- 不溶于水,溶于碱性氢氧化物和碳酸盐溶液,微溶于热盐酸。
- 用途二:用于药物、染料和彩色胶片成色剂的合成。
- 方法一:由柠檬酸经酯化、氨解、闭环而得。酯化反应在硫酸存在下进行,经48h脱水后,回收溶剂和乙醇,残留物经水洗、碱洗、水洗至pH为6,得柠檬酸三乙酯粗品。加入氨水,通氨至饱和。放置以后,再通氨饱和,每天饱和一次,共三次,滤出结晶,将所得柠檬酸三甲酸胺于硫酸存在下120℃左右保温3h,慢慢倒入蒸馏水中,得粗品,再用酸碱精制而得柠嗪酸。采用柠檬酸三甲酯的制备方法大致与上述过程相同。在柠檬酸三甲酯中加入氨水,于室温放置约48h,浓缩后,加75%硫酸,放置12h,于130℃加热10min,用水稀释,过滤沉淀物即得粗品。将粗品溶于氨水,加盐酸即得沉淀,过滤,水洗,干燥。收率为69%。
