Abstract: A compound having formula (Ph3C)mAr(OR)n, wherein Ph represents a phenyl group, Ar is an aromatic ring system having from six to twenty carbon atoms, R is C1-C18 alkyl or C7-C12 aralkyl, m is one or two, and n is an integer from one to four.
Abstract: Modification of the amino acid sequence of a phenylpyruvate decarboxylase from Azospirillum brasilense produces a novel group of phenylpyruvate decarboxylases with improved specificity to certain substrates, including in particular C7-C11 2-ketoacids such as, for example, 2-ketononanoate and 2-keto-octanoate. This specificity enables effective use of the phenylpyruvate decarboxylase in, for example, an in vivo process wherein 2-ketobutyrate or 2-ketoisovalerate are converted to C7-C11 2-ketoacids, and the novel phenylpyruvate decarboxylase converts the C7-C11 2-ketoacid to a C6-C10 aldehyde having one less carbon than the 2-ketoacid. Ultimately, through contact with additional enzymes, such C6-C10 aldehydes may be converted to, for example, C6-C10 alcohols, C6-C10 carboxylic acids, C6-C10 alkanes, and other derivatives. Use of the novel genetically modified phenylpyruvate decarboxylases may represent a lower cost alternative to non-biobased approaches.

Abstract: Novel carbon molecular sieve (CMS) compositions comprising carbonized vinylidene chloride copolymer having micropores with an average micropore size ranging from 3.0 to 5.0. These materials offer capability in separations of gas mixtures including, for example, propane/propylene; nitrogen/methane; and ethane/ethylene. Such may be prepared by a process wherein vinylidene chloride copolymer beads, melt extruded film or fiber are pretreated to form a precursor that is finally carbonized at high temperature. Preselection or knowledge of precursor crystallinity and attained maximum pyrolysis temperature enables preselection or knowledge of a average micropore size, according to the equation ?=6.09+(0.0275×C)?(0.00233×T), wherein ? is the average micropore size in Angstroms, C is the crystallinity percentage and T is the attained maximum pyrolysis temperature in degrees Celsius, provided that crystallinity percentage ranges from 25 to 75 and temperature in degrees Celsius ranges from 800 to 1700.
