An analysis was made on the curing reaction of Zili-4 adhesive composed of epoxy resin 6l8, tertiary amine-catalyzed dicyandiamide and reinforcer polysulfone resin by using CDR-1 Differential Scanning Calorimetry(DSC). Two interrelated analytical methods, Ellerstein's and Kissinger's methods, were used to process dynamic DSC data for characterizing the curing reactivity or the kinetic parameters such as overall activation energy E, reaction order n,total reaction heat △Ht, curing reaction extent...

An analysis was made on the curing reaction of Zili-4 adhesive composed of epoxy resin 6l8, tertiary amine-catalyzed dicyandiamide and reinforcer polysulfone resin by using CDR-1 Differential Scanning Calorimetry(DSC). Two interrelated analytical methods, Ellerstein's and Kissinger's methods, were used to process dynamic DSC data for characterizing the curing reactivity or the kinetic parameters such as overall activation energy E, reaction order n,total reaction heat △Ht, curing reaction extent a, and reaction time t. Ellerstein's method was applied to a thorough differential-integral analysis of single DSC curve to evaluate the kinetic parameters and Kissinger's method to multiple USC curves obtained at various heating rates to evaluate the overall activation energy E,regardless of the reaction order n, whille the value of n was determined according to the shape index (Si-a/b) in Kissinger's method. In addition. Arrhenius' equation was applied to processing static DSC data for comparing with dynamic methods. APPLE-Ⅱ micro-computer was applied to process experimental data. Kinetic analysis of curing reaction of zili-4 adhesive showed that the reaction order n is substantially affected fay heating tate, which manes n redueed from 1.3 at slow scanning rate to 1,1 at higher seaning rate. Finally, three temperatures, gelating temperature Tge , caring temperature Tcure and treating temperature Ttreal were determined by extrapolating of T-φ curves shown in Fig. 9.

Ab initio molecular orbital method has been employed, in this paper, to study the mechanism of the hydrolysis of acetylcholine. First of all, the potential energy surface of the reaction system has been investigated at HF/6 - 31G level, and two transition states and an intermediate linking the two transition states have been found. The optimized geometries have been used to perform further single point energy calculations at HF/6 - 31G * * level. It has been shown that there existed different intramolecular hydrogen bonding in two four - center cycles of the two transition states,and that during the hydrolysis of acetylcholine,the fission took places at the bond between the carbonyl carbon and the ester oxygen. Finally, the self- consistent - reaction - field (SCRF) procedure based on the Quantum Onsager model has been applied to the energy calculations on all the reactions , transition states , intermediate and products at the HF / 6 - 31G * * level in order to work out the energy barriers and the total reaction heat involving the solvent effect.

本文对乙酰胆碱水解反应历程进行了从头算分子轨道研究.首先,我们在RHF/6—31G级别上研究了乙酰胆碱的水解反应的势能面,找到了反应过程中的两个过渡态和连接这两个过渡态的中间体.然后进行了RHF/6—31G**级别上的单点能量计算.优化结果表明在两个过渡态中都包含有四元环状结构,而且,两个过渡态的四元环中存在着不同的分子内氢键.计算结果还表明,乙酰胆碱最终分解成胆碱和乙酸盐部分时,酯键的断裂发生在羰基碳和酯基氧之间.最后,进一步考虑溶剂化效应,我们还运用量子Onsager模型,在RHF/6-31G**级别上对整个水解反应的反应物、产物、中间体和过渡态分别进行了从头算自洽反应场能量计算,求出了包含溶剂化效应在内的反应的能垒及总反应热.

Recently, more and more gangues are used as raw materials to make bricks. But the control of the sintering temperature is still a problem. Through the exploratory investigation about the reasonable sintering temperature control of the high aluminum gangue in Yunnan province, it is noted that there should be an estimation about the total reaction heat, and heat consumption for different kinds of gangues and it is too difficult to ensure the bricks' quality by using a single sintering mode. This is...

Recently, more and more gangues are used as raw materials to make bricks. But the control of the sintering temperature is still a problem. Through the exploratory investigation about the reasonable sintering temperature control of the high aluminum gangue in Yunnan province, it is noted that there should be an estimation about the total reaction heat, and heat consumption for different kinds of gangues and it is too difficult to ensure the bricks' quality by using a single sintering mode. This is also valuable for the future.

利用陈煤矸石烧结砖愈来愈受到人们的重视 ,但对烧结温度控制的问题 ,尚未引起人们的关注。文章通过对云南省高铝煤矸石烧结砖坯体进行合理温度控制的探讨 ,提出了针对不同的陈煤矸石原料必须估算其总反应热或耗热量。如果对所有陈煤矸石砖坯体只按一种烧结模式进行烧结 ,则很难保证煤矸石烧结砖的质量 ,同时也提出这是今后利用煤矸石烧结砖值得认真研究的问题。
