Alcohol Manufacture from Potato. (VII)

Practical chiral alcohol manufacture using ketoreductases.

Over the past two years the application of ketoreductases in the commercial synthesis of chiral alcohols has undergone a revolution. Biocatalysts are now often the preferred catalyst for the synthesis of chiral alcohols via ketone reduction and are displacing reagents and chemocatalysts that only recently were considered break-through process solutions themselves. Tailor-made enzymes can now be...

Isopropyl Alcohol Manufacture by the Strong-acid Process

Isopropyl alcohol has been called the first petrochemical (IARC, 1992). It can be prepared via three different methods: indirect hydration of propylene, direct hydration of propylene, and catalytic hydrogenation of acetone. Indirect hydration, also called the sulfuric-acid process, was the only method used to produce isopropanol worldwide until the first commercial direct-hydration process was ...

Nucleotide sequence of two potato alcohol dehydrogenase cDNAs.

We have isolated two cDNA clones for potato {Solatium tuberosum L. cv. Kennebec) alcohol dehydrogenase (ADH, EC. 1.1.1.1) from a tuber cDNA library (1). Each clone encodes a polypeptide of 380 amino acids that differ at only one position (amino acid 5). The nucleotide sequences show 96% identity These two sequences are highly similar with the sequence of another potato ADH cDNA clone (1) and th...

Wastes from Manufacture of Dyes and Pigments

A preliminary study of the manufacture of dyes and pigments was conducted to determine if process waste streams might contain hazardous material. The study first identifies the dyes and pigments that belong to the major segments of the industry, the amounts produced, and the known U.S. producers. The chemistry of these dyes and pigments is discussed as well as the overall production process and...
