Abstract

A novel hydroxamic acid, N-hydroxy-9,10-epoxy group-octadecanamide (N-OH-9,10-O-ODA), was synthesised by modifying the structure of oleic acid. The carboxyl group of oleic acid was converted into an N-hydroxy amide group, and an epoxy group was introduced into its structure. N-OH-9,10-O-ODA was used as a novel collector in the flotation separation of spodumene from one of its associated gangue minerals, specifically albite. N-OH-9,10-O-ODA exhibits remarkable selectivity, with a stronger affinity for collecting spodumene particles compared to albite particles. Zeta potential measurements and X-ray photoelectron spectroscopic analysis reveal that the adsorption quantity of N-OH-9,10-O-ODA on spodumene surface is comparable to that on albite surface. First-principles calculations demonstrate the diverse adsorption configurations of N-OH-9,10-O-ODA on surfaces of spodumene and albite, leading to its distinct collecting abilities for spodumene and albite particles.

新型表面活性剂 N-羟基-9,10-环氧基十八酰胺：第二部分。其合成及其在浮选分离黝帘石和白云石中的应用

通过改变油酸的结构，合成了一种新型羟肟酸--N-羟基-9,10-环氧基十八烷酰胺（N-OH-9,10-O-ODA）。油酸的羧基被转化为一个 N-羟基酰胺基团，并在其结构中引入了一个环氧基团。N-OH-9,10-O-ODA被用作一种新型捕收剂，用于浮选分离黝帘石和其中一种伴生煤矸石矿物，特别是白云石。N-OH-9,10-O-ODA具有显著的选择性，与白云石颗粒相比，它对收集黝帘石颗粒具有更强的亲和力。Zeta 电位测量和 X 射线光电子能谱分析表明，N-OH-9,10-O-ODA 在黝帘石表面的吸附量与在白云石表面的吸附量相当。第一性原理计算证明了 N-OH-9,10-O-ODA在黝帘石和白云石表面的不同吸附构型，从而导致其对黝帘石和白云石颗粒的不同收集能力。
