The curing process of epoxy resin with maleic anhydride has been examined with infrared spectroscopy, by following the functional group changes occuring in different curing stages at different temperatures. It has been found that the increase of molecular weight and the formation of cross-linkages in the epoxy resin are attained primarily via the esterification reaction, that is, the anhydride first reacts with the hydroxyl group in the resin to form a mono-ester and the newly formed carboxylic group reacts...

The curing process of epoxy resin with maleic anhydride has been examined with infrared spectroscopy, by following the functional group changes occuring in different curing stages at different temperatures. It has been found that the increase of molecular weight and the formation of cross-linkages in the epoxy resin are attained primarily via the esterification reaction, that is, the anhydride first reacts with the hydroxyl group in the resin to form a mono-ester and the newly formed carboxylic group reacts with an epoxy group to give a diester and a new hydroxyl group which can itself react with the anhydride. Under the influence of heat, the maleate structure formed in the esterification tends to isomerize into fumarate. This cis-trans isomerization reaction is temperature-sensitive, but the extent of reaction is not appreciable below 60℃. At a curing temperature of 180℃ or higher, the carbon-carbon double bonds in the maleate structures may undergo addition polymerization and thermal oxidation, resulting in the formation of new carbonyl and hydroxyl groups.

通过对环氧树脂和顺丁烯二酸酐在加热固化过程中红外光谱演变情况的观察,阐明了树脂在不同固化阶段和不同固化温度所进行的各类反应和相应的结构变化。在固化过程中使树脂的分子量增大和形成交联结构的主要反应是酯化反应。Fisch等提出的醚化反应在红外光谱中没有得到证实。树脂在酯化反应中生成的顺丁烯二酸酯的结构受热的影响会产生顺、反异构化反应。反应的进程取决于固化温度。在180℃加热已固化的树脂将导致部分碳-碳双键和剩余环氧基的减少,同时产生新的羟基和羰基。

A gas chromatographic method, which utilizes a glycerol column connected in series with a silicone oil column, has been developed for the analysis of liquid phase byproducts in butadiene synthesis from ethanol. Ethanol and water, the main components, are separated from the other components by back-flushing through the glycerol column. Further resolution of the components free from water and ethanol is carried out on silicone oil column. By means of the functional group colour reaction, treated the vapour...

A gas chromatographic method, which utilizes a glycerol column connected in series with a silicone oil column, has been developed for the analysis of liquid phase byproducts in butadiene synthesis from ethanol. Ethanol and water, the main components, are separated from the other components by back-flushing through the glycerol column. Further resolution of the components free from water and ethanol is carried out on silicone oil column. By means of the functional group colour reaction, treated the vapour sample with chemical reagents in syringe, and the addition of supposed constituents, six compounds, i.e., acetaldehyde, ethyl ether, acetone, valeraldehyde, butyraldehyde, and ethyl acetate have been identified, and the former four constituents are quantitatively estimated by the absolute peak height method.
