The document discusses green solvents and ionic liquids as alternatives to traditional water-based cleaning formulations. It introduces Waterless Cleaning LLC, which aims to license green solvent formulations and sell ionic liquids. Their primary project is developing a waterless laundry cleaning system using green solvents and ionic liquids. Theoretical cost comparisons for a local hotel suggest the solvent system could cost less than their current water-based system after the first month. Benefits of the solvent system include energy and water efficiency, recycling of solvents, and equal or better cleaning performance compared to water.

ILs is a group of new organic salts that exist in the liquid state at relatively low temperatures. Ionic liquids have different properties than solid ionic compounds. Besides of these unique properties, ionic liquids have a number of useful applications.
water can be consider as a potentially green solvent.it is safest & least expensive solvent. organic reaction in aqueous medium.like deals alder reaction,pinacol coupling.
Digital Library of GLT SBM, DL of GLT SBM Green Chemistry is the utilization of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products.
Green Chemistry is about:
1. Waste minimization of source
2. Use of catalysts in place of reagents
3. Using non-toxic reagents
4. Use of renewable resources
5. Improved atom efficiency
Ionic liquids are excellent substitutes for traditional organic solvents in many typical organic reactions, often producing higher selectivity as well as higher yields, and enhancing the reaction rate.
Additionally, they can serve as catalyst immobilization for the easy recycling of homogeneous catalysts without need for special functionalization, and have been successfully employed as electrolytes in electrochemistry. "Tailor-made" solvents (optimization of the ionic liquid's characteristics) can be achieved through a broad choice of anion and cation combinations. Ionic liquids are attractive solvents as they are non-volatile, non-flammable, have a high thermal stability and are relatively inexpensive to manufacture. They usually exist as liquids well below room temperature up to a temperature as high as 200oC.
The key point about ionic liquids is that they are liquid salts, which means they consist of a salt that exists in the liquid phase. They are not simply salts dissolved in liquid. Usually one or both of the ions is particularly large and the cation has a low degree of symmetry, these factors result in ionic liquids having a reduced lattice energy and hence lower melting points.Many ionic liquids have even been developed for specific synthetic problems. For this reason, ionic liquids have been termed "designer solvents".

cost into cleaning/other markets.
May 18, 2010
3. Green Solvents and Ionic Liquids
What are “Green” Solvents ?
(for our applications)
• Not halogenated, non-flammable (< 100 0C), non-hazardous, non-toxic
• Low /no VOC
• BP < 200 0C
• Biodegradable, stable, recyclable
• Low water solubility (< 5 wt% in solvent)
Best choices are solvents derived from bio-diesel, plant, natural products
May 18, 2010
4. Green Solvents and Ionic Liquids
Choosing the Right Green Solvent(s)
Considerations
• Low pricing (< $ 1.50/lb)
• World-wide availability, high volume potential
• Safe for people /environment
• Low /no VOC
• Compatibilities (w/equipment /materials to be cleaned)
• Equipment design
• Examples – dibasic esters, lactates, soy-based, Si-based, others
May 18, 2010
5. Green Solvents and Ionic Liquids
What are Ionic Liquids (ILS) ?
Our ILs are:
• Combinations of cations(+) and anions(-)
• Liquids (viscous) at room temperature (RTILs)
• Cross between “Green” solvents and surfactants
• Hydrophobic, non-halogenated, no unusual cyclic structures,
conductive, simple
• Less expensive (ours < $1/gm, others > $100/gm)
May 18, 2010
6. Green Solvents and Ionic Liquids
Applications for Ionic Liquids
• Solvents for pharmaceutical manufacturing
• Lubricants
• Extending the life of a lithium battery
• Dispersants in paints
• Solar energy (heat transfer and storage medium)

May 18, 2010
7. Green Solvents and Ionic Liquids
Primary Project
To develop a revolutionary change in the cleaning of fabrics by
combining dry cleaning concepts and water-based laundry systems into
a green and sustainable laundry system for institutional, industrial,
commercial, and consumer laundry operations (without using water)
This is a Disruptive Technology !
May 18, 2010
8. Green Solvents and Ionic Liquids
Laundry Cleaning Today
Follows the Energy Star program by minimizing:
• Water usages
• Energy consumption
• Chemical usage
• Overall costs
But, we still dump billions of gallons of water down the drain every
day (containing more detergent than contamination ) !
Is this a Sustainable Process ?
May 18, 2010
9. Green Solvents and Ionic Liquids
Is water, the Next Oil ?
• 3% of the Earth has drinkable water
• 1% of the 3% is accessible (rest is tied up in glaciers)
• 20% of the 1% is found in the Great Lakes Region (USA)
Ethical Challenge: We need to minimize our use of drinking water for
non-essential applications (i.e., laundry, dishwasher, toilets, watering
lawns, washing cars, etc). Our waste water streams are running on
maximum.
May 18, 2010
10. Green Solvents and Ionic Liquids
Laundry Cleaning Tomorrow
Moving towards Waterless (Dry) Cleaning
• Cold water cleaning w/minimal water and energy
