the location, mesh and phase of atoms in molecules; external light can be used to determine functional groups; and molecular weight can be determined. Molecular fragments can be used to help improve the evaluation.
For example, 1R -( - ) - -10-acid chemistry is composed of elements such as atomic formation, functional groups, and functional groups. Multi-analytical techniques can help to understand this and refine it.
1R- (-) -camphor-10-sulfonic acid is commonly used in which chemical reactions
1R -( - )- mechanical-10-carboxylic acid is often used in esterification reaction, acylation reaction, carboxylic reaction, etc.
Esterification reaction, carboxylic acid alcohol under the action of acid catalysis, co-generation of ester water. For example, acetic acid and ethanol reaction, catalyzed by sulfuric acid, plus, to form ethyl acetate water. The equation is:\ (CH_ {3} COOH + C_ {2} H_ {5} OH\ underset {\ triangle} {\ overset {H_ {2} SO_ {4}}} {\ rightleftharpoons}} CH_ {3} COOC_ {2} H_ {5} + H_ {2} O\). In this reaction, the hydration of the carboxyl group of the carboxylic acid is an important way for ester compounds.
Acylation reaction, carboxylic acid can be acylated such as acyl, acid anhydride, etc., to form acyl derivatives. For example, acetic acid and acetic anhydride can be used to obtain acetyl acetic acid. This reaction is often used in the synthesis of carboxylic acids to introduce acyl functional groups to improve the properties of compounds.
Carboxylic reaction is the reaction of carboxylic acids losing their carboxyl groups and releasing carbon dioxide. Some specific carboxylic acids, when added or in the presence of catalysts, are easy to generate carboxylic acids. For example, pyruvate can be carboxylated to form acetaldehyde and carbon dioxide under the action of carboxylase. This reaction also plays an important role in the new generation of biological processes.
Therefore, 1R -( - )- mechanical-10-carboxylic acids play an important role in polymorphism, and can be derived from polymorphism compounds through different polymorphisms.
What are the physical properties of 1R- (-) -camphor-10-sulfonic acid
1R -( - )--10-lactic acid is a chemical compound, which has a general physical property.
Lactic acid is a liquid-colored to light-colored liquid, and it is often determined under normal conditions. Its melting temperature is 16.8 ° C, which means that the degree is lower than this value. Lactic acid is solidified by a liquid, just like water when it is cold and ice, but its melting phase is slightly higher than 0 ° C.
In terms of boiling temperature, lactic acid boils at 122 ° C (2 kPa), indicating that under a specific environment, it needs to be added to this degree before lactic acid can boil, and it can be boiled by a liquid, just as the daily water is boiled at 100 ° C (1 large).
The density of lactic acid is 1.209g/cm ³, and the density of water is slightly larger than 1g/cm ³. Therefore, if lactic acid is mixed with water, the lactic acid will sink to the bottom of the water at the initial stage when it is fully mixed and the two are immiscible.
In terms of solubility, lactic acid is easily soluble in water, ethanol, ether, etc. This property is due to the fact that the molecule contains a carboxyl group (-OH) and a carboxyl group (-COOH), both of which are water-based, so that it can form water molecules. It is similar to the fact that there are many tiny "seeds" of lactic acid molecules in water molecules, so it can be miscible in water in any ratio, and can also be well dissolved in ethanol, ether, etc.
In addition, lactic acid is optically active because of the presence of chiral centers in its molecules, which is of the 1R- (-) type, which allows it to spin polarized light and has its special significance in the optical field.
How to detect the purity of 1R- (-) -camphor-10-sulfonic acid
To check the degree of acid in the 1R -( - ) - machine 10, the following method can be used.
First, the required equipment, such as a fine gauge, should be used. Take a certain amount of the 1R -( - ) - machine 10-acid product and use the method of titration. It is appropriate to indicate that the liquid of known degree should be dripped slowly. The color of the solution should be checked. To be titrated, the amount of liquid consumed should be determined. According to the amount of the reaction, the acid content in the product can be calculated, and the degree of acid can be inferred.
Or by means of chromatograph, liquid chromatograph, etc. The product is processed and injected into the color. Depending on the surface or height of the color peak, the ratio of the components in the product can be refined to obtain 1R -( - ) - 10-acid degree.
Or by melting method. The material does not have a fixed melting rate. If the 1R -( - ) - machine 10-shows that the acid contains water, the melting rate must be reduced and the melting range will also increase. Based on the melting time of the refined product, the melting time and melting process of the refined product can be roughly judged by comparing the cultural value of the refined product.
What is the market price of 1R- (-) -camphor-10-sulfonic acid?
I want to know what the market price of 1R -( - )- machinery-10-lactic acid is. This test is for you.
1R -( - )- machinery-10-lactic acid, the price in the market often varies depending on the quality, purity, and supply and demand. If its purity is quite good and it is needed in the market, the price may be high.
In today's city, generally speaking, the price per kilogram is between hundreds and thousands of yuan. If the purity is extremely high and the experimental grade is reached, the price is even higher, or thousands of yuan per kilogram or even higher. However, if it is a general industrial user, due to the large demand and abundant output, the price may be slightly lower, or hundreds of yuan per kilogram.
Furthermore, changes in market supply and demand also affect its price. If there are many people who want it, but there are few suppliers, the price will rise; conversely, if the supply exceeds the demand, the price will go down. To know the exact price, when you carefully observe the market situation and consult the supplier, you can get a more accurate value.
