Description
技术领域
本发明涉及一种防腐剂的制备方法,具体涉及一种尼泊金甲酯钠的制备方法。
背景技术
尼泊金甲酯钠作为尼泊金酯的改性产品,拥有尼泊金酯的抑菌性能和安全性能,同时克服了尼泊金酯水溶性低的缺陷。许多国家和地区把尼泊金甲酯钠作为食品防腐剂,已广泛应用于肉制品、脂肪制品、乳制品、水产品、调味品、糖果、果蔬制品、啤酒、果酒及果蔬保鲜等领域。尼泊金甲酯钠作为一种新型的光谱、高效防腐剂,同苯甲酸钠和山梨酸钾相比,具有以下优势:抑菌效果好、适用的pH范围广、毒副作用小、使用成本低、方便。
发明内容
本发明的目的在于,提供一种尼泊金甲酯钠的制备方法,生产工艺简便易行,原料易得,降低了生产成本,生产过程无“三废”产生,绿色环保。
所述尼泊金甲酯钠的制备方法,包括以下步骤:
一、先将对羟基苯甲酸甲酯加入反应容器中,然后取1.05倍对羟基苯甲酸甲酯摩尔量的氢氧化钠,缓慢滴加到反应器中,室温下反应1h;
二、反应完毕,静置结晶,离心过滤,真空干燥,即得成品尼泊金甲酯钠。
本发明提供的尼泊金甲酯钠的制备方法,其有益效果在于,生产工艺简便易行,原料易得,降低了生产成本,生产过程无“三废”产生,绿色环保。
具体实施方式
下面结合一个实施例,对本发明提供的尼泊金甲酯钠的制备方法进行详细的说明。
实施例
一、先将1mol对羟基苯甲酸甲酯加入反应容器中,然后将1.05mol氢氧化钠缓慢滴加到反应器中,室温下反应1h;
