A method is provided for the production of antimicrobially effective phenol derivatives according to general Formula I in which R.sub.1 is bromine or chlorine, R.sub.2 is methyl or ethyl, R.sub.3 is hydrogen or sodium, potassium, ammonium or by alkyl with up to 10 C-atoms substituted ammonium, magnesium, calcium, barium, aluminum, tin, bismuth, copper, zinc, R.sub.4 and R.sub.5 are independently hydrogen, alkyl or alkoxy with up to 5 C-atoms, bromine or chlorine. The compounds are obtained by benzylation of 6-halogen- or 4-halogen-2-alkylphenol, halogenation of 2-alkyl-4-benzylphenol or -6-benzylphenol, or by alkylation of 6-halogen-4-benzylphenol or of 4-halogen-6-benzylphenol and if necessary through reaction of the product with hydroxide, alcoholate, carbonate or hydrogen carbonate of the above-mentioned metals. Water or lipid soluble effective substances are obtained which display a broad antimicrobial activity spectrum.
提供了一种制备具有抗微生物作用的苯酚衍生物的方法,其通式为I式,其中R.sub.1为溴或氯,R.sub.2为甲基或乙基,R.sub.3为氢或钠、钾、铵或被取代的具有高达10个碳原子的烷基的铵、镁、钙、钡、铝、锡、铋、铜、锌,R.sub.4和R.sub.5独立地为氢、烷基或具有高达5个碳原子的烷氧基、溴或氯。该化合物是通过苯甲基化6-卤代或4-卤代-2-烷基苯酚,2-烷基-4-苯甲基苯酚或-6-苯甲基苯酚的卤代反应,或通过6-卤代-4-苯甲基苯酚或4-卤代-6-苯甲基苯酚的烷基化反应获得的,必要时通过与上述金属的氢氧化物、醇盐、碳酸盐或氢氧碳酸盐的反应来反应。可以获得水溶性或脂溶性的有效物质,具有广泛的抗微生物活性谱。
