Experimental and theoretical thermodynamic properties of RS-(±)- and S-(+)-mandelic acids

Thermal Effects Connected to Crystallization Dynamics: A Lattice Boltzmann Study

“…The physical parameters of the pure (S)-mandelic acid at temperature 𝑇 = 298.15 K (or 25 • C) are listed in Table 1. The enthalpy of crystallization 𝛥𝐻 𝑐𝑟𝑦𝑠𝑡 characterizes the energy difference per mole of S-ma between the solid and liquid(melt) phase and is represented here as negative value of the enthalpy of fusion (Emelýanenko et al, 2018). The value of specific heat capacity 𝑐 𝑝,𝐿 is that of water (being by far the dominating component) and 𝑐 𝑝,𝑆 is for racemic MA (Sapoundjiev et al, 2005).…”

“…It is also used for the further organic synthesis of pharmaceuticals, such as esters of mandelic acid generating homatropine for eye drops. Mandelic acid is well known for its antiaging effects on the skin along with antibacterial functions in treating acne (Emelýanenko et al, 2018). Furthermore, the manufacture of many rubbers, adhesives, and plastic materials requires mandelic acid as an intermediate substance.…”

“…It also shows activity against Gram-positive bacteria (Listeria monocytogenes and Staphylococcus aureus) and Gram-negative bacteria (Klebsiella pneumoniae and Pseudomonas aeruginosa) [ 7 ]. MA is a raw material developed in the production of polymers and rubber [ 8 ]. It also serves as a biomarker of exposure to styrene.…”
