meso-Lactide

Description:

Meso-Lactide, with the CAS number 13076-19-2, is a cyclic diester derived from lactic acid, specifically a stereoisomer of lactide. It is characterized by its unique structure, which features a symmetrical arrangement of its chiral centers, leading to its designation as "meso." This symmetry results in a lack of optical activity, distinguishing it from its enantiomeric counterparts. Meso-Lactide is typically a white crystalline solid and is soluble in organic solvents such as chloroform and acetone, but less soluble in water. It is primarily used in the production of biodegradable polymers, particularly polylactic acid (PLA), which has applications in medical devices, packaging, and environmentally friendly materials. The polymerization of meso-Lactide can be initiated through various methods, including ring-opening polymerization, making it a valuable compound in materials science. Additionally, its biodegradability and biocompatibility make it an attractive option for sustainable development in various industries.

meso-Lactide

CAS: 13076-19-2

Meso-Lactide is a polymerized mesophase that has been shown to be crystallizable. It consists of a mixture of monomers and impurities. The nucleophilic attack on the meso-lactide monomer by the stannous octoate initiates the ring-opening polymerization process, which leads to a change in morphology from a lamellar phase to a crystalline phase. The growth kinetics of meso-lactide have been determined at constant temperature in order to better understand the crystallization process. Microscopy studies have also been conducted in order to observe the changes in morphology during different stages of crystallization.
