⚗️ Chemical & Physical Properties
D-Lactic acid typically appears as a colorless or slightly yellow liquid with a slightly sour odor reminiscent of vinegar. It is a naturally occurring organic compound that can be found in various fermented food products.
D-Lactic acid has a molar mass of approximately 90.08 g/mol and a density of about 1.213 g/cm³ at room temperature. In comparison to common food items, D-Lactic acid has a relatively low molar mass and density, making it a lightweight and less dense molecule.
The melting point of D-Lactic acid is around 40-45°C, while the boiling point is approximately 122-124°C. These values are relatively low compared to common food items, which often have higher melting and boiling points due to their complex molecular structures.
D-Lactic acid is highly soluble in water, forming a clear and colorless solution. It also exhibits a low viscosity, allowing it to easily dissolve and mix with other substances. Compared to common food items, D-Lactic acid has good solubility in water and low viscosity, making it an ideal ingredient for various food and beverage applications.
🏭 Production & Procurement
D-Lactic acid is primarily produced through bacterial fermentation processes, with strains such as Lactobacillus spp. or genetically engineered Escherichia coli being commonly used. These microbes transform sugars like glucose or starch into D-Lactic acid through metabolic pathways, such as the glycolytic or pentose phosphate pathway.
Procurement of D-Lactic acid typically involves purification processes after fermentation, where the crude product is separated from the bacterial cells and other impurities. Techniques such as filtration, distillation, or crystallization are employed to isolate and purify the D-Lactic acid before it can be used in various industrial applications.
Once procured, D-Lactic acid can be transported in liquid form in specialized containers, such as drums or tanks, to ensure its stability and prevent contamination. It is important to maintain proper temperature and storage conditions during transportation to prevent degradation and maintain the quality of the product for its intended use.
⚠️ Safety Considerations
Safety considerations for D-Lactic acid involve its potential hazards and proper handling to minimize risks. D-Lactic acid may cause eye and skin irritation upon contact, and inhalation of its vapors can result in respiratory irritation. It is important to use appropriate personal protective equipment such as gloves, goggles, and respirators when working with D-Lactic acid to prevent exposure.
Hazard statements for D-Lactic acid include its ability to cause skin and eye irritation, as well as respiratory irritation if inhaled. It is advised to avoid direct contact with the substance and ensure adequate ventilation when handling D-Lactic acid to prevent any adverse effects. In case of exposure, immediate medical attention should be sought to avoid further complications.
Precautionary statements for D-Lactic acid include the need to wear suitable protective clothing, gloves, and eye/face protection when handling the substance. It is important to work in a well-ventilated area to avoid inhaling vapors or mist. In case of accidental exposure, rinse affected areas with plenty of water and seek medical advice if symptoms persist. Storage of D-Lactic acid should be in a cool, dry place away from incompatible materials to prevent any potential hazards.
