Description
相关申请的交叉引用
本申请要求2020年1月29日提交的美国临时申请号62/967,170的优先权,其公开内容通过引用以其全文结合至本文。
技术领域
本公开涉及氨基酸的衍生物和它们的合成方法,其中氨基酸衍生物具有表面活性性质。
背景技术
表面活性剂(具有表面活性性质的分子)是一类重要的具有高度受欢迎的特性的分子。表面活性剂可以是不带电荷的、两性离子的、阳离子的或阴离子的。通常,这些化合物是具有水不溶性疏水性“尾”基团和水溶性亲水性“头”基团的两亲性分子。这些化合物可以吸附在界面处,例如两种液体之间的界面、液体和气体之间的界面或者液体和固体之间的界面。在水和油之间的界面的情况下,亲水性头基团延伸到水中,而疏水性尾部延伸到油中。当加入到水中时,亲水性头基团延伸到水中,而疏水性尾部延伸到空气中。表面活性剂的存在破坏了水分子之间的分子间相互作用,将其替换为水分子和表面活性剂之间的较弱的相互作用。这导致降低的表面张力并且还可以用于稳定界面。
在足够高的浓度下,表面活性剂可以形成聚集体以限制疏水性尾部暴露于极性溶剂。一种这样的聚集体是胶束,其中分子排列成球体,其中疏水性尾部在球体内部,而亲水性头部在外部以与极性溶剂相互作用。给定的化合物对表面张力的作用和其形成胶束所在的浓度可以用作表面活性剂的限定特性。
表面活性剂广泛用于从洗涤剂到毛发护理产品到化妆品范围的制剂的商业应用中。具有表面活性性质的化合物用作肥皂、洗涤剂、润滑剂、润湿剂、发泡剂和铺展剂等。因此,一直需要鉴定和合成这样的化合物。
然而,仅从其结构可能难以预测给定的化合物是否具有表面活性性质,更不用说其它重要的特性,例如界面吸附动力学、可实现的最小表面张力和/或润湿疏水和/或疏油表面的能力,这些也是化合物是否将成为有用的表面活性剂所必需的。例如,某些氨基酸及其衍生物作为表面活性剂的构造单元是理想的,但是选择使用哪些氨基酸远不是直观的。由于溶解度的差异,这样的化合物的合成增加了另一层困难,这归因于存在于相同分子中的不同元素和部分。仍然需要能够容易地以商业规模经由直接途径合成的高效表面活性剂。
发明内容
本公开提供了具有表面活性性质的氨基酸的衍生物。所述氨基酸可以是天然存在的或合成的氨基酸,或者它们可以经由分子(例如内酰胺,例如己内酰胺)的开环反应获得。所述氨基酸可以被官能化以形成具有表面活性性质的化合物。特征性地,这些化合物可以具有低的临界胶束浓度(CMC)和/或降低液体表面张力的能力。

本公开提供了氨基酸的衍生物。氨基酸可以是天然存在的或合成的,或者它们可以从内酰胺(例如己内酰胺)的开环反应获得。本公开的化合物已经显示具有表面活性性质,并且可以用作例如表面活性剂和润湿剂。特别地,本公开提供了以下示出的式I的化合物:
其中R1、R2和R3独立地选自氢和C1-C6烷基,即C1、C2、C3、C4、C5或C6;n为2-5的整数,即2、3、4或5;m为9-20的整数,即9、10、11、12、13、14、15、16、17、18、19或20;且X为可选自氯离子、溴离子、碘离子和氢氧根离子的阴离子。
或者,本公开还提供了以下示出的式II的化合物:
其中X为可选自氯离子、溴离子、碘离子和氢氧根离子的阴离子。
本公开提供的一个具体化合物为6-(十二烷氧基)-N,N-二甲基-6-氧代己烷-1-氯化铵,具有下式:
这些化合物可通过各种方法合成。一种这样的方法包括打开内酰胺以产生具有N-末端的氨基酸,和使氨基酸的N-末端与烷基化试剂反应以产生叔胺。然后所得的叔胺可在酸性条件下与醇反应以提供具有N-末端的氨基酸酯。然后氨基酸酯N-末端可与酸反应产生季铵盐。
氨基酸可以是天然存在的或合成的,或者例如可以衍生自内酰胺(例如丙内酰胺、丁内酰胺、戊内酰胺和己内酰胺)的开环反应。开环反应可以是酸或碱催化的反应,并且酸催化的反应的实例示于下面的方案1中。
方案1
