Abstract: The disclosure relates to a method for treating an active beehive infested with pests. The method includes delivery of an oligomeric polyester including polyol backbone units, diacid backbone units, and formic acid capping units. Hydrolysis of the oligomeric polyester in the beehive upon exposure to environmental water to release formic acid and diacid over time, which kill the pests. The released formic acid is a relatively volatile liquid, allowing it to reach pests essentially anywhere in the hive. The diacid (such as oxalic acid) is generally a non-volatile solid, but it can be transported throughout the hive via normal bee movement within the hive, thus reaching pests beyond the initial point of application.

Abstract: The present disclosure provides methods to produce para-xylene, toluene, and other compounds from renewable sources (e.g., cellulose, hemicellulose, starch, sugar) and ethylene in the presence of a catalyst. For example, cellulose and/or hemicellulose may be converted into 2,5-dimethylfuran (DMF), which may be converted into para-xylene by cycloaddition of ethylene to DMF. Para-xylene can then be oxidized to form terephthalic acid.

Abstract: This invention relates to a novel process for preparing vinylsiloxane-BCBs (vinylsiloxane-benzocyclobutenes) comprising reacting a hydrolyzable hydrosilating reagent with an acetylene-BCB in the presence of a catalyst, then hydrolyzing the hydrolyzable vinylsilane-BCB to form a vinylsiloxane-BCB.

Abstract: A crude vinylically unsaturated product formed from a palladium-complex-catalyzed reaction of a reactant halide selected from the group consisting of aryl, allyl, vinyl, and benzyl halides, and a reactant olefin having a vinylic hydrogen, wherein the reaction is carried out in the presence of a hydrogen halide acceptor, is purified by first contacting the crude product with a base that is stronger than the hydrogen halide acceptor, then heating the stronger base-contacted product. The purified product shows a marked reduction in concentration bromine and palladium impurities. The product can then be further purified by such methods as chromatography, crystallization, or distillation to achieve a product that is more suitable for applications where very low levels of inorganic impurities are required.

Abstract: This invention relates to a novel process for preparing vinylsilane-BCBs (vinylsilane-benzocyclobutenes) comprising reacting a hydrosilating reagent with an acetylene-BCB in the presence of a catalyst.The invention also relates to a novel mixture of isomers of DVS-bisBCB (1,3-divinyl-1,1,3,3-tetramethyldisiloxane bisbenzocyclobutene) as well as novel partially or fully cured polymers derived from the vinylsilane BCBs.

Abstract: Hydroxy-functionalized polyethers having imide groups in their backbones are prepared by contacting an imide-containing bisphenol with the diglycidyl ether of the same or another bisphenol under conditions sufficient to cause the nucleophilic phenolic hydroxyl moieties to react with epoxy groups. These poly(hydroxy ether imides) possess a combination of high barrier to oxygen transmission (i.e., oxygen transmission rates of less than 10.0 cm.sup.3 -mil/100 in.sup.2 -atm-day) and high heat resistance (i.e., T.sub.g above 120.degree. C.). These polymers are suitable for use in the manufacture of packaging materials with high barrier to oxygen.

Abstract: 2-amino-3-methyl-1-naphthalenecarbonitriles of the formula: ##STR1## wherein R is alkyl of from 1 to 6 carbon atoms, halogen, cyano, or hydrogen are prepared by pyrolizing a by-product of a SAN or ABS manufacturing process of the formula: ##STR2## wherein R is alkyl of from 1 to 6 carbon atoms, halogen, cyano, or hydrogen.In another respect, this invention is a process for identifying aldehydes comprising: (a) contacting 2-amino-3-methyl-1-naphthalene-carbonitrile with aldehydes to form an UV-absorbing imine, and (b) analyzing the imine using conventional analytical techniques to identify the presence of the imines.
