制备方法与用途

化学性质
硬脂酸铝又名十八酸铝，化学式为 ((C_{17}H_{35}COO)_3Al) ，分子量为 877.35。纯品是白色粉末，相对密度为 1.070，熔点为 115℃；不纯品则呈淡黄色粉末状。硬脂酸铝不溶于水、乙醇和乙醚，但能溶于碱、松节油、矿物油、石油、煤油及苯等有机溶剂中。它还能形成晶状吡啶配合物。遇强酸时会分解成硬脂酸和相应的铝盐。由于具有良好的吸湿性和稳定性，硬脂酸铝常被用作木材防腐剂，可以有效防止木材腐朽和虫蛀。

用途
硬脂酸铝是一种重要的有机金属盐，常用作助剂和添加剂，在化妆品、制药、涂料、油墨、塑料、橡胶等行业中发挥着重要作用。它具有稳定、乳化、吸湿、防腐、防火等功能。本产品可用于聚氯乙烯塑料的热稳定剂和润滑剂，作为金属防锈剂的原料、建筑材料的防水剂、油漆工业的防沉剂、油墨的抛光剂、化妆品的增稠剂以及润滑油的增厚剂等。在涂料中，硬脂酸铝用作平滑剂及增稠剂，并能改善涂膜触变性。金属皂是早期常用的消光剂之一，主要包括一些金属硬脂酸盐，如硬脂酸铝、硬脂酸锌、硬脂酸钙和硬脂酸镁等，其中硬脂酸铝应用最为广泛。

生产方法
硬脂酸铝可通过以下两种方式制得：一是将硬脂酸钠稀溶液与稀硫酸铝溶液作用；二是将硬脂酸钠溶液与醋酸铝共热。

  A method for making metal (8-quinolinolate) complexes from air and moisture stable reagents is described. For example, the making of aluminum tris(quinolinolates), such as tris(8-hydroxyquinolinato), from aluminum (III) carboxylates, such as aluminum lactate and aluminum stearate, is described. Examples of bis and tris metal (8-quinolinolates) as well as single and mixed ligand complexes are given.

• A novel stearate melting method for synthesizing highly reactive YAG nanopowders
  作者：Jinsheng Li、Xudong Sun、Shaohong Liu、Xiaodong Li、Di Huo、Ji-Guang Li、Qi Zhu、Mu Zhang、Yuanhua Sang、Hong Liu

  DOI：10.1016/j.jallcom.2013.09.094

  日期：2014.2

  Ultrafine YAG powders were synthesized by a novel stearate melting method, in which yttrium stearate and aluminum tristearate, having similar physical and chemical properties, were co-melted and then calcined to produce fine YAG nanopowders. This method has the advantages of precise control of Y: Al ratio, homogeneous mixing of cations at atomic level, fine particle size, and good particle dispersion. The formation mechanism of the precursor and the YAG nanopowder was studied by means of XRD, FT-IR, TGDTA, BET and FE-SEM. Pure YAG nanopowder can be obtained by calcining the co-melted precursor at a relatively low temperature (750 degrees C), much lower than those of the traditional solid-state reaction method and various wet chemical synthesis methods. The resultant YAG powders are well dispersed and have excellent sinterability. For the YAG powder calcined at 1000 degrees C, the green compact has the maximum shrinkage rate at about 1450-1550 degrees C and a total shrinkage of similar to 16.70% during constant heating rate sintering. The compact can be sintered to 99.4% of the theoretical density at 1600 degrees C. The prepared YAG powder can be sintered into transparent ceramics at 1700 degrees C for 5 h by vacuum sintering.
