⚗️ Chemical & Physical Properties
Galactaric acid is a colorless crystalline solid with no distinct odor. Its appearance is akin to that of sugar or salt crystals.
The molar mass of galactaric acid is 194.13 g/mol, with a density of approximately 1.61 g/cm^3. In comparison to common food items, this molecular weight is higher than glucose (180.16 g/mol) but lower than sucrose (342.3 g/mol), while its density is similar to that of table salt (NaCl).
Galactaric acid possesses a melting point of around 221-223 °C and a boiling point of 330-335 °C. These values are significantly higher than those of common food items like sugar (melting point of 160-186 °C; boiling point of 320 °C) and salt (melting point of 801 °C; boiling point of 1465 °C).
The solubility of galactaric acid in water is limited, as it is only slightly soluble. It also exhibits a high viscosity when dissolved. In comparison, common food items like sugar and salt are highly soluble in water and have lower viscosities.
🏭 Production & Procurement
Galactaric acid is a compound that can be produced through biotechnological processes, typically involving the fermentation of carbohydrates. This process often utilizes genetically modified microorganisms to convert substrates into Galactaric acid through a series of enzymatic reactions.
To procure Galactaric acid, industrial-scale production facilities are typically utilized to optimize the fermentation process. Once the Galactaric acid is produced, it can be further purified and concentrated through various methods such as crystallization or chromatography. The final product is then packaged and transported to customers for further applications.
Transportation of Galactaric acid is typically done in liquid form, using specialized tanker trucks or containers. The acid is often sensitive to temperature and pH changes, requiring careful handling during transportation to maintain its stability. Upon arrival at its destination, Galactaric acid is typically stored in designated areas that meet specific safety requirements to ensure its integrity.
