    Abstract: A system for the controlled addition of detergent formulations and the like to a carbon dioxide cleaning apparatus comprises: (a) a high pressure wash vessel; (b) an auxiliary vessel; (c) a drain line connecting the auxiliary vessel to the wash vessel; (d) optionally but preferably, a separate vent line connecting the auxiliary vessel to the wash vessel; (e) a detergent reservoir; and (f) a detergent supply line connecting the detergent reservoir to the auxiliary vessel. An advantage of this apparatus is that, because the detergent formulation can be pumped into the auxiliary vessel in a predetermined aliquot or amount, which predetermined aliquot or amount can then be transferred into the wash vessel where it combines with the liquid carbon dioxide cleaning solution, the detergent formulation can be added to the cleaning solution in a more controlled or accurate manner. An alternate embodiment adapted for the addition of aqueous detergent formulations and the like to a carbon dioxide dry cleaning system under turbulent conditions comprises: (a) a high pressure wash vessel; (b) a filter; (c) a carbon dioxide cleaning solution drain line interconnecting the wash vessel to the filter; (d) a carbon dioxide cleaning solution supply line connecting the filter to the wash vessel; (e) a first high pressure pump (i.e., a pump that is capable of pumping liquid solutions comprising liquid carbon dioxide) operably connected to the drain line; (f) a detergent formulation reservoir; (g) a detergent formulation supply line connecting the reservoir to the carbon dioxide cleaning solution supply line; and (h) a second high pressure pump operably connected to the detergent formulation supply line for transferring detergent formulation from the detergent formulation reservoir into the carbon dioxide cleaning solution under turbulent conditions.

    Abstract: A method for dry-cleaning articles such as fabrics and clothing in carbon dioxide comprises contacting an article to be cleaned with a liquid dry cleaning composition for a time sufficient to clean the fabric. The liquid drycleaning composition comprises a mixture of carbon dioxide, water, a surfactant, and an organic co-solvent. After the contacting step, the article is separated from the liquid dry cleaning composition. The method is preferably carried out at ambient temperature. The surfactant is preferably one that does not contain a CO2-philic group. The organic co-solvent is preferably an alkane and has a flash point above 140 ~F.

    Abstract: A method of coating a substrate comprises the steps of: (a) providing a substrate in an enclosed vessel, the substrate having a surface portion; (b) at least partially filling the enclosed vessel with a first supercritical fluid so that said first supercritical fluid contacts the surface portion, with the first supercritical fluid carrying or containing a coating component; then (c) adding a separate compressed gas atmosphere to the reaction vessel so that a boundary is formed between the first supercritical fluid and the separate compressed gas atmosphere, said separate compressed gas atmosphere having a density less than said first supercritical fluid; and then (d) displacing said first supercritical fluid from said vessel by continuing adding said separate compressed gas atmosphere to said vessel so that said boundary moves across said surface portion and a thin film of coating component is deposited on said microelectronic substrate.
