A new crossover sine model based on trigonometric model and its application to the crossover lattice equation of state.

In this study, a new crossover sine model (CSM) n was developed from a trigonometric model [M. E. Fisher, S.

Preparation of cefpodoxime proxetil fine particles using supercritical fluids.

Fine particles of cefpodoxime proxetil (CPD) were prepared using an Aerosol Solvent Extraction System (ASES) with supercritical CO(2). The resulting primary particles were approximately 0.1-0.

Cyclopolymerization of dimethyl dipropargylmalonate in supercritical carbon dioxide to give a highly regular polyene containing predominantly five-membered rings.

Poly(dimethyl dipropargylmalonate) synthesized in scCO2 contained more than 95% five-membered rings, i.e., highly regular polyene was produced, which shows carbon dioxide as a reaction medium plays a significant role in determining a highly selective polymer structure.
