The phrase "a solvent propylene" is not correct in standard written English.
It may be intended to describe a type of propylene that acts as a solvent, but the phrasing is awkward and unclear.
Example: "In the chemical process, we utilized a solvent propylene to dissolve the compounds effectively."
Alternatives: "a propylene solvent" or "solvent-grade propylene".
But to clean, it uses a solvent, propylene glycol ether, rather than liquid carbon dioxide.
The SMBR operation is applied to an industrial case study for the continuous production of a solvent, propylene glycol methyl ether acetate (DOWANOL™ PMA), which is produced through an acid-catalyzed esterification reaction of 1-methoxy-2-propanol and acetic acid.
The drug within the liquisolid system is usually already dissolved in a nonvolatile solvent (propylene glycol, polyethylene glycol, glycerol, etc).
Conversely, all other compounds tested (i.e., octocrylene, ethylhexylsalicylate, and 4- tert-butyl-4-methoxydibenzoylmethane) and the solvent propylene glycol, which is also present in sunscreen formulations, had a minor effect or no effects when compared with controls (Table 1).
Preliminary studies of gel electrolytes based on PMMA and solutions of the lithium salt LiN CF3SO2 22 in propylene carbonate (PC) and the mixed solvent propylene carbonate+ethylene carbonate (PC+EC) are presented.
Solid electrolyte composed of silicate matrix solvated by tetraalkylammonium salt solution in viscous organic polar solvent (propylene carbonate or sulpholane) was prepared by sol gel method under controlled drying conditions.
Solid electrolyte composed of hybrid organic inorganic silicate matrix functionalised with tetraalkylammonium group, solvated by viscous organic polar solvent (propylene carbonate (PC) or sulpholane (TMS)), was prepared by the sol gel method under controlled drying conditions.
After developing in solvent (propylene glycol methyl ether acetate), all unexposed regions of the photoresist dissolved to give a silicon wafer that bore an array of three-dimensional features with the desired dimensions.
The UV filters ethylhexyl-methoxycinnamate (OMC), octocrylene (OCT), benzophenone-3 (BZ), ethylhexylsalicylate (EHS), and the solvent propylene glycol (PG) (Table 2) were purchased from Sigma-Aldrich Co. (Milan, Italy); 4- tert-butyl-4-methoxydibenzoylmethane was obtained in the form of Eusolex 9020 from Merck (Darmstadt, Germany).
A typical electrolyte might be lithium tetrafluoroborate salt in a solvent mixture of propylene carbonate, 2-methyl-2-oxazolidone, and dimethoxyethane.
Solutions of LiClO4, LiAsF6, and LiPF6 in the mixed solvents propylene carbonate+dimethoxyethane and ethylene carbonate+diethyl carbonate were used.
