Abstract

This article provides a comprehensive guide for beginners on CAS 10326-41-7 D-Lactic Acid. It delves into the properties, applications, production methods, safety considerations, and regulatory aspects of D-Lactic Acid, offering a detailed overview for those new to this chemical compound.

Introduction to D-Lactic Acid

D-Lactic Acid, with the CAS number 10326-41-7, is a chiral compound that is a key component in various industrial applications. It is a monomer of polylactic acid (PLA), which is widely used in biodegradable plastics, textiles, and pharmaceuticals. This guide aims to provide a foundational understanding of D-Lactic Acid, covering its characteristics, uses, and production processes.

Properties of D-Lactic Acid

D-Lactic Acid is a colorless, odorless solid that is soluble in water. It has a melting point of approximately 135°C and a boiling point of around 170°C. The compound is a hydroxy acid with the molecular formula C3H6O3. It exists in two enantiomeric forms, D-Lactic Acid being one of them. The other form, L-Lactic Acid, is the naturally occurring form in the body and is more commonly used in food applications.

Applications of D-Lactic Acid

D-Lactic Acid finds extensive use in various industries. One of the primary applications is in the production of polylactic acid (PLA), which is used to create biodegradable plastics. These plastics are gaining popularity due to their environmental benefits, as they can be composted and do not contribute to plastic pollution. D-Lactic Acid is also used in the pharmaceutical industry for the synthesis of drugs and as a preservative. Additionally, it is employed in the textile industry for dye fixation and as a softener.

Production Methods of D-Lactic Acid

The production of D-Lactic Acid involves several methods, including microbial fermentation and chemical synthesis. The most common method is microbial fermentation, where lactic acid bacteria convert glucose or other carbohydrates into lactic acid. This process is environmentally friendly and sustainable. Chemical synthesis, on the other hand, involves the conversion of other chemicals into lactic acid, which is less common due to higher energy consumption and environmental impact.

Safety Considerations for D-Lactic Acid

D-Lactic Acid is generally considered safe for use in industrial applications. However, it is important to handle it with care due to its potential to cause irritation to the skin, eyes, and respiratory system. Adequate ventilation and personal protective equipment should be used when working with D-Lactic Acid. It is also important to store it in a cool, dry place away from incompatible materials.

Regulatory Aspects of D-Lactic Acid

D-Lactic Acid is subject to various regulations depending on its intended use. In the European Union, it is classified as a food additive (E270) and is approved for use in food products. In the United States, it is also recognized as Generally Recognized as Safe (GRAS) for use in food. Additionally, regulations govern its use in pharmaceuticals and other industrial applications, ensuring its safety and quality.

Conclusion

CAS 10326-41-7 D-Lactic Acid is a versatile chemical compound with a wide range of applications. This comprehensive guide has covered its properties, uses, production methods, safety considerations, and regulatory aspects, providing a solid foundation for beginners. Understanding these aspects is crucial for anyone involved in the production, handling, or use of D-Lactic Acid, whether in industry, research, or consumer applications.
