4 huntsman corporation is the The JEFFSOL Carbonates can be world's largest producer of used as "safe" and Alkylene Carbonates . At a environmentally friendly solvents production capacity of 65 million replacing harsh products such as pounds per year, huntsman can methylene chloride, acetone, produce about 50% of the world's aromatic solvents, and other Carbonates . highly volatile and hazardous solvents. The roots of huntsman 's Carbonates experience date back Carbonates can also be used as to the 1950's; however, in 1996, reactive intermediates replacing the company brought on stream ethylene and propylene oxides the first "large" scale plant in the and ethylene and propylene world.

5 Glycols in many reactions. huntsman produces its Where substitution occurs, use of Carbonates in three separate the Carbonates may allow for a manufacturing facilities on two more selective reaction and continents and maintains bulk minimizes side reactions and storage of these materials in contaminants. various sites around the world. In many cases, our technical staff In addition to JEFFSOL Ethylene will assist our customers in Carbonate (EC), JEFFSOL formulations, carbonate Propylene Carbonate (PC) and reactions, and development of JEFFSOL Butylene Carbonate specialized products.

6 (BC), the group produces a series of UltraPure Carbonates and is continuing to invest in specialty Carbonates and carbamates. huntsman is dedicated to developing the latest production technology and specialized derivatives for use in a variety of markets. 1. huntsman JEFFSOL Carbonates .. The JEFFSOL Carbonates are cyclic All JEFFSOL Carbonate products organic esters made from the are clear in appearance. reaction of ethylene oxide, propylene or butylene oxide with The JEFFSOL Carbonates have carbon dioxide. found use in numerous applications that require Our core products are JEFFSOL outstanding solvency combined Ethylene Carbonate, Propylene with high flash points, low Carbonate, and Butylene evaporation rates, low VOCs, and Carbonate (see structures below).

7 Low toxicity. In addition, these molecules can be used as reactive Blends of JEFFSOL Ethylene intermediates. Carbonate and Propylene Carbonate are also available. They produce a variety of commercially important chemicals These blends may be used where and derivatives through liquid products are required. chemistries such as (Note JEFFSOL Ethylene hydroxyalkylation, Carbonate is solid at room transesterification, and carbamate temperature.) formation. JEFFSOL EC-75, EC-50 and EC-25. are blends of JEFFSOL Ethylene Carbonate and Propylene Carbonate in the ratios of 75/25, 50/50 and 25/75 by weight, respectively.
