Piperidinecarboxylic acid is used as the raw material and acetic acid as the acylating agent, followed by the addition of some acetic anhydride in the later stage to get an important organic intermediate n-acetylpiperidine-4 carboxylic acid in the yield of 92%. Toluene is used as the solvent instead of sulfinyl chloride in the acyl chlorination to produce n-acetylpiperidine-4-carbonyl chloride with the yield of 97%.

It was shown that these two strains both can utilize benzoate as sole carbon source and the maximum tolerance of benzoate are 1.7% and 1.600, respectively; These two strains both can grow on benzene, toluene, xylene, phenol, benzyl alcohol of as sole carbon source. Pfluorescens PFO1 can degrade dianiline, 3,5-dinitrosalicylic acid, p- dimethylaminobenzaldehyde while P. aeruginosa ATCC27853 can utilize 3,5-dinitrosalicylic acid, p- dimethylarninobenzaldehyde.

结果表明，两种菌都能在以苯甲酸钠为唯一碳源的基础培养基上生长，并且，对苯甲酸钠的耐受性分别达到1.7％和1.6％；两种菌都能以适当浓度的苯，甲苯，二甲苯，苯酚，苯甲醇为唯一碳源生长；荧光假单胞菌能以二苯胺，对二甲氨基苯甲醛，3，5-二硝基水扬酸为唯一氮源生长；铜绿假单胞菌能以3，5-二硝基水扬酸，对二甲氨基苯甲醛为唯一氮源生长。

In this thesis, this system is used for epoxidation of propylene and styrenewith good results. The solvent effect is investigated for epoxidation of styrene. In the mixedsolvent of dimethyl phthalate / TBP or phenyl ether / TBP, the selectivity for styreneoxide is good but the conversion of styrene is low due to the coordination to thecatalyst of the solvent. When part of dimethyl phthalate or phenyl ether is replacedby toluene, the conversion increases and the selectivity keeps constant.

邻苯二甲酸二甲酯或二苯醚等与磷酸三丁酯的混合溶剂中环氧化的选择性较高，但由于溶剂对催化剂的配位作用抑制了催化剂的活性，苯乙烯转化率很低；当部分的邻苯二甲酸二甲酯或二苯醚被甲苯取代后，苯乙烯的转化率提高，生成环氧苯乙烷的选择性不变。

Kinetics of hydroxyl-terminated polybutadiene/ phenyl isocyanate, bonding agent (BA-5)/PI and antioxidant H/PI were studied in toluene/dimethyl sulphoxide solution. The rate constants and the activation parameters were calculated. The results show that the reactionary rate of these three active hydrogen components decreased in same condition.
