From the simple and crude at the beginning to the fine and complete today, every step has condensed the wisdom of the predecessors. Therefore, citric acid anhydrous substances play an important role in various industries, and its development process has witnessed the prosperity of chemical technology.
Product Overview
"On Anhydrous Citric Acid"
Now there is a thing called anhydrous citric acid, which is a delicate product of chemistry. It is a colorless translucent crystal or white particle, or a white crystalline powder, odorless and extremely acidic.
Looking at its properties, it is slightly weathered in dry air and deliquescent in humid air. It is easily soluble in water, easily soluble in ethanol, and slightly soluble in ether.
It has a wide range of uses. In the food industry, it is often used as an acidic agent, solubilizer, buffer, antioxidant, etc., to give food its unique flavor and prolong shelf life. In the field of medicine, it can be used as a pharmaceutical coolant, flavoring agent, etc., to help the efficacy of drugs. In industry, it is also indispensable in the manufacture of detergents, cosmetics and other products to improve product performance.
This anhydrous citric acid, with its unique properties, is used in all fields, and it is actually a good product in the chemical industry.
Physical & Chemical Properties
"On the Physical Properties and Chemical Properties of Anhydrous Citric Acid"
Anhydrous citric acid is a commonly used product in the chemical industry. Its physical properties are white and crystalline in color, like fine sand, pure and clean. Under normal temperature, it is stable and safe, but when exposed to high temperature, it gradually melts into a liquid, which is a physical change.
In terms of chemical properties, it has the general properties of acids and can combine with bases to produce corresponding salts. In the field of organic synthesis, it is often a catalyst, which promotes the speed of reaction and increases the rate of production. It also reacts with metals and can dissolve some metals to form metal salts. This is the materialization of anhydrous citric acid, which is of great use in chemical, food and other industries. It is related to people's livelihood and cannot be underestimated.
Technical Specifications & Labeling
"Technical Specification and Identification of Citric Acid Anhydrous Substances (Product Parameters) "
Citric acid anhydrous substances are commonly used in chemical industry. Its technical specifications are related to the quality. As far as its physical properties are concerned, it should be white and powder or crystalline, with no impurities visible to the naked eye.
In terms of chemical properties, the purity must reach a very high standard, and the impurities contained should be minimal. Its identification (product parameters) is also very critical. If the content is one item, it needs to be accurately marked, and there must be no difference in the slightest pool. This is the essence of the technical specification and identification (product parameters) of citric acid anhydrous substances, which is related to production and application, and cannot be ignored.
Preparation Method
"On the Preparation of Anhydrous Citric Acid"
If you want to make anhydrous citric acid, the first raw material. When taking high-quality fresh lemon fruit, or carefully selected from natural fermentation products. The preparation process is based on fermentation method.
When fermenting, select suitable strains, such as Aspergillus niger, in a medium rich in sugar and nutrients, control temperature and humidity, so that it can be fully metabolized to produce citric acid. After fermentation, separate. Ion exchange, extraction and other methods are used to remove impurities to obtain crude citric acid.
Then purified, the crude product is crystallized and recrystallized many times to remove residual impurities and improve purity. In this process, precise temperature control and rate make the crystallization perfect. The final product is high-purity anhydrous citric acid. The whole preparation, the raw materials are carefully selected and the process is rigorous to obtain high-quality products.
Chemical Reactions & Modifications
Citric Acid Anhydrous, in the field of chemistry, its reaction and modification are worth exploring. Its dry and pure, in all kinds of reactions, every key use. In case of alkali, it will be combined and synthesized into salt, which is a common acid-base reaction. And in the way of catalysis, it can also develop its effect, promote the speed of the reaction, and change the quality of the product.
As for the way of modification, or add other agents to adjust its properties, or change the temperature and pressure to change its structure. Through this act, it can be used to expand its use and expand its path. In the food industry, when it can adjust the flavor and increase the quality; in the world of medicine, it can help the preparation and improve the stability of the drug effect. Therefore, the study of its chemical reaction and modification is essential to explore its new application.
Synonyms & Product Names
Citric acid anhydrous substance, its synonym and trade name, is also a matter of our investigation. Citric acid anhydrous substance, also known as anhydrous citric acid. The two refer to the same thing. In inter-city trade, both are common names. The name of anhydrous citric acid is concise and clear, directly referring to its anhydrous nature; and the name of anhydrous citric acid also follows its quality and means accurately. Merchants use both names, either because of habit or for marketing convenience. However, the root of it refers to the removal of citric acid from crystalline water. Both are widely used in chemical, food and other fields, and their effects are the same. Although the names are different, the quality is the same.
Safety & Operational Standards
Specifications for the Safety and Operation of Anhydrous Citric Acid
Anhydrous citric acid is widely used in various fields of chemical industry. However, if you want to ensure that everything goes smoothly, it is safe and secure. The operation is in accordance with regulations, and the specifications must be clear.
Safety first. Although this agent is not a highly toxic product, it should not be ignored. If it touches the skin, rinse quickly with water, and it may cause discomfort for a long time. If it enters the eyes, it is even more urgent to rinse it with a large amount of water, and seek medical treatment to avoid damage to the eyes. If you inhale it accidentally, leave it quickly and go to a well-ventilated place. If swallowed, do not induce vomiting, and seek medical attention immediately. When stored, it should be placed in a cool and dry place, away from fire and heat sources, and separated from oxidants and alkalis to prevent their reaction from causing danger.
As for the operating specifications. Where this agent is involved, it is necessary to adapt protective equipment, such as gloves, goggles, etc. When weighing, measure accurately and follow the instructions. When dissolving, pour it slowly into the water, not the other way around, to prevent splashing. Stir slowly to make it evenly soluble. After use, properly clean up the utensils, and dispose of the residual agent according to regulations. Do not discard it at will.
In short, the use of anhydrous citric acid is safe and follows the rules of operation. In this way, everything goes smoothly, and it can be used to the best of its ability.
