本文结合国外情况对尿囊素、香兰素、乙基香兰素、对甲氧基苯甲醛、儿茶醛、胡椒醛、扁桃酸、二苯基乙酸、对羟基苯乙酸、苯并二呋喃酮系列化合物、苯甘氨酸、对羟基苯甘氨酸、泛酸钙、2-羟基喹(?)啉、2-羟基膦酰基乙酸等乙醛酸下游产品的国内市场与科研情况做了较详细地论述。预计,我国目前GA的总需求量约为9000t/a,消费构成大致为,苯甘氨酸类占42.3%、尿囊素占31.6%、芳香醛占20%、其它占6.1%,进口量约3000~4000t/a。
This article combines the situation abroad with allantoin, vanillin, ethyl vanillin, p-methoxybenzaldehyde, catechol, piperonal, mandelic acid, diphenylacetic acid, p-hydroxyphenylacetic acid, benzodifuran The domestic market and research status of glyoxylic acid downstream products such as ketone series compounds, phenylglycine, p-hydroxyphenylglycine, calcium pantothenate, 2-hydroxyquinoline, and 2-hydroxy phosphonoacetic acid were discussed in detail. It is estimated that the current total demand for GA in China is about 9,000t/a, and the consumption composition is roughly 42.3% for phenylglycine, 31.6% for allantoin, 20% for aromatic aldehydes, 6.1% for others, and 3,000 for imports. 4000t/a.
