Abstract
In one aspect, the invention relates to filter apparatuses useful as sampling media and stabilizing pharmaceutical compounds, methods of making same, compositions useful for stabilizing pharmaceutical compounds, and methods of isolating pharmaceutical compounds from an air stream using the apparatuses and compositions. This abstract is intended to be used as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
Claims20
A filtration apparatus comprising:
- (a) a composition of an ionic liquid iodide and an antioxidant selected from ascorbic acid (Vitamin C), adipic acid, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), citric acid, fumaric acid, glutamic acid, malic acid, propyl gallate, sulfurous acid, tartaric acid, tocopherol (Vitamin E), thiols, and derivatives and salts thereof;
- and
- (b) a hydrophilic filter membrane.
A process for making a filtration apparatus, the method comprising the steps of:
- (a) mixing a low boiling solvent, an ionic liquid iodide, and an antioxidant selected from ascorbic acid (Vitamin C), adipic acid, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), citric acid, fumaric acid, glutamic acid, malic acid, propyl gallate, sulfurous acid, tartaric acid, tocopherol (Vitamin E), thiols, and derivatives and salts thereof;
- (b) applying the mixture to a hydrophilic filter membrane;
- and
- (c) forming a gel from the mixture on the membrane by removing at least a portion of the solvent.
A composition comprising a gel formed from methyl propylimidazolium iodide (MPII) and an antioxidant selected from ascorbic acid (Vitamin C), adipic acid, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), citric acid, fumaric acid, glutamic acid, malic acid, propyl gallate, sulfurous acid, tartaric acid, tocopherol (Vitamin E), thiols, and derivatives and salts thereof.
