一般描述

硬脂酸 (SA) 是一种直链脂肪酸。在锗表面形成有序的单层 LB 膜。用傅里叶变换红外 (FTIR)-衰减全反射 (AR) 光谱对这些 LB 膜进行了研究。[1]

报道了以负载型钯催化剂,将选择性 >98% 的水杨酸转化为脱氧的 C17 产物。[2]相更改储能材料具有无毒、熔化温度方便等优点,是一种很有前途的相变储能材料。而且,它在经历相更改时表现出几乎可以忽略不计的过冷。[3]

应用

在溶胶-凝胶法制备纳米微胶囊相更改材料 (NEPCMs) 过程中,硬脂酸可作为核心组分。[3]
硬脂酸在介孔固体酸催化剂存在下可发生酯化反应生成硬脂酸甲酯。[4]由于其防水能力,STA 可用于赋予各种表面超疏水性。[5]STA 也可用于制备硬脂酸自组装膜。[6]
