Abstract
Chlorofluorocarbon replacement solvents include a main component (first solvent) and a property-modification component (second solvent). The resulting solvent mixtures meet or exceed the solvency, flammability, and compatibility requirements for CFC's while providing similar or improved environmental and toxicological properties. These solvent mixtures can be used in conjunction with refrigeration or heat pumps, electronics, implantable prosthetic devices, oxygen systems, and optical equipment.
Claims9
A solvent mixture comprising 60-99 wt. % of a main solvent and 1-40 wt. % of a property-modification solvent, wherein:
- the main solvent is d-limonene, and
- the property-modification solvent is isoflurane.
A method of cleaning and/or decreasing components for refrigeration systems, heat pumps or air conditioning units, comprising flushing the components with a solvent mixture consisting essentially of 66 wt. % d-limonene and 34 wt. % tetraglyme.
