This study investigates the solubility of Baclofen in supercritical CO2, which is essential for developing an efficient drug delivery system using processes. Solubility measurements were carried out both with and without presence various cosolvents (ethanol dimethyl sulfoxide (DMSO)), across a temperature range 308–338 K pressure 12–30 MPa. exhibited ranging from 1.62 × 10–5 to 2.30 mole fractions pure CO2. In cosolvents, increased 5.76 12.79 ethanol 3.50 7.02 DMSO. Indeed, addition DMSO by approximately 3.55–5.56 times 2.15–3.05 times, respectively. Several density-based empirical models thermodynamic (Soave–Redlich–Kwong (SRK) Peng–Robinson (PR) equations state) used correlate data. Jafari Nejad's model CO2–Baclofen Jouyban's CO2–ethanol/DMSO–Baclofen systems displayed higher consistency. Also, PR showed better accuracy correlating while SRK outperformed CO2–ethanol/DMSO cosolvents. Moreover, machine learning exceptional accuracy, over 99% predictions closely matching experimental data, emphasizing its outstanding performance.

In order to develop supercritical fluid (SCF) processes for the micro or nanosizing of solid solute components, such as pharmaceuticals, it is essential assess their solubility in solvents including carbon dioxide (SC–CO2). This crucial step fundamental choosing and evaluating SCF technology. A statistical method was developed used determine gemcitabine SC-CO2. The measurements at various pressures temperatures were conducted using UV–vis analysis. Two model types correlate data: semi-empirical (with 3–6 parameters) equation state (EoS) models. SC-CO2 a static 308–338 K 120–270 bar measured modeled first time. Solubility ranged from 0.1274 × 10− 5 1.8128 mole fraction 0.00295 0.08489 kg/L.

Supercritical carbon dioxide (scCO2) plays an essential role in various technological procedures, making the solubility of drugs scCO2 a crucial aspect drug formulation process. This study focuses on utilizing theoretical approaches to predict drug-like compounds order select optimum parameters for subsequent experimental procedures. Several machine learning models were developed and compared with previously established approach based classical density functional theory (cDFT). The CatBoost model, alvaDesc descriptors, demonstrated reasonably accurate predictions 187 (AARD = 1.8%). Meanwhile, incorporating CDK descriptors melting points as input parameters, exhibited satisfactory accuracy 14.3%) extrapolating new compounds. Comparing results between cDFT-based one revealed, average, higher faster prediction speed former. However, cDFT more physical behavior isotherms models. was particularly evident when ML struggled accurately extrapolate values beyond range supercritical state.
