    • Electrochromic coating solutions are prepared by allowing hydrated tungsten oxides to react with an admixture of hydrogen peroxide and an organic acid or anhydride. The intermediate tungsten peroxy acid is esterified by heating under reflux with alcohol to produce a precursor solution including peroxyester tungsten derivatives. The precursor solution can be used to apply a coating to the conductive surface of the substrate by dip coating, spraying or spin coating. The coating is then dried and is heated to a sufficiently high temperature to convert the tungsten peroxyesters to amorphous tungsten oxide with good electrochromic properties.
    • 通过使水合钨氧化物与过氧化氢和有机酸或酸酐的混合物反应来制备电致变色涂层溶液。 中间体过氧酸通过与醇回流加热而酯化,生成包含过氧酯钨衍生物的前体溶液。 前体溶液可用于通过浸涂,喷涂或旋涂将涂层施加到基材的导电表面。 然后将涂层干燥并加热至足够高的温度,以将钨过氧化物转化为具有良好电致变色性质的无定形氧化钨。

    • A number of solid peroxyacids are obtained by precipitation from a highly acidic reaction media in which they are prepared by sulphuric acid catalysed reaction of a corresponding carboxylic acid with hydrogen peroxide. The physical characteristics and purity of the precipitated solids are controlled by the method of precipitation. A product having a balance of acceptable filtration and washing rate with acceptable product purity is obtained by precipitating in the presence of a surfactant at a low concentration, such as in the range of from about 0.02 % to 0.5 % by weight, based on the weight of the diluted reaction mixture. The dilution process can be carried out in a single stage process, batchwise or continuously, or in a multi stage dilution process in which the first stage preferably dilutes to the point at or around when precipitation appears and is conducted rapidly, and subsequent dilution is conducted more slowly. Dilution can be conducted using water/ice, optionally containing to a lower concentration sulphuric acid and/or dilute hydrogen peroxide. The invention process is particularly suitable for the preparation of particulate poorly water-soluble diamidoperacids, including specifically terephthaloyl diamidoperoxycaproic acid of formula HO3C-(CH2)5-NH-CO-C6H4-CO-NH-(CH2)5-CO3H or the corresponding monoperacid, which can be obtained in a new crystalline form in the presence of sufficient surfactant. The invention process can be tailored to produce particulate peracid derivatives of phenylenediamidoalkylenecarboxylic acids having increased particle size, such as from 10 to 40 mu .
    • 通过从高度酸性的反应介质中沉淀获得许多固体过氧酸,其中它们通过相应的羧酸与过氧化氢的硫酸催化反应制备。 沉淀固体的物理特性和纯度由沉淀法控制。 通过在低浓度的表面活性剂的存在下,例如在约0.02重量%至0.5重量%的范围内,以重量为基准沉淀,得到具有可接受的过滤和洗涤速率与可接受的产物纯度的平衡的产物 的稀释反应混合物。 稀释过程可以在单阶段过程中分批或连续进行,或在多阶段稀释过程中进行,其中第一阶段优选稀释至沉淀出现时或周围,并迅速进行,随后进行稀释 更慢 稀释可以使用水/冰进行,任选地含有较低浓度的硫酸和/或稀释的过氧化氢。 本发明方法特别适用于制备颗粒状弱水溶性二酰氨基酸,包括具体式为HO3C-(CH2)5-NH-CO-C6H4-CO-NH-(CH2)5-CO3H的对苯二酰二酰基过氧己酸或相应的 单酸,其可以在足够的表面活性剂存在下以新的结晶形式获得。 本发明方法可以被定制以产生具有增加的粒度的苯二胺二亚烷基羧酸的颗粒过酸衍生物,例如10-40微米。
