Surfactant compositions containing compounds according to structure (I), and methods of making them, are disclosed. The compounds provide reduced dynamic and equilibrium surface tension, good solubility, moderate foaming, and good cleaning performance. The methods for making them involve reaction of N-(polyhydroxyalkyl)-alkylamines with dinitriles, dialdehydes, or acetals or hemiacetals of dialdehydes in the presence of hydrogen and a transition metal catalyst.
In structure (I), x is an integer from about 1 to 12, R
1
and R
2
are independently C3-C30 linear alkyl, cyclic alkyl, branched alkyl, alkenyl, aryl, alkylaryl, alkoxyalkyl, and dialkylaminoalkyl; and R
3
and R
4
are independently hydrogen or a pyranosyl group such as α-D-glucopyranosyl, β-D-glucopyranosyl, or β-D-galactopyranosyl.
含有结构(I)中化合物的表面活性剂组合物以及制备它们的方法已被披露。这些化合物提供了降低的动态和平衡表面张力、良好的溶解性、适度的起泡性能和良好的清洁性能。制备它们的方法涉及N-(多羟基烷基)-烷基胺与二腈、二醛或二醛的缩醛或半缩醛在氢气和过渡金属催化剂存在下的反应。在结构(I)中,x是约1到12之间的整数,R1和R2独立地为C3-C30线性烷基、环烷基、支链烷基、烯烃、芳基、烷基芳基、烷氧基烷基和二烷基氨基烷基;R3和R4独立地为氢或吡喃基团,如α-D-葡萄糖吡喃基、β-D-葡萄糖吡喃基或β-D-半乳糖吡喃基。
