Yusof, Separation of CO2 from CH4 by pure PSF and PSF/PVP blend membranes: Effects of type of nonsolvent
, solvent, and PVP concentration, J.
About 0.32 wt% of ethyl cellulose as a suspending stabilizer was dissolved in nonsolvent
(cyclohexane: 1, 2-dicloroethane = 8:7, density = 1.0) and this phase was heated to 65[degrees]C in the reactor stirred at 150 rpm.
The reasons are as follows: on one hand, according to the bonding mechanism  and in the process of HMX recrystallization refinement, before entering the nonsolvent
, HMX molecules have a greater degree of collision with high-speed moving water vapor molecules.
Although PVDF poses a relatively low surface energy, a phase-inverted one from a strong nonsolvent
(i.e., water) usually has low hydrophobicity .
The morphology and drug dispersion of crystallized mannitol particles (CMP) were mainly reliant on the proportion water in nonsolvent
and crystallization technique employed .
This solution is brought into contact with a different solvent (called nonsolvent
), in which the polymer is insoluble.
The obtained copolymers were purified by reprecipitation using acetone as a nonsolvent
and then dried under vacuum.
The addition of filler would cause the binodal line occurring at lower nonsolvent
concentration which reduced the required nonsolvent
for separation of dope solution.
When checking other CPEs rather than solvent types such as ethanol, skin impedance may be dependent on the penetration-enhancing effect, because little contribution is expected by nonsolvent
type enhancers on the thermodynamic activity of penetrants.
As a nonsolvent
, it also has a lower dielectric point than water, increasing the protein-protein attraction forces.
The choice of ethanol was caused by its being a nonsolvent
(precipitant) for chitosan and silicon glycerohydrogel but a solvent for water, glycolic acid, and glycerol.
"At Emerald, we have made significant investments in expanding our development capabilities in order to be able to introduce new products that balance desirable performance properties with economy and sustainability, including products that are low- or zero-VOC, 100% solids nonsolvent
options, and solutions that maximize compatibility for lower emissions," she says.
