    摘要: Aqueous antimicrobial compositions which comprise a halogenated amide antimicrobial, such as 2,2-dibromonitrilopropionamide, a water miscible organic solvent such as a straight chain polyalkylene glycol (e.g., polyethylene glycol 200) or an ether thereof (e.g., a mono- or di-lower alkyl and/or phenyl ether) and water and which have improved stability are obtained by ensuring that such compositions are substantially free of glycols having a molecular weight of less than about 70 and of salts of organic acids. The resulting improved compositions exhibit reduced rates of decomposition of the halogenated amide antimicrobial relative to the corresponding aqueous compositions containing salts of organic acids and/or glycols having a molecular weight of less than about 70.

    摘要: An alkyl .alpha.-cyanoacetate is reacted with ammonia in a glycol solvent medium to form cyanoacetamide. Advantageously and without requirement of separation of the formed cyanoacetamide in glycol solvent (even though the next step and entire procedure can optionally commence with pre-formed cyanoacetamide), 2,2-dibromo-3-nitrilopropionamide is formed in situ by treating the cyanoacetamide in glycol with an appropriate mixture of bromine and an alkali metal bromate at about 10.degree. C-40.degree. C. Excellent and stable antimicrobial compositions may then be prepared, as part of an overall integrated process by incorporating in the resultant 2,2-dibromo-3-nitrilopropionamide-containing reaction mass an appropriate quantity of paraformaldehyde or equivalent satisfactory stabilizer at a suitably adjusted pH level.
