    摘要： Disclosed is an improved method for the preparation of highly pure haloformimine compounds in high yields by reacting a formimine compound in a solvent with a halogenating agent while maintaining the pH of the halogenation reaction in the range of 2 to 5. The pH of the reaction may be maintained by a variety of means, such as by the addition of a base.

    摘要： The invention relates to the inhibition of (poly)phosphate scale in aqueous systems involving the use of at least one copolymer comprising the following monomers in polymerized form:-
    (I) 50-08% by weight of one or more weak acids; (II) 2-50% by weight of one or more strong acids; (III) 0-30% by weight of one or more monoethylenically unsaturated C 4 -C 8 dicarboxylic acids; and (IV) 0-30% by weight of one or more monoethylenically unsaturated monomers polymerizable with (I), (II) and (III); wherein the total of monomers (I), (II), (III) and (IV) equals 100% by weight of copolymer. The invention is particularly suited to the inhibition of (poly)phosphate scale which occurs as a result of using low phosphate (STPP) containing detergent formulations.

    摘要： A process for preparing anhydride polymers in aromatic hydrocarbon solvents using a dialkyl peroxide/amine compound initiator system is disclosed. The amine compound allows more efficient use of free-radical initiators while achieving high monomer conversion polymerizations compared to conventional initiator systems, particularly in the preparation of maleic anhydride polymers.
