Introduction of the product
Introduction to the analysis of Citric Acid Mondydrate
Molecular formula: C6H8O7-H2O.
Molecular weight: 210.14.
Properties: density 1.54. melting point 135-152℃. Flash point 173.9℃. Water solubility 1630 g/L (20℃).
It is mainly used in food and beverage industry as acidifier, flavoring agent, preservative and freshness-keeping agent. It is also used as antioxidant, plasticizer and detergent in chemical industry, cosmetic industry and washing industry.
The difference between Citric Acid Mondydrate and Anhydrous Citric Acid is as follows:
1. Different application fields
Citric Acid Mondydrate is mainly used in food and beverage industry as acidulant, flavoring agent and preservative, freshness-keeping agent. It is also used as antioxidant, plasticizer and detergent in chemical industry, cosmetic industry and washing industry.
Anhydrous citric acid is mainly used in food and beverage industry as acidulant, acidity regulator, flavoring agent, preservative and freshness-keeping agent. Anhydrous citric acid is widely used in the national economy, and many industrial sectors need anhydrous citric acid. The sector that uses anhydrous citric acid most is the manufacture of chemicals.
It is followed by paper making, aluminum refining, tungsten refining, rayon, artificial cotton and soap manufacturing. In addition, in the production of dyes, plastics, pharmaceuticals and organic Intermediates, the regeneration of old rubber, the system of sodium metal, water electrolysis and the production of inorganic salts, the production of borax, chromium salts, manganate, phosphate, etc., but also to use a lot of anhydrous citric acid. At the same time, anhydrous citric acid is one of the important raw materials for the production of polycarbonate, super absorbent Polymers, zeolite, epoxy resin, sodium phosphate, sodium sulfite and a large number of sodium salts.
2. Different chemical properties
Citric Acid Mondydrate has the danger of combustion and explosion when it meets open fire, high heat or contact with oxidizing agent, while anhydrous citric acid has weathering in dry air, deliquescence in moist air, and water and carbon dioxide are liberated above 175℃.
3. Different molecular weight
The molecular weight of citric acid monohydrate is 581, while the molecular weight of citric acid anhydrous is 420.
4. Different physical properties
The relative density of citric acid monohydrate is 1.542, melting point is 153℃, refractive index is 1.493~1.509, and the critical temperature of solution crystallization is 36.6℃. And anhydrous citric acid properties: density 1.54, melting point 135-152 ℃, flash point 173.9 ℃, water solubility 1630 g / L .
Company information
The company's main import and export products include
(1)Rubber Products:Rubber is a hot-soluble thermosetting elastomer, while plastics are hot-soluble cold-setting. Rubber because of the different types of vulcanizate body, its molding and curing temperature range, there is a considerable difference, and even due to climate change, indoor temperature and humidity affected. Therefore, the production conditions of rubber products need to be adjusted moderately at any time, if not, it may produce differences in product quality.
(2)Intermediates：A material produced in an API process step that must undergo further molecular changes or refinement to become an API. Intermediates may or may not be separated.Our Intermediate products include Pharmaceutical Intermediates, Pesticide Intermediates and Dye Intermediates.
