  One object of the invention is to provide a method for preparing a 9,9-dialkoxy-7-nonynoate ester and (7E)-7,9-decadienoate ester, which are valuable as intermediates. The method for preparing a (7E)-7,9-decadienoate ester (5) comprises at least steps of: hydrolyzing a 9,9-dialkoxy-7-nonenoate ester (2), R 3 O(R 2 O)CHCH═CH(CH 2 ) 5 CO 2 R 1 , to form a (7E)-9-oxo-7-nonenoate ester (3); and subjecting the (7E)-9-oxo-7-nonenoate ester (3) to a Wittig reaction with a triarylphosphonium methylide (4), Ar 3 P═CH 2 , to form the (7E)-7,9-decadienoate ester (5). The 9,9-dialkoxy-7-nonenoate ester may be prepared by, for example, reducing a 9,9-dialkoxy-7-nonynoate ester (1).

  该发明的一个目的是提供一种制备9,9-二烷氧基-7-壬烯酸酯和(7E)-7,9-癸二烯酸酯的方法，这些化合物作为中间体具有很高的价值。制备(7E)-7,9-癸二烯酸酯(5)的方法至少包括以下步骤：水解9,9-二烷氧基-7-壬烯酸酯(2)，R3O(R2O)CHCH═CH(CH2)5CO2R1，形成(7E)-9-氧代-7-壬烯酸酯(3)；将(7E)-9-氧代-7-壬烯酸酯(3)与三芳基膦甲烯基化合物(4)，Ar3P═CH2，进行威蒂格反应，形成(7E)-7,9-癸二烯酸酯(5)。可以通过还原9,9-二烷氧基-7-壬炔酸酯(1)来制备9,9-二烷氧基-7-壬烯酸酯。

  An electrostatic machine includes a drive electrode and a stator electrode. The drive electrode and the stator electrode are separated by a gap and form a capacitor. The drive electrode is configured to move with respect to the stator electrode. The electrostatic machine further includes a housing configured to enclose the drive electrode and the stator electrode. The stator electrode is fixed to the housing. The electrostatic machine also includes a dielectric fluid that fills a void defined by the housing, the drive electrode, and the stator electrode. The dielectric fluid includes an ester.
