Abstract: Epoxy resin which results from dehydrogenating the reaction product of an excess of at least one epihalohydrin with at least one phosphoramide compound represented by formula (I), wherein each R is independently hydrogen or a hydrocarbyl or an inertly substituted hydrocarbyl group having from 1 to 20 carbon atoms, with the proviso that at least two of the R groups are hydrogen, and removing the excess epihalohydrin. Mixtures of the epoxy resins of this invention with curing agents are useful in the preparation of castings, laminates or coatings.

Abstract: The insulating edge tape is provided with a longitudinal segment (4) flat on both sides and a longitudinal segment (5) connected thereto and profiled on one side. The height (6) of the longitudinal segment (4) flat on both sides correspond to the gap (7) between a corresponding hollow and the lower flat side (1) of the tape. The tape may be fabricated from a one piece plastic blank, thereby reducing the manufacturing costs. A notch (9) between the longitudinal segment (4) flat on both sides and the longitudinal segment (5) with an ondulated profiling on one side enables an easy bending of the tape for the mounting thereof. Since the ondulated profiling (8) is horizontal when the insulating edge tape is mounted, it is impossible to foreign bodies to fall into the hollows and to affect the flexibility of the insulating edge tape.

Abstract translation: 绝缘边缘带具有在两侧上平坦的纵向段（4）和与其连接并在一侧成形的纵向段（5）。 扁平纵向段（4）在两侧上的高度（6）对应于条的相应中空部分和平坦底侧（1）之间的间隙（7）。 胶带可以由单件塑料坯料制成，因此制造成本降低。 在两侧平坦的纵向节段（4）和一侧成型为波纹状的纵向节段（5）之间形成的凹口（9）允许用于安装的带的容易弯曲。 由于当安装边缘绝缘条时波纹轮廓（8）是水平的，所以异物不可能落入凹陷中并且不利地影响边缘绝缘条的柔性。

Abstract: Unitary, cast structural element (10) for a filter press electrolysis cell which incorporates into a single unit the central barrier (14) between the peripheral boundaries for the adjacent anolyte compartment (22) and the adjacent catholyte compartment (24) of two electrolysis cells located on opposite sides of the central barrier (14). Also incorporated into the single cast structural element (10) are anode bosses (18) and cathode bosses (20) extending outwardly from opposite sides of the central barrier. These bosses (18, 20) not only serve as mechanical support for their respective flat plate anode (36) and cathode (46), but also serve as stand-off means and electrical current collectors and disperses from the cathode (46) of one electrolysis cell to the anode (36) of the next cell. Simplicity of design coupled with incorporation of many functional elements into one part eliminates many warpage problems, inherent high voltage problems and membrane (27) "hot spot" problems.

Abstract: The present invention is a process for removing water from an alkanesulfonic acid such as methanesulfonic acid or ethanesulfonic acid by mixing an azeotropic excess of a phenolic compound with water and the alkanesulfonic acid, then boiling off substantially all of the water, and leaving as a remnant substantially all the alkanesulfonic acid and some of the phenol. This process is particularly useful for recycling an alkanesulfonic acid for a reaction which requires the phenolic compound as one of the reagents. One such reaction is the alkanesulfonic acid catalyzed condensation reaction of a phenolic compound with an alpha -haloketone to form a chlorinated intermediate of a dihydroxy- alpha -alkylstilbene such as 4,4'-dihydroxy- alpha -alkylstilbene (DHAMS).
