乙酸戊酯

Through the experiments and result analysis,this paper discusses the factors influencing the catalytic synthesis of isoamyl acetate with the crystal aluminum chloride as the catalyst.

通过实验及结果分析，讨论了影响结晶三氯化铝催化合成乙酸异戊酯反应的因素。

The activation energy of the reaction with solid super acidic catalyst is obviously lower than that of the reaction without catalyst, Sugesting that S2O8(superscript 2-)/TiO2-Al2O3 is the the effective catalyst of the synthesis of amyl acetate.

固体超强酸S2O82-/TiO2-Al2O3使反应活化能明显降低，是乙酸异戊酯合成的有效催化剂。

The esterification of acetic acid and n amyl alcohol by using heteropoly acid as catalyst was studied.

乙酸正戊酯[1]是一种无色透明的液体，可用作喷漆的溶剂和稀释剂，也用作香料和化妆品的原料以及木材粘合剂的溶剂。

In the end, the extractive distillation method was applied to separate and purify the binary azeotrope mixture, methanol-dimethyl carbonate. The isoamyl acetate was used as extractant and the two tower system was introduced to continuous extractive distillation operation. The results show a better separation effect.

最后采用萃取精馏的方法，对甲醇-碳酸二甲酯的二元共沸混合物进行了分离提纯研究，以毒性较低的乙酸异戊酯为萃取剂，采用两塔连续萃取精馏操作，结果表明，分离效果比较理想。

Phosphotungstic acids (PW12) supported on activated carbon were prepared, characterized by XRD, IR and N2 adsorption, and used as the catalyst for synthesis of n-amyl chloroacetate.

制备了活性炭为载体负载型磷钨酸催化剂，并采用XRD、IR、N2吸附等手段进行了表征。将其用作合成氯乙酸正戊酯催化剂。

The emphasis was on chemical properties,application,main production methods,market,and prospects of main deriva- tives of acetaldehyde such as ethyl acetate,pentaerythritol,glyoxal,peracetic acid, crotonaldehyde and pyridine.

介绍了国内外乙醛及其主要衍生物的生产技术发展及其市场供需状况，尤其对乙醛主要衍生物乙酸乙酯、季戊四醇、乙二醛、乙醛酸、丁烯醛、吡啶的化学性质与用途、主要生产方法、市场供需状况及开发前景作详细介绍和分析。

In four flavor models, isoamyl alcohol model and ethyl acetate model have good capacity for simulation and prediction, whereas acetaldehyde model and diacetyl model do not.

在建立的4个风味物质模型中，异戊醇和乙酸乙酯模型的仿真能力和预测能力都比较强，双乙酰和乙醛模型的仿真能力和预测能力都比较差，需要进一步研究。

The effects of catalyst synthesis and esterification reaction conditions on the yield of the isoamyl acetate were investigated.

将该催化剂用于醇酸反应制备乙酸异戊酯，考察了反应条件对酯化率的影响。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
