  The present invention provides a nonaqueous electrolytic solution capable of improving electrochemical characteristics in the case of using an energy storage device at a high temperature and further capable of inhibiting the gas generation as well as a capacity retention rate after a high-temperature cycle, and also to provide an energy storage device using the same. Disclosed are a nonaqueous electrolytic solution having an electrolyte salt dissolved in a nonaqueous solvent, the nonaqueous electrolytic solution containing a phenyl ester compound represented by the following general formula (I), and an energy storage device. (In the formula, R f represents a fluoroalkyl group having 1 to 6 carbon atoms; X represents a halogen atom; each of p and q is an integer of 1 to 4; and (p+q) is 5 or less. A has a structure represented by —S(═O) 2 —, —C(═O)—, —C(═O)—O—, —C(═O)-L 1 -C(═O)—, —C(═O)-L 2 -P(═O)(OR)—O—, or —P(═O)(OR)—O—. Y represents a fluorine atom, a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, or an aryl group; L 1 represents an alkylene group, an alkenylene group, an alkynylene group, or a direct bond; L 2 represents an alkylene group; and R represents an alkyl group. However, only when A is —S(═O) 2 —, Y may be a fluorine atom; and only when A is —C(═O)—, Y may be a hydrogen atom. At least one hydrogen atom in each group of the aforementioned alkyl group, alkenyl group, alkynyl group, aryl group, alkylene group, alkenylene group, and alkynylene group may be substituted with a halogen atom.)

• Selective Hydrolysis of Aliphatic Dinitriles to Monocarboxylic Acids by a Nitrilase from Arabidopsis thaliana
  作者：Franz Effenberger、Steffen Oßwald

  DOI：10.1055/s-2001-17523

  日期：——

  The hydrolysis of a variety of dinitriles including α,ω-dicyanoalkanes 1, β-substituted glutaronitriles 5, and γ-cyanopimelonitrile 7 with a recombinant plant nitrilase from Arabidopsis thaliana, expressed in E. coli, is described. Conversion rate and selectivity of the hydrolysis of dinitriles 1a-f to ω-cyanocarboxylic acids 2a-f depend on the chain length. The enzyme activity markedly increases from malononitrile (1a) to octanedinitrile (1f). The selectivity, however, does not correlate with the rates. Up to a chain length of 6 C-atoms, the cyanocarboxylic acid is the only product, even at complete conversion of the starting material. Pimelonitrile (1e) is hydrolyzed to the cyanocarboxylic acid 2e without formation of diacid (<1%) up to 73% conversion. Glutaronitriles 5a-c were also hydrolyzed to the corresponding cyanobutanoic acids 6a-c with perfect selectivity. The nitrilase hydrolyzes exclusively the primary cyano group of 7 to give 3,5-dicyanoheptanoic acid (8a), whereby the selectivity is slightly reduced compared to the unsubstituted pimelonitrile (1e). If the hydrolysis is terminated at conversions ≤90%, pure 8a can be isolated in 72% yield (92% referred to conversion). After esterification of 8a to the methyl ester 8b, only the 5-cyano group but not the ester function was hydrolyzed enzymatically to give cyanoheptanedioic acid monoester (10).

  描述了使用来自阿拉伯芥（Arabidopsis thaliana）的重组植物腈水解酶在大肠杆菌中表达，对多种二腈（dinitriles）进行水解的过程，这些二腈包括α,ω-二氰烷烃1、β-取代的戊二腈5和γ-氰基庚腈7。二腈1a-f转化为ω-氰基羧酸2a-f的水解转化率和选择性依赖于链长。从丙二腈（1a）到辛烯二腈（1f），酶活性显著增加。然而，选择性与转化速率并不相关。对于6个碳原子以下的链长，氰基羧酸是唯一的产品，即使起始材料完全转化。庚腈（1e）在转化率达到73%时，仅被水解为氰基羧酸2e，而未形成二酸（<1%）。戊二腈5a-c也被水解为相应的氰基丁酸6a-c，具有完美的选择性。腈水解酶专门水解7的原料氰基，生成3,5-二氰基庚酸（8a），相比于未取代的庚腈（1e），选择性略有降低。如果在转化率≤90%时终止水解，可以以72%的产率（转化率92%）单独分离出纯8a。在将8a酯化为甲酯8b后，只有5-氰基基团而不是酯功能被酶催化水解，生成氰基庚二酸单酯（10）。
