The crystal growth kinetics of two different polymorphs of Piracetam have been investigated in ethanol and isopropanol. Isothermal seeded desupersaturation experiments were carried out at supersaturation ratios below 1.2 within the range of temperature 283–308 K. Liquid concentration was determined by in situ ATR-FTIR spectroscopy by a calibration-free method using principal component analysis. The power law equation and the BCF and B+S models were fitted to the experimental desupersaturation data by nonlinear optimization. The growth rates ranged 10–7–10–8 m/s, the growth rate order is clearly higher than unity, and the activation energies are in the range 39–66 kJ/mol for all the systems studied suggesting surface integration control. The growth of the metastable polymorph is faster than that of the stable form in both solvents. The crystal growth proceeds faster in ethanol than in isopropanol for both polymorphs. The solid–liquid interfacial energy is lower for the metastable form and is for both forms lower in ethanol than in isopropanol. The surface diffusion mass transfer rate is higher for the metastable form compared to the stable form and higher in ethanol than in isopropanol.

The simultaneous liquid-phase synthesis of 2-ethoxy-2-methylpropane (ETBE) and 2-ethoxy-2-methylbutane (TAEE) has been studied over fifteen commercial acidic ion-exchange resins. Kinetic experiments were carried out in a batch reactor at T = 335 K and initial molar ratios of alcohol to olefins (R°A/O) and between olefins (R°C4/C5) of 1.1 and 1, respectively. The catalytic activity, measured as intrinsic initial etherification rates, has been found to decrease in the order: Amberlyst™ 35 > Amberlyst™ 48 > Purolite® CT-275 > Amberlyst™ 15 > Purolite® CT-175 > Amberlyst™ 40 > Amberlyst™ 36 > Amberlyst™ 16 > Purolite® CT-482 > Amberlyst™ 39 > Amberlyst™ DT > Amberlyst™ 45 > Purolite® CT-124 > Purolite® MN-500 > Amberlyst™ 46. This catalytic activity rank is related to the morphological properties of the resins in both dry and swollen states. The ratio of acid capacity to specific volume of the swollen polymer has been found to be the main catalyst properties that determine their activity: the higher the ratio, the higher the activity.
