Syngas route to adipic acid
In an era of escalating hydrocarbon prices, the development of new technology to synthesize large volume chemical intermediates from the least expensive sources of carbon and hydrogen has been a research area of increasing intensity. Adipic acid is prepared commercially by oxidative processes using either benzene or phenol as the raw material base. Since both benzene and phenol prices track with the price of crude oil, future adipic acid price will increase as the oil reserve decreases. Thus, there is a need for a new process to produce adipic acid from cheap, and readily available, raw materials such as butadiene obtained as a by-product from world scale olefin plants. One such process that capitalizes on the use of butadiene as a raw material is BASF's two-step carbonylation route to adipic acid. The butadiene in the C/sub 4/ cut from a steam cracker is transformed by a two-stage carbonylation with carbon monoxide and methanol into adipic acid dimethyl ester. Hydrolysis converts the ester into adipic acid. BASF is now engineering a 130 mm pound per year commercial plant based on this technology.
