A method of preventing the growth of fungi and bacteria including Gram-negative bacteria in water-containing compositions characterised by the addition to the composition, as an agent for the control of Gram-negative bacteria, of one or more compounds of the general formula:
where X represents CHO or a mannic base, represented by
where R, and R2 each represent an alkyl group (preferably containing 1 to 4 carbon atoms), or, together with an oxygen atom form the residue of an N-morpholinyl ring,
A represents fluorine, bromine, chlorine, iodine, an alkyl group containing from 1 to 4 carbon atoms, an alkoxy group containing from 1 to 4 carbon atoms, a hydroxyl group, a nitro group, a primary amino group or hydrogen;
B represents fluorine, bromine, chlorine, iodine, an alkyl group containing 1 to 4 carbon atoms, an alkoxy group containing 1 to 4 carbon atoms, a hydroxy group, a nitro group, a primary amino group or hydrogen provided that where X is a mannic base only one of A and B may represent hydrogen.
一种防止含水组合物中真菌和细菌(包括革兰氏阴性菌)生长的方法,其特征在于作为控制革兰氏阴性菌的制剂,在组合物中加入一种或多种通式化合物:
式中 X 代表 CHO 或曼尼农碱,由以下式表示
其中 R 和 R2 分别代表烷基(最好含有 1 至 4 个碳原子),或与氧原子一起构成 N-吗啉基环的残基、
A 代表氟、溴、氯、碘、含 1 至 4 个碳原子的烷基、含 1 至 4 个碳原子的烷氧基、羟基、硝基、伯氨基或氢;
B 代表氟、溴、氯、碘、含 1 至 4 个碳原子的烷基、含 1 至 4 个碳原子的烷氧基、羟基、硝基、伯氨基或氢,但在 X 为曼尼基的情况下,A 和 B 中只能有一个代表氢。
