Permutites

Sulfonated styrene—divinylbensene cross-linked polymers have been appHed in many of the previously mentioned reactions and also in the acylation of thiophene with acetic anhydride and acetyl chloride (209). Resins of this type (Dowex 50, Amherljte IR-112, and Permutit Q) are particularly effective catalysts in the alkylation of phenols with olefins (such as propylene, isobutylene, diisobutylene), alkyl haUdes, and alcohols (210) (see Ion exchange). Superacids.

Ionics Incorporated (Watertown, Massachusetts), the leading ED suppHer, has sold more than 2000 ED and EDR plants having a combined capacity of probably more than 600,000 mr / d. These were originally furnished with probably more than 1.2 x 10 of membrane. More than 2000 other ED and EDR plants have been built and installed in China. These plants have a combined capacity of more than 600,000 mr / d and were originally furnished with probably more than 1.2 x 10 of membrane. Also it is estimated that more than 1000 ED and EDR plants have been built and installed in the CIS. These plants have a combined capacity of probably more than 300,000 m /d, probably originally furnished with more than 600,000 m of membrane. Roughly 100 plants have been installed by other companies such as Corning Erance (formerly S.R.T.I.) and Portals Water Treatment Ltd. (formerly Permutit-Boby).

Words ending in -it in German, as, for instance, the names of a great many minerals, should as a rule be translated with the ending -ite as, Kainit, kainite (not kainit). If it seems best to retain the original speUing of a trade name it should be placed in quotation marks or its initial letter should be capitalized as, Permutit, permutite or permutit or Permutit.

Ammonia-free water may be prepared in a conductivity-water still, or by means of a column charged with a mixed cation and anion exchange resin (e.g. Permutit Bio-Deminrolit or Amberiite MB-1), or as follows. Redistil 500 mL of distilled water in a Pyrex apparatus from a solution containing 1 g potassium permanganate and lg anhydrous sodium carbonate reject the first 100 mL portion of the distillate and then collect about 300 mL. 

Other IX designs employed to reduce resin volume include, for example, the Permutit (now Yivendi/U.S. Filter Corp.) Scion short cycle deionizer design and the Scion-Hipol (which has a cation polishing unit on the two-stage deionizer).
