    • The novel derivatives correspond to the general formula II: ##STR1## in which: R.sub.1 R.sub.2 R.sub.3 and R.sub.4 represent identical or different groups which can each be a hydrogen or halogen atom or an alkyl group, alkoxy, or benzyloxy group and R is the residue of an R--CHO aldehyde selected from among linear or branched saturated aliphatic aldehydes including 1 to 4 carbon atoms or again represents the Z--CH.dbd.CH radical in which Z represents a hydrogen atom, a linear or branched saturated alkyl group, an aromatic nucleus or an aromatic heterocyclic nucleus or again R represents the radical HO CH.sub.2 (CH OH)n--in which n has the value of 3 or 4. The novel compounds have high solubility in water and antibacterial activity and potentiating power.
    • 新衍生物对应于通式II:其中:R 1 R 2 R 3和R 4表示可以各自为氢或卤素原子或烷基,烷氧基或苄氧基的相同或不同的基团,R 是选自包括1至4个碳原子的直链或支链饱和脂族醛中的R-CHO醛的残基,或再次代表Z-CH = CH基团,其中Z表示氢原子,直链或支链饱和烷基, 芳香核或芳族杂环核,或者再次R代表基团HO CH 2(CH OH)n - ,其中n的值为3或4.新化合物在水中具有高溶解度和抗菌活性和增效能力。
