[A generator for producing multicomponent organic solvent vapor in inhalation chambers].

A vapor generator for multicomponent organic solvents was developed and its performance was investigated experimentally. The vapors were generated from the surface of a sintered sphere of glass beads containing the organic solvents. The solvents were automatically supplied from the solvent reservoir to the sphere by suction pressure caused by the evaporation of the solvents and the generated va...

Solvent reorganisation as the driving force for rate changes of Menschutkin reactions in an ionic liquid.

The effect on the rate of reaction of each of a series of Menschutkin processes on changing from a molecular solvent to an ionic liquid was investigated. In each case, the rate acceleration observed at room temperature could be attributed to the change in the entropy of the system on reaching the transition state, offsetting any enthalpic cost.

Fabrication of Janus particles composed of poly (lactic-co-glycolic) acid and hard fat using a solvent evaporation method.

The feasibility of fabricating Janus particles based on phase separation between a hard fat and a biocompatible polymer was investigated. The solvent evaporation method used involved preparing an oil-in-water (o/w) emulsion with a mixture of poly (lactic-co-glycolic) acid (PLGA), hard fat, and an organic solvent as the oil phase and a polyvinyl alcohol aqueous solution as the water phase. The J...
