  日期：——

  2-Octylsuccinic acid and its copolyanhydrides with sebacic acid have been synthesized by melt polycondensation, and were characterized by Fourier transform infrared spectroscopy, 1H NMR, gel permeation chromatography, differential scanning calorimetry, and thermal gravimetric analysis. In vitro studies showed that all copolymers are degradable in phosphate buffer at 37°C. The release profiles of the hydrophilic model drug ciprofloxacin hydrochloride follow first-order release kinetics.

  This disclosure provides a process for producing vinylidene dimer derivatives by subjecting one or more vinylidene dimers and one or more carbonyl-containing compounds to a carbonyl-ene reaction, optionally in the presence of a catalyst, to produce one or more vinylidene dimer derived alcohols. This disclosure also provides a process for producing vinylidene dimer derivatives by reacting one or more vinylidene dimers with one or more carbonyl-containing compounds, optionally in the presence of a catalyst, to produce one or more vinylidene dimer derived alcohols. This disclosure further provides vinylidene dimer derivatives (e.g., vinylidene dimer derived alcohols and esters) produced by these processes. This disclosure still further provides for hydrogenating/reacting the vinylidene dimer derived alcohols with acids or anhydrides to produce vinylidene dimer derived esters. This disclosure yet further relates to lubricating ester oil base stocks, and lubricating oils containing the lubricating ester oil base stocks.

  It is intended to provide a composition containing isoflavones which has a high purity and yet is highly soluble in water in a natural state without adding any solubilizers or subjecting to chemically modification. It is found out that a composition containing isoflavones with a high purity and a high solubility in water can be obtained by extracting soybean hypocotyls with a water-containing alcohol within a specific temperature range, then allowing a synthetic adsorbent resin to adsorb the obtained extract and eluting with a water-containing alcohol at a specific concentration.

  Additive manufacturing powder contains a core-shell type particle containing a core particle comprising a first binder resin and a filler and a shell present on the surface of the core particle. The shell contains a second binder resin. The powder has a particle size distribution Dv/Dn of 1.5 or less and an average circularity of from 0.800 to 0.980, the average circularity being represented by the following relation: Average circularity=(a perimeter of a circle having the same area as a projected image of a particle)/(the perimeter of the projected image of the particle)×100.
