2 Current Scenario Usage of Solvents Pharmaceuticals 5% 22 MIO TONNES Research & Academia 20% Chemical & Painting 10% Others 27% Printing ink 8% Pharmaceutical Solvent 70% Challenges. Paints and Coating Toxic & hazardous 40% Increased chemical waste Contribute to increased CO2 Emission Chemicals have immediate, acute & chronic effect Green Solvents merck Metal cleaning/industrial cleaning 10% Adhesives 10%

3 Greener Solvent Principles of green chemistry Prevent waste Choose safer reagents Use renewable raw materials Avoid toxicity use synthetic methods Minimize energy and ressources Minimize effects on air and water Green Solvents merck

4 Greener Solvent Alternatives What does that mean for us Focus on synthetic methods Reduce toxicity for user and environment Use renewable raw materials Use products which do not persist in environment Offer less toxic reagents Green Solvents merck

5 Greener Solvent Alternatives We are already on the green way. Our Greener Solvent Alternatives offer you one or more of the following features and benefits: 2-Methyl tetrahydrofuran (Methyl THF) Less toxic and less hazardous Alternative to Dichloromethane (acc. and to THF CLP regulation) Derived from renewable resources Quick such drying & easy to recycle as corncobs and sugar cane bagasse Higher biodegradability (acc. OECD) Reduced chemical waste Cyclopentyl methyl ether (CPME) Ethyl lactate Higher boiling point compared to Alternative to THF, tert-butyl conventional methyl solvents ether, 1,4 Dioxane or other ether solvents Less volatile Economical 100 % atomic catalytical reaction (no waste) with high recovery rate Reduction of solvent loss Improves laboratory safety due to resistance of peroxide formation Contribution to reduction of energy and CO2 emissions Alternative to Ethylacetate & Acetone Ester of natural L-Lactic acid, which is produced by fermentation of sugar Green Solvents merck

6 Green Solvent Application 1 2-Methyl Tetrahydrofuran 2 Cyclopentyl methyl ether (CPME) 3 Ethyl lactate Alternative to Tetrahydrofuran for organomatellic reaction Grignard reaction Reformatskii Lithiation Hydride reduction Metal-Catalyzed coupling (Heck,Stille,Suzuki) Alternative to Dichloromethane for biphasic reactions Alkylation Amidation Alternative to 1,4-Dioxane, TBME Asymmetric Michael alkylation Glycosidation Debenzylation Reaction of ketone using NaBH4 Formation of sodium dispersion Alternative to Ethyl acetate, Acetone Coating industry (wood, polystyrene & metals) Cleaner for polyurethane industry Green Solvents merck

7 In 1668, Friedrich Jacob Merck purchased the Angel Pharmacy (Engel-Apotheke) in Darmstadt, which would become the historic core of the company. This makes Merck the world s oldest pharmaceutical and chemical company. The Angel Pharmacy exists to this day and is a state-of-the-art pharmacy that is still owned by the Merck family A NEW HORIZON

8 What we do Healthcare Prescription medicines to treat, for example, cancer, multiple sclerosis and infertility, over-the-counter pharmaceuticals for everyday health protection or to provide fast relief of colds and pain, as well as innovations in the areas of allergies and biosimilars. Life Science Innovative tools and laboratory supplies for the life science industry that make research and biotech production easier, faster and more successful. Performance Materials A wide range of specialty chemicals, such as liquid crystals for displays, effect pigments for coatings and cosmetics, or high-tech materials for the electronics industry.

9 Life Science leader is creating value responsibly Increase Product Sustainabilit y Minimize Impacts Mobilize Employees 10% Sustainable Product Families 10% Resource Reduction (GHGs, Water, Waste) 3 New Awareness Programs

10 20% LESS BY 2020 Climate protection concerns each and every one of us. We have therefore set ourselves the goal of reducing our greenhouse gas emissions by 20% by To reduce our CO 2 emissions, we are implementing the Group-wide EDISON program to improve our energy efficiency and our processes.

11 In the region around our site in Goa, India cashews and coconuts are grown, the shells of which are left as waste after being harvested. We are building a biomass power plant that will use these shells as fuel. Starting in 2015, we will thus save around 11,000 metric tons of carbon dioxide per year. On top of that, our site will operate independently of the public power grid and be completely carbon neutral. ENERGY FROM A NUT
