According to the results of the former study in our laboratory, trans-1, 2-cyclohexanediol is produced with a lot of acids and water, for extraction of trans-1, 2-cyclohexanediol from the solution, ethyl acetate and butyl acetate were used as extraction reagents, the solubility data of the trans-1, 2-cyclohexanediol in corresponding mixed solvents of some sorts of acetates and water are needed.
根据本实验室前期研究结果可知,反式-1,2-环己二醇是在酸性和大量水存在的条件下得到的,为了把反式-1,2-环己二醇从反应液中萃取出来,本工艺所采用的萃取剂是乙酸乙酯和乙酸丁酯,需要获得反式-1,2-环己二醇在这些酯类与水混合溶剂中的溶解度数据,因而对反式-1,2-环己二醇进行相关固液相平衡的研究是非常迫切和必要的。

Objective: Cyclooxygenase-2 (COX-2) and peroxisome proliferators-activated receptor-gamma play very important roles in occurrence, progression and prognosis of tumor. But the definite effects and mechanisms of specific COX-2 inhabitor and PPARγagonist on the prevention and cure of pancreatic cancer have not been fully elucidated.
目的:近年来研究表明,环氧化酶-2(cyclooxygenase-2, COX-2)和过氧化物酶体增殖因子活化受体γ在肿瘤发生、发展中起十分重要的作用,但特异性COX-2抑制剂和PPARγ激动剂对胰腺癌的防治作用及其机制尚未十分明了。

The microorganisms was domesticated by adding a certain amount of lead in the soil, and three lead-tolerant strains including Pb-R-1, Pb-R-2 and Pb-H-3 accordingly originating from 300 mg/L, 750 mg/L and 900 mg/L lead medium were isolated with a series of PDA medium of different lead concentrations. Through the identification, Pb-R-2 was confirmed as Aspergillus sp., Pb-R-3 as Penicillium sp. The trials of transferring culture showed that all strains had the stable heredity of lead tolerance in different composition PDA medium.

The mechanism of dioxygen oxidation of NTS to DNS in alkali solution under mild condition was inquired into. The result showed that the key step in the preparation of DNS from NTS was the formation of 4-nitro-2-sulfobenzyl anion as a result ionization of NTS in strong alkali and then oxidization to 4-nitro-2sulfobenzyl radical by activated dioxygen.
探讨了在温和条件下于碱的水溶液中氧气液相氧化4-硝基甲苯-2-磺酸制取4,4'-二硝基二苯乙烯-2,2'-二磺酸的反应机理,发现4-硝基甲苯-2-磺酸在碱作用下发生离子化生成4-硝基-2-磺酸基苄基阴离子,然后被活化的分子氧氧化成4-硝基-2-磺酸基苄基自由基是反应的关键步骤。
