    • A process for the manufacture of .beta.-isobutyrylaminocrotonic acid amide by reacting .beta.-aminocrotonic acid amide with dimethylketene in the liquid or gaseous state without the application of external heat at temperatures in the range of from room temperature to 70.degree. C. The dispersion medium used is an organic solvent having a boiling point above 40.degree. C. that may contain up to 0.1 mole of water and 0.2 to 2 moles of a carboxylic acid having 1 to 4 carbon atoms per mole of .beta.-aminocrotonic acid amide. If the dimethylketene is added undiluted the reaction is carried out in the absence of oxygen and in the presence of a protective gas atmosphere. The .beta.-isobutyrylaminocrotonic acid amide is obtained in the form of two stereoisomers (Z- and E-forms), which differ as regards their melting point and their solubility in organic solvents. On heating to 40.degree. C., the E-form is converted into the Z-form.
    • 通过使β-氨基巴豆酸酰胺与液体或气态的二甲基烯酮反应制备β-异丁酰氨基巴豆酸酰胺的方法,而不需要在室温至70℃的温度范围内施加外界热。使用的分散介质 是沸点高于40℃的有机溶剂,其可含有至多0.1摩尔水和0.2至2摩尔每摩尔β-氨基巴豆酸酰胺具有1至4个碳原子的羧酸。 如果未稀释地加入二甲基烯酮,则反应在不存在氧的情况下和在保护气体气氛存在下进行。 β-二异丁酰氨基巴豆酸酰胺以两种立体异构体(Z-和E-型)的形式获得,它们的熔点和它们在有机溶剂中的溶解度不同。 加热至40℃时,将E型转化成Z型。

    • An improved process for the manufacture of 2-isopropyl-4-methyl-6-hydroxypyrimidine, starting from 3-aminocrotonic acid amide and an acylating agent, without isolating the intermediately formed 3-isobutyrylaminocrotonic acid amide. In a first process step, the acylation is carried out with excess isobutyric acid anhydride in the presence of an alkali metal salt of isobutyric acid at temperatures of from 50.degree. to 120.degree. C. and in the absence of a solvent. In a second process step, the cyclization is carried out in the resulting reaction mixture by the addition of an aqueous alkali metal hydroxide solution at temperatures of from 80.degree. to 105.degree. C., and then the hydroxypyrimidine is isolated in known manner. The total quantities of alkali metal hydroxide added in the second process step are such that they are sufficient both for the neutralization of the isobutyric acid present in the reaction mixture and also for the cyclization. Less than 1 mole of alkali metal hydroxide per mole of the 3-aminocrotonic acid amide originally used is used for the cyclization itself.
    • 从3-氨基巴豆酸酰胺和酰化剂制备2-异丙基-4-甲基-6-羟基嘧啶的改进方法,而不分离中间形成的3-异丁酰氨基巴豆酸酰胺。 在第一工艺步骤中,在50-120℃的温度和不存在溶剂的条件下,在异丁酸的碱金属盐存在下,用过量的异丁酸酐进行酰化。 在第二个工艺步骤中,通过在80℃至105℃的温度下加入碱金属氢氧化物水溶液在所得反应混合物中进行环化,然后以已知的方式分离出羟基嘧啶。 在第二工艺步骤中加入的碱金属氢氧化物的总量使得它们对于中和反应混合物中存在的异丁酸以及环化都是足够的。 最初使用的每摩尔3-氨基巴豆酸酰胺少于1摩尔碱金属氢氧化物用于环化本身。

    • The invention provides mixed aromatic vinyl-1,3-diene polymers stabilized by a protective colloid and present in the form of aqueous polymer dispersions or polymer powders redispersible in water as adhesives for porous substrates. The polymer dispersions and the polymer powders are obtained by emulsion polymerization of a mixture containing: a) 20 to 80 percent by weight of one or more vinylaromatics; b) 19.9 to 79.9 percent by weight of one or more 1,3-dienes; c) 0.1 to 15 percent by weight of one or more comonomers from the group consisting of N-methylolacrylamide, N-methylolmethacrylamide and the N-(alkoxymethyl)-acrylamides and N-(alkoxymethyl)-methacrylamides with a C1 to C6-alkyl radical. The sum of the above percentages adds up to 100% by weight. Emulsion polymerization is carried out in the presence of one or more protective colloids and without emulsifiers, optionally followed by drying of the resulting aqueous polymer dispersion.
