产品详情

详细信息(中文):
外观性状编辑
白色结晶,mp136~138℃。溶
于氯仿、醇、醚、苯等,微溶于水。在空气中稳定,遇光颜色变深,毒性小,防霉能力一般。主要用于聚氯乙烯等塑料、棉、毛、橡胶、黏合剂、纤维、皮革、涂料等防霉。可由水杨酸与苯胺在三氯化磷作用下反应制得,或由水杨酸甲酯与苯胺反应制得。在此基础上开发的3,4',5-三溴水杨酰苯胺,防霉能力大大提高。适用于塑料、橡胶、纤维,对聚氯乙烯薄膜的防霉特别有效。也是肥皂和化妆品的杀菌剂。
白色或略带红色的结晶。难溶于水,易溶于乙醇、乙醚中。
主要作用编辑
抗真菌作用较强,对小孢子菌和某些毛癣菌有效。常用其5%软膏治疗皮癣。与十一烯酸配合,可增强药效,减少刺激 [1] ,是肥皂和化妆品的杀菌剂。
制备过程编辑
将适量水杨酸苯酯投入50ml圆底烧瓶,由于加热至120℃,使熔融,不时摇动圆底烧瓶,并在此温度维持5min左右,然后按1g水杨酸苯酯加0.45ml苯胺的比例,加入苯胺,安装回流冷凝器,加热至160+5℃,反应2h,温度稍降后,趁热倾入30 ml85%乙醇中,置于冰水浴中搅拌,直至结晶析出,过滤,用85%乙醇洗两次,干燥,得粗品。
取粗品,投入附有回流冷凝器的圆底烧瓶中,加4倍量的(w/v)的95%乙醇,在60℃水浴中,使之溶解,加少量活性碳及EDTA脱色10min,趁热过滤,冷却、过滤。用少量乙醇洗两次(母液回收)。干燥得本品。

Appearance editor
White crystalline, mp136 ~ 138 ℃. soluble
In chloroform, alcohol, ether, benzene, etc., slightly soluble in water. Stability in the air, with light color is darker, low toxicity, mildew proof ability. Is mainly used in polyvinyl chloride (PVC) plastic, such as cotton, wool, rubber, adhesive, fiber, leather, coating and other mouldproof. Can be made of salicylic acid and aniline reaction under the effect of phosphorus trichloride, or by salicylic acid methyl ester was prepared with aniline reaction. On the basis of the development of 3, 4 ', 5 - three bromine water Yang acyl aniline, mildew-proof ability is greatly increased. Suitable for plastic, rubber, fiber, mouldproof particularly effective for polyvinyl chloride (PVC) film. Fungicide and soap and cosmetics.
White or reddish crystallization. Poorly soluble in water, soluble in ethanol, ethyl ether.
Main effect editor
Antifungal effect is stronger, the small spore bacteria and some wool tinea bacteria effectively. Commonly used 5% ointment in treating ringworm. Cooperate with 11 acid, can enhance effectiveness, reduce the stimulation [1], is a fungicide soap and cosmetics.
The preparation process of editing
Put a moderate amount of salicylic acid benzyl ester into 50 ml round bottom flask, because of the heated to 120 ℃, melting, shaking round bottom flask, from time to time and temperature on this lasts for 5 min, and then press 1 g salicylic acid benzyl ester and the ratio of 0.45 ml aniline, join the aniline, install the reflux condenser, heated to 160 + 5 ℃, 2 h reaction, temperature slightly reduced after strike into 30 ml85 % ethanol, put in ice water bath stirring, until crystallization precipitation, filtration, using 85% ethanol to wash twice, dry, coarse product.
Take crude products, in the round bottom flask the reflux condenser attached and add 4 times the amount of 95% (w/v) of ethanol, in 60 ℃ water bath, dissolved, add a small amount of activated carbon and EDTA decoloring 10 min,
