  1-Germatranol Hydrate 与二羧酸的反应

  摘要：

  1-germatranol 水合物与丙二酸、丁二酸、马来酸、软木酸、癸二酸和丁二酸的双三甲基甲硅烷酯，以及双(germatran-1-yl)oxane 与丁二酸在乙腈、水、甲醇和二甲亚砜中的反应进行了研究。在有机溶剂中，形成单羧基和双羧基取代的 1-germatranol，其与 1-germatranol 一样，在酸性介质中与水可逆地水解。由于蒸发和拓扑化学反应从反应混合物中除去水会增加酯化 1-germatranol 的产率。

  A formaldehyde free co-binder solution formed by using a polyol to crosslink polycarboxylic acid and a polyacid monomer is provided. In forming the co-binder solution, the polyacid monomer and the polyol are mixed in any conventional device with heat and agitation for a period of time sufficient for the chemicals to react and form a reaction product. The resultant product is then admixed with polycarboxylic acid to form a co-binder solution. In a preferred embodiment, the polyacid is maleic anhydride and the polyol is triethanolamine.

  An additive for increasing an early activity index of nickel slag and a preparation method thereof, belonging to the field of additive technologies, are provided. The preparation method includes: successively adding maleic anhydride and triethanolamine to a reactor; setting the heating temperature to 50° C. for reaction, where a large amount of heat is released during the reaction; when the reaction temperature decreases to 60° C. after heat is released in the reaction, allowing triethanolamine maleate to react with a solution of bromine in carbon tetrachloride; adding water to the mixture, where the weight percentage content of the added water is 60%; separating and removing carbon tetrachloride from water; and conducting uniform stirring to obtain the additive. A molar ratio of the maleic anhydride, the triethanolamine, and bromine is (0.2-1):1:(0.2-1), and a molar ratio of the maleic anhydride to the bromine is 1:1.