氨基酸在N-末端和C-末端之间可以具有少至2个或多至5个(即2、3、4或5个)碳。烷基链可以是支链或直链。烷基链可以被氮、氧或硫中断。烷基链可以被选自羟基、氨基、酰氨基、磺酰基、磺酸酯、羧基和羧酸酯的一个或多个取代基进一步取代。N-末端氮可以被酰基化或被一个或多个烷基烷基化。例如,氨基酸可以是6-(二甲基氨基)己酸。
氨基酸的衍生物可以如以下方案2中所示的合成。如所示的,6-氨基己酸用在甲酸中的甲醛回流处理,以得到6-(二甲基氨基)己酸。然后用醇(例如十二烷醇)在甲苯中在对甲苯磺酸(PTSA)的存在下处理游离的羧酸,得到相应的酯,十二烷基6-(二甲基氨基)己酸酯。然后在碳酸钠的存在下用甲基碘使N-末端烷基化。
方案2
本公开的化合物表现出表面活性性质。这些性质可以通过各种方法测量和描述。可以描述表面活性剂的一种方法是通过分子的临界胶束浓度(CMC)。CMC可以定义为胶束形成时的表面活性剂的浓度,并且在该浓度以上所有另外的表面活性剂都被并入胶束中。
随着表面活性剂浓度增加,表面张力降低。一旦表面被表面活性剂分子完全覆盖,胶束开始形成。这个点代表CMC以及最小表面张力。进一步加入表面活性剂将不会进一步影响表面张力。因此,CMC可以通过观察表面张力作为表面活性剂浓度的函数的变化来测量。测量这个值的一种这样的方法是Wilhelmy板法。Wilhelmy板通常是薄的铱-铂板,其通过线附着于天平并且垂直于空气-液体界面放置。天平用于测量通过润湿施加在板上的力。随后根据等式1使用该值来计算表面张力(γ):
等式1:γ=F/l cos θ
其中l等于润湿的周界(2w+2d,其中w和d分别是板的厚度和宽度),并且cos θ (液体和板之间的接触角)在不存在现有文献值的情况下假定为0。
用于评估表面活性剂性能的另一个参数是动态表面张力。动态表面张力是对于特定表面或界面年龄的表面张力值。在具有加入的表面活性剂的液体的情况下,这可能不同于平衡值。在表面刚产生之后,表面张力等于纯液体的表面张力。如上所述,表面活性剂降低表面张力;因此,表面张力下降,直到达到平衡值。达到平衡所需的时间取决于表面活性剂的扩散速率和吸附速率。
测量动态表面张力的一种方法依赖于泡压张力仪。该设备通过毛细管测量在液体中形成的气泡的最大内部压力。测量值对应于在某一表面年龄下的表面张力,即从泡形成开始到出现压力最大值的时间。表面张力对表面年龄的依赖性可以通过改变产生泡的速度来测量。
表面活性化合物也可以通过它们在固体基材上的润湿能力来评估,如通过接触角所测量的。当液体液滴与固体表面在第三种介质(例如空气)中接触时,在液体、气体和固体之间形成三相线。作用于三相线并在液体液滴处相切的表面张力单位矢量与表面之间的角度被描述为接触角。接触角(也称为润湿角)是液体对固体润湿性的量度。在完全润湿的情况下,液体完全铺展在固体上,并且接触角为0°。通常在1-100×CMC的浓度下测量给定的化合物的润湿性质,然而,它不是浓度依赖性的性质,因此润湿性质的测量可以在更高或更低的浓度下测量。
在一种方法中,可以使用光学接触角测角仪来测量接触角。该设备使用数码相机和软件通过分析表面上固着的液体液滴的轮廓形状来提取接触角。
本公开的表面活性化合物的潜在应用包括用作洗发剂、毛发调理剂、洗涤剂、无斑点漂洗溶液、地板和地毯清洁剂、用于涂鸦去除的清洁剂、用于作物保护的润湿剂、用于作物保护的助剂和用于气溶胶喷涂的润湿剂的制剂。
本领域技术人员将理解,化合物之间的小差异可以导致实质不同的表面活性剂性质,使得不同的化合物可以在不同的应用中与不同的基材一起使用。
提供以下非限制性实施方案以证明不同表面活性剂的不同性质。
化合物有效地作为表面活性剂,可用于润湿剂或发泡剂、分散剂、乳化剂和洗涤剂及其它应用。
本公开的化合物可用于上述应用和一些进一步的特殊应用(例如表面处理,例如个人毛发护理产品)两者,并且还可以用于产生防水表面。
本文公开的化合物在制剂中使用的量可低至约0.001重量%、约0.05重量%、约0.1重量%、约0.5重量%、约1重量%、约2重量%或约5重量%,或者高至约8重量%、约10重量%、约15重量%、约20重量%或约25重量%,或者在任何两个前述值之间所定义的任何范围内。
