Abstract: PROBLEM TO BE SOLVED: To provide a process for preparing a monodisperse anion exchanger, preferably a monodisperse, large-pores anion exchanger which has a high mechanical and permeation stability of particles, has an increased absorptive power for anions, requires a reduced amount of resources for preparing the anion-exchanger itself and has a highly pure function basic group and can be prepared in a high yield. SOLUTION: In a process for preparing a monodisperse anion exchanger, (a) monomer droplets prepared from at least one monovinyl aromatic compound and at least one polyvinyl aromatic compound are allowed to undergo a reaction to generate a crosslinked monodisperse bead polymer, (b) this monodisperse bead polymer is subjected to amidomethylation using a phthalimide derivative, (c) this amidomethylated bead polymer is allowed to undergo a reaction to generate an aminomethylated bead polymer, and (d) this aminomethylated bead polymer is alkylated.

Abstract: PROBLEM TO BE SOLVED: To provide a method of producing a monodisperse crosslinked bead polymer useful as an ion exchange resin. SOLUTION: This method of producing the monodisperse crosslinked bead polymer is carried out through seed/feed-polymerization, wherein the seed comprising monomer droplets incompletely polymerized, monodispersed, and microencapsulated is used to obtain the objective polymer low in a soluble polymer content.

Abstract: PROBLEM TO BE SOLVED: To provide a complexing agent without having any toxico-ecological drawback. SOLUTION: This iminodisuccinic acid ammonium metal salt is expressed by formula 8: IDA(NH 4 ) x (Na) y (K) z (Me) m -(NH 3 ) n . The method for producing iminodisuccinic acid ammonium metal salt expressed by formula 8 comprises a first process of mixing maleic anhydride (MA) with an alkali metal hydroxide and water by (2:0-3:5-30) molar ratio, and then blending ammonia by MA:ammonia=(2:1.5-8) molar ratio to obtain iminodisuccinic acid ammonium salt and a second process of performing a reaction by mixing the obtained salt with a metal oxide, metal hydroxide and/or other metal salts or their mixtures.

Abstract: New chelated trace nutrients (I) for plants comprise the reaction products of at least one complex former (A) selected from sodium, potassium, sodium/ammonium or potassium/ammonium salts of N-(1,2-dicarboxyethyl)-D,L-aspartic acid and metal ions (B) derived from inorganic or organic zinc, manganese, iron (II) or copper (II) compounds. An Independent claim is included for the preparation of chelated plant trace nutrient fertilizers (I'), by reacting a complex former (A') having an imino group and multiple carboxylic acid groups with a compound (B') selected from the chlorides, nitrates, acetates and sulfates of iron, manganese, copper or zinc (or with a corresponding metal hydroxide, carbonate or oxide in presence of an (in)organic acid).

Abstract: Weakly basic anion exchangers of the poly(meth)acrylamide type, which have been prepared by aminolysis of poly(meth)acrylonitrile or poly(meth)acrylate with polyamines of a defined composition, have an improved uptake capacity for sulphate ions and are suitable for selective removal of sulphate ions from aqueous liquids, especially from sodium chloride brines and from waste waters.
