  Use of acylphosphonates for the synthesis of α-chlorinated carboxylic and α,α′-dichloro dicarboxylic acids and their derivatives

  摘要：

  alpha -Chloro acylphosphonates and alpha,alpha'-dichloro bisacylphosphonates were prepared in situ by chlorination of acylphosphonates and bisacylphosphonates, respectively, using sulfuryl chloride. Subsequently, they were cleaved to the corresponding alpha -chlorinated or alpha,alpha'-dichlorinated (di)carboxylic acids with a hydrogen peroxide-sodium bicarbonate system. Performing the cleavage with an alcohol or an amine yielded the corresponding alpha -chlorinated esters and alpha -chlorinated amides, respectively. (C) 2001 Elsevier Science Ltd.

  In the step of extracting and removing a porogen from a thermosetting resin sheet 1 containing the porogen, the porogen is extracted and removed by bringing the thermosetting resin sheet 1 into contact with a first liquid that has a relatively low temperature, and subsequently bringing the thermosetting resin sheet 1 into contact with a second liquid that has a relatively high temperature. Preferably, the temperatures of the first liquid and the second liquid are lower than or equal to the glass-transition temperature of the thermosetting resin sheet 1.

  在从含有多孔剂的热固性树脂片 1 中提取和去除多孔剂的步骤中，通过使热固性树脂片 1 与温度相对较低的第一种液体接触，然后使热固性树脂片 1 与温度相对较高的第二种液体接触，来提取和去除多孔剂。第一种液体和第二种液体的温度最好低于或等于热固性树脂板 1 的玻璃化转变温度。

  The present invention provides a method for producing a porous membrane. The method allows: avoidance of use of a solvent that places a large load on the environment; relatively easy control of parameters such as the porosity and the pore diameter; and high chemical stability of a resultant porous membrane. The method for producing a porous membrane of the present invention includes the steps of: preparing an epoxy resin composition containing an epoxy resin, a curing agent represented by H2N-(CH2)n-NH2 where n is an integer from 4 to 8, and a porogen; forming a cured product of the epoxy resin composition into a sheet shape or curing a sheet-shaped formed body of the epoxy resin composition, so as to obtain an epoxy resin sheet; and removing the porogen from the epoxy resin sheet by means of a halogen-free solvent.

  本发明提供了一种生产多孔膜的方法。该方法可以：避免使用对环境造成较大负荷的溶剂；相对容易地控制孔隙率和孔径等参数；所制得的多孔膜具有较高的化学稳定性。本发明生产多孔膜的方法包括以下步骤：制备环氧树脂组合物，其中包含环氧树脂、以 H2N-(CH2)n-NH2 表示的固化剂（其中 n 为 4 至 8 的整数）和致孔剂；将环氧树脂组合物的固化产物制成片状或固化环氧树脂组合物的片状成型体，从而获得环氧树脂片；以及通过无卤溶剂去除环氧树脂片上的致孔剂。

  Provided is a method for producing a separator for nonaqueous electrolyte electricity storage devices that includes a porous epoxy resin membrane, the method including: a step (i) of preparing an epoxy resin composition containing an epoxy resin, a curing agent, and a porogen; a step (ii) of cutting a cured product of the epoxy resin composition into a sheet shape or curing a sheet-shaped formed body of the epoxy resin composition so as to obtain an epoxy resin sheet; a step (iii) of removing the porogen from the epoxy resin sheet using a halogen-free solvent so as to form a porous epoxy resin membrane; a step (iv) of irradiating the porous epoxy resin membrane with infrared ray so as to measure infrared absorption characteristics of the porous epoxy resin membrane; and a step (v) of calculating a membrane thickness and/or an average pore diameter of the porous epoxy resin membrane based on the infrared absorption characteristics. This production method can avoid the use of a solvent that places a large load on the environment, and is adapted for control of parameters such as the average pore diameter and the membrane thickness.

  A spiral membrane element is provided which has a restricted outer diameter but is heightened in effective membrane area, and further which can be decreased in operation energy therefor. The spiral membrane element is an element including plural membrane leaves (L) in each of which a permeation-side flow-channel member (3) is interposed between opposed separation membranes (1); a supply-side flow-channel member (2) interposed between any two of the membrane leaves (L); a perforated central pipe(5) on which the membrane leaves (L) and the supply-side flow-channel member (2) are wound; and sealing parts that prevent a supply-side flow-channel from being mixed with a permeation-side flow-channel. The sealing parts include both-end sealing parts (11) in which an adhesive is used to seal two-side end parts of each of the membrane leaves (L) on both sides of the leaf in an axial direction A1 of the leaf. The thickness (T1) of the both-end sealing parts (11) is 390 to 540 µm.

  本发明提供了一种螺旋膜元件，其外径有限，但有效膜面积增大，并可进一步降低操作能量。螺旋膜元件包括多个膜叶 (L)，每个膜叶中有一个渗透侧流道部件 (3)，穿插在相对的分离膜 (1) 之间；一个供给侧流道部件 (2)，穿插在任意两个膜叶 (L) 之间；一个带孔的中心管 (5)，膜叶 (L) 和供给侧流道部件 (2) 缠绕在该中心管上；以及防止供给侧流道与渗透侧流道混合的密封部件。密封部件包括两端密封部件 (11)，其中使用粘合剂密封每个膜片 (L) 在膜片轴向方向 A1 的两侧端部。两端密封部件（11）的厚度（T1）为 390 至 540 微米。
