Results indicate that as the molecular mass of polyethylene glycol increases, the conductance is increased obviously, and the surface tension is decreased from 36.28 mN/m to 31.30 mN/m, while the cloud point is increased from 39.6 ℃ to 58.9 ℃. Their emulsifying abilities to BA, MMA and BMA are superior to that of OP-10, and the surfactants is homopolymerize or copolymerize with acrylate at 70 ℃ under the initiation of AIBN.

On July 31, 2008, xiaoding is found after Xiaohuang comes off work, say the company was kept by him that day code of game Zhang name, want to log onto the Zhang date of the company only, can get play money easily, by Zhang of his demon animal world from the company money of play of go on a journey turns to sell counterchange to become ready money inside date.

因此，小丁和小曾就商量着辞职后专职在网上买卖游戏币，却苦于资金不够。2008年7月31日，小黄下班后找到小丁，称当天公司由他保管游戏账号密码，只要登录公司的账号，就可以轻松得到游戏币，由他从公司的魔兽世界账号内转出游戏币卖掉换成现钱。

Acid--aldehyde polymer tanning agent P (acrylic acid-crotonaldehyde was copolymerizaed from acrylic acid and crotonaldehyde in water and its structure was characterized by IR,〓C-NMR and DSC.

以丙烯酸、丁烯醛为共聚单体，采用水溶液共聚法，合成了含醛、酸基团高分子鞣剂----丙烯酸-丁烯醛共聚物，并利用IR光谱、〓C-NMR及DSC对其结构进行了确认和表征。

Firstly, 3-ethylthiobutanal was prepared from crotonaldehyde reacting with ethanehiol in triethylamine with high yield. Secondly, methyl acetoacetate was converted to 6-ethylthiohept-3-en-2-one by three steps via hydrolysis, condensation with 3-ethyltio-butanal and dehydration, then 6-ethylthiohept-3-en-2-one was cycloco ndensed with dimethyl malonate by Michael addition and Claisen condensation, followed by saponification and decarboxylation to give the intermediate of 5-(2-ethylthiopropyl)-cyclohexane-1,3-dione.

首先，以巴豆醛与乙硫醇为原料，在三乙胺的催化作用下高收率制得3-乙硫基丁醛；然后从乙酰乙酸甲酯出发，通过碱水解、与3-乙硫基丁醛缩合、脱水三步反应合成6-乙硫基-3-烯-2-庚酮，接着6-乙硫基-3-烯-2-庚酮与丙二酸二甲酯通过Michael加成和Claisen缩合成环，再通过皂化和脱羧反应生成中间体5-[2-丙基]-1，3-环己二酮；再与丙酸酐反应丙酰化，最后与0-3-氯-2-丙烯基羟胺肟化，得到目标化合物烯草酮。

Crystal structural analysis reveals that, because water molecules bond to Cu atoms, the dhbd ligand can only adopt a hydroxyl oxygen atom to bridge two reversed U-shaped subunits into a novel centrosymmetric dual-U-shaped tetranuclear Cu structure. Each U-shaped frame consists of two crystallographically distinct Cu atoms, two dpphen ligands and one coordinated water molecule.

晶体结构分析表明，由于水的配位阻断， 2，3-二羟基丁二酸根仅通过单羟基氧桥联两个U形双核亚单元形成具有一个对称中心的双U形四核结构，其中U型亚单元包含晶体学上不对称的2个Cu原子、1个2，3-二羟基丁二酸根、2个4，7-二苯基-1，10-邻菲咯啉和1个配位H2O分子。

The photocycloaddition of 1-naphthonitrile (1-NpCN) and 2,3-dimethyl-2-butene in cyclohexane or benzene gave cyclobutane 3 primarily,but that of 2-NpCN gave azetine 6 asthe major and cyclobutane 5 as the minor product in low conversion photolysis.

在低转化光解情况下，1-萘甲腈(1-NpCN)和2，3-二甲基丁烯-2在环已烷或苯中的光环加成反应主要得到环丁烷3，但2-NpCN主要得到氮杂环丁烯6和少量的环丁烷5，三氟醋酸量增加抑制1-NpCN和DMB的光环加成反应，表明TFA与基态及单激发态1-NpCN生成非光反应的复合物，它也淬灭(1-NpCN-DMB)激基复合物。

The photocycloaddn. of 1-naphthonitrile (1-NpCN) and 2,3-dimethyl-2-butene in cyclohexane or benzene gave cyclobutane I primarily, but that of 2-NpCN gave azetine II as the major and cyclobutane III as the minor product in low conversion photolysis. The photocycloaddn. of 1-NpCN with DMB is retarded by increasing amts. of trifluoroacetic acid which is shown to form non-photoreactive complexes with ground state as well as with singlet excited state 1-NpCN. It also quenches the *(1-NpCN-DMB) exciplex.
