A simpler and more-efficient way to obtain purified terephthalic acid (PTA) has been developed by GTC Technology (Houston, Tex.; edlinks.che.com/6895-537). In conventional PTA production, p-xylene is oxidized to crude terephthalic acid (CTA), then purified by hydrogenation in an aqueous solution. Hydrogenation converts the main impurity, 4-carboxybenzaldehyde (4-CBA), to p-toluic acid, which is more readily...

In order to produce ethanol with nearly 100% purity from fermentation broth, conventional processes use a two-step distillation operation, which accounts for almost 55% of the total energy requirements. Therefore, improving the concentration step is a key to reducing the costs of making bioethanol. A promising step in this direction is a new gating membrane being developed by professor Shin-ichi Nakao at...
