Eastman's Custom Processing Plan for commercial-scale organic reactions
Eastman is performing a wide range of commercial organic r e a c tions o n a contract basis for companies seeking to postpone o r avoid n e w capital investment o r timeconsuming process development. Some of t h e products are intermediates for further processing by the contracting company. Some a r e finished chemicals ready for marketing.
