產品詳情

詳細信息(中文):
外觀性狀編輯
白色結晶,mp136~138℃。溶
于氯仿、醇、醚、苯等,微溶于水。在空氣中穩定,遇光顏色變深,毒性小,防霉能力一般。主要用于聚氯乙烯等塑料、棉、毛、橡膠、黏合劑、纖維、皮革、涂料等防霉。可由水楊酸與苯胺在三氯化磷作用下反應制得,或由水楊酸甲酯與苯胺反應制得。在此基礎上開發的3,4',5-三溴水楊酰苯胺,防霉能力大大提高。適用于塑料、橡膠、纖維,對聚氯乙烯薄膜的防霉特別有效。也是肥皂和化妝品的殺菌劑。
白色或略帶紅色的結晶。難溶于水,易溶于乙醇、乙醚中。
主要作用編輯
抗真菌作用較強,對小孢子菌和某些毛癬菌有效。常用其5%軟膏治療皮癬。與十一烯酸配合,可增強藥效,減少刺激 [1] ,是肥皂和化妝品的殺菌劑。
制備過程編輯
將適量水楊酸苯酯投入50ml圓底燒瓶,由于加熱至120℃,使熔融,不時搖動圓底燒瓶,并在此溫度維持5min左右,然后按1g水楊酸苯酯加0.45ml苯胺的比例,加入苯胺,安裝回流冷凝器,加熱至160+5℃,反應2h,溫度稍降后,趁熱傾入30 ml85%乙醇中,置于冰水浴中攪拌,直至結晶析出,過濾,用85%乙醇洗兩次,干燥,得粗品。
取粗品,投入附有回流冷凝器的圓底燒瓶中,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脫色10min,趁熱過濾,冷卻、過濾。用少量乙醇洗兩次(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,
