Description
技术领域
本发明属于农用除草剂领域,特别是涉及草甘膦除草离子液体类化合物及其制备和应用。
背景技术:
草甘膦(glyphosate),又名镇草宁、农达(Roundup)等,其化学名称为:N-(膦酰基甲基)甘氨酸,是1971年由美国孟山都公司开发的一种有机磷除草剂。草甘膦是目前世界上最经济的内吸传导非选择性除草剂,其主要通过茎叶吸收,传导至地下部分,抑制植物体内烯醇丙酮基莽草素膦酸合成酶,从而抑制植物体内莽草素向苯丙氨酸、酪氨酸及色氨酸转化,是蛋白质合成受到干扰,导致杂草死亡。
离子液体是由阴、阳离子构成的熔点低于100℃的盐(许多在室温呈液态)。离子液体具有几乎无蒸气压、高的热稳定性和化学稳定性、优良的溶解性能、优异的电化学特性及易回收、可设计等优点,其绝大多数的应用研究都集中在溶剂、催化和新材料方面。近几年来离子液体的物理化学属性、生物学性质备受关注。由于离子液体的活性可以通过离子液体的可设计性进行调节,而且许多常见离子液体的结构或组分和活性药物成分的前驱体相似,人们开始认识到它可能具有潜在的生物活性。
最近许多学者纷纷致力于离子液体应用于药物及农用化学品的研究。国外Pernak首次(ACS Sustainable Chem.Eng.,2014,2,2845-2851)报道了草甘膦除草离子液体,对此类离子液体化合物的除草活性进行了初步探索,新型草甘膦除草离子液体由于阳离子的引入,改变草甘膦理化性质的同时,明显提高了草甘膦除草的活性。草甘膦除草剂作为全球第一大农药,对其开展增效改性研究,对控制农药使用量,减少对环境危害显的尤为重要。
