  • 参考质量标准:GB
  • 用途八:苯甲酸和它的钠盐是食品的重要防腐剂。在酸性条件下，对酵母和霉菌的抑制作用，pH值为3时抗菌力量强，而pH为6时对很多霉菌效果很差，故其抑菌最适pH值为2.5-4.0。苯甲酸主要用于生产苯甲酸钠食品防腐剂，染料
  • 具有苯或甲醛的气味，易燃。质轻。无气味或微有类似安息香或苯甲醛的气味。在100℃时迅速升华，能随水蒸气同时挥发。易溶于醇、氯仿、醚和丙酮，能溶于苯、二硫化碳、松节油及油类，微溶于水和石油醚
  • 方法四:最初由安息香胶干
  • 储运特性:通风低温干燥; 与氧化剂分开存放
  • 外观性质:鳞片状或针状结晶, 具有苯或甲醛的臭味。

  • 用途六:苯甲酸是重要的酸型食品防腐剂。在酸性条件下，对霉菌、酵母和细菌均有抑制作用，但对产酸菌作用较弱。抑菌的最适pH值为2.5～4.0，一般以低于pH值4.5～5.0为宜。在食品工业用塑料桶装浓缩果蔬汁，最大使用量不得超过2.0g/kg；在果酱(不包括罐头)、果汁(味)型饮料、酱油、食醋中最大使用量1.0g/kg；在软糖、葡萄酒、果酒中最大使用量0.8g/kg；在低盐酱菜、酱类、蜜饯，最大使用量0.5g/kg；在碳酸饮料中最大使用量0.2g/kg。由于苯甲酸微溶于水，使用时可用少量乙醇使其溶解。

  • 制备:工业制法 目前工业上苯甲酸主要是通过甲苯的液相空气氧化制取的。过程是以环烷酸钴为催化剂，在反应温度为140－160℃和操作压力0.2－0.3MPa下反应生成苯甲酸。反应后蒸去甲苯，并减压蒸馏、重结晶，即得产品。该工艺利用廉价原料，收率高，因此是工业上主要使用的方法。 实验室制法 主反应： 1.甲苯+高锰酸钾+水——苯甲酸钾+氢氧化钾+二氧化锰+水（前面的水是提供反应环境） 2.苯甲酸钾+浓盐酸——苯甲酸 药品与用量： 甲苯1.5g(1.7ml,0.016mol)、高锰酸钾5g(0.032mol)、十六烷基三甲基溴化铵0.1g 实验操作： 用100ml的圆底烧瓶。安装回流装置。向反应瓶中分别加入5g高锰酸钾，0.1g十六烷基三甲基溴化铵，1.7ml甲苯及50ml水，搅拌加热沸腾（剧烈搅拌，猛烈沸腾），保持反应物溶液平稳沸腾。 当大量棕色沉淀生成，高锰酸钾的紫色变浅或消失，甲苯层消失时，反应基本结束。过滤出二氧化锰沉淀，滤液用浓盐酸酸化，析出苯甲酸的沉淀，抽滤得粗产品。 粗产品用水重结晶。在沸水浴上干燥，称量，测其熔点。
