Tri-acylates of lanthanum and cerium(III) are quantitatively precipitated by the reaction of their nitrates or chlorides with excess of sodium soaps (laurate, palmitate, stearate) in aqueous solutions. These salts are not hydrolysed by water and are soluble in hot benzene from which pure samples may be crystallized. Molecular weight measurements show them to be monomeric in benzene. Viscosities of
镧和铈的三酰化物(硝酸盐)是通过硝酸盐或氯化物与过量的钠肥皂(月桂酸酯,棕榈酸酯,硬脂酸酯)在水溶液中的反应而定量沉淀的。这些盐不被水水解,可溶于热苯,从中可以结晶出纯净的样品。分子量测量表明它们在苯中为单体。已经测量了它们的苯溶液的粘度,并且还研究了它们的热重行为。制备混合氯化物或硝酸盐的尝试未成功。
