CAS: 1758-25-4
分子式: C10H12O4
分子量: 196.20
熔点: 122-126℃
中文名称: 
2,5-二甲氧基苯基乙酸
2,5-二甲氧基苯乙酸
英文名称: 
2,5-dimethoxy-benzeneacetic aci
(2,5-dimethoxyphenyl)acetic acid
(2,5-Dimethoxyphenyl)
2,5-Dimethoxyphenylacetic Acid
性质描述: 白色针状结晶。熔点124.5℃。易溶于热水、乙醇、乙醚和氯仿,难溶于水。
生产方法: 由对二甲氧基苯经下述步骤制得。将二硫化碳、氯乙酰和二甲氧基苯混合,在搅拌下加至三氯化铝与二硫化碳的混合物中,反应温度保持在5℃左右。将反应混合物放入冰水中,用二硫化碳提取,提取液回收二硫化碳后减压蒸馏,得2,5-二甲氧基苯乙酮。将其与乙醇、氢氧化钠溶液回流45h,加盐酸酸化至pH=2,用水结晶即得成品。
用途: 用于有机合成。
