The optimum reaction conditions were found finally. The results showed that the suitable conditions are under methanol solvent reaction temperature 40℃,the concentration of catalyzer TS-1 0.6%.,reaction time 60 minutes,propylene pressure 0.4Mpa under methanol solvent.Under Supercritical fluid system,the reaction temperature was 33.7℃(supercritical and near critical temperature),the reaction pressure was 7.58Mpa(near critical pressure and critical pressure range. propylene ), propylene pressure 0.65Mpa, reaction time 45min, cosolvent molality 4%.

而超临界体系下反(来源：4e56ABC论文网www.abclunwen.com)应温度适宜在近超临界和临界温度(33.7℃)以上，反应压力也是接近临界压力或者处于临界压力范围(7.58Mpa)，丙烯压力是0.65Mpa，反应时间45min，共溶剂甲醇摩尔浓度4%，在此反应条件下，反应的转化率98%，选择性96%，收率94%，与传统条件相比较，收率提高了20%左右。

15K. It is shown that two main factors, pressure and the polarity of the mixture, influence the EAA tautomerism.

结果表明，EAA的酮式-烯醇式异构化平衡常数随共溶剂极性的增加而减小。

On the basis of the former results, Miscibility of unseparated reaction solution with varied resins were investigated by means of co-solvent method and the glossiness of the film method. The miscibility of 344# acrylic resin with the mixture was better than others, when the ratio of the mixture to 344# acrylic resin was one to ten, the miscibility attained best, and the glossiness of the film was 100 percent.The effect of miscibility and molecular weight on delaminating rate were investigated by the co-solvent method.

Dipropyl ether will be recovered in the distillate using 1-pentanol.

使用1-戊醇。N.N-二甲基甲酰胺和2-乙氧基乙醇作为共溶剂时二丙醚将在馏分中回收。

In this study, the vapour–liquid equilibria behaviour of the binary systems dipropyl ether + 2-ethoxyethanol and 1-propyl alcohol + 2-ethoxyethanol and the ternary system dipropyl ether + 1-propyl alcohol + 2-ethoxyethanol was experimentally investigated with the aim of testing the feasibility of using 2-ethoxyethanol as an entrainer to the extractive distillation.

本文研究了2种二元体系（1：二丙醚+ 2-乙氧基乙醇；2：1-丙醇+ 2-乙氧基乙醇）和1种三元体系（二丙醚+ 1－丙醇+ 2-乙氧基乙醇）和的气液平衡行为，旨在测试2－乙氧基乙醇是否适合作为萃取性蒸馏的共溶剂。

The application of such solvent effects to the kinetically controlled peptide synthesis, however, has only recently been exploited.

试验结果表明，在所研究的几种单相共溶剂体系中，木瓜蛋白酶的酰胺酶活性都得到了不同程度的抑制，有些情况下甚至完全被抑制，而酯酶活性则保留了单水相中的全部或部分。

Through measuring the solubility,stability and hydrolyzation property,the effect of additives on the characteristics of concentrated aqueous reactive blue P-3R was investigated. The results showed that among the four kinds of organic solvents,N-methyl pyrrolidone was the best one and its optimum dosage 10%. Na_ 2 HPO_ 4 /NaH_ 2 PO_ 4 was a better buffer and its optimum dosage was 3%.

通过对液态染料溶解性、稳定性、耐水解程度等的测试，综合考察了添加剂的种类及用量对高浓度液态活性艳蓝P-3R性能的影响，结果表明在所考察的四种有机共溶剂中，N-甲基吡咯烷酮的效果最好，且其最佳用量为10%；缓冲溶液中Na2HPO4/NaH2PO4的效果较好，最佳用量为3%。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
