Three activated carbons having different surface areas, coconut-shell based, pelletized and bamboo-derived, were modified by mixing them with four thermoplastic precursors, poly, hydroxy propyl cellulose, citric acid, and fluorine-containing polyimide followed by heat treatment at 900℃ for 1h.

三种具有不同比表面积的活性炭—椰壳基AC-C、粒状AC-P和竹基AC-B分别与四种热塑性前驱体—聚乙烯醇,羟基丙基纤维素,柠檬酸,含氟聚酰亚氨混合后,在900℃热处理1h。

The recent progresses in these fields were summarized in this paper. It focuses on the activation and oxidation on a series of hydrocarbons (from CH4 to these hydrocarbons with six carbons). The catalysts and oxidants reported here include organic metal compounds and inorganic compounds (such as molecular sieves, metal clusters, metal oxidates and so on).

本文总结了近几年在碳氢化合物的活化及氧化领域的一些新进展,涉及的底物包括从甲烷到碳原子数等于6的烃类,而催化剂及氧化剂包括有机金属化合物和无机化合物(如分子筛催化剂、金属团簇和金属氧化物等)。

VLE data at different pressures of alcohols– nitriles (the number of the carbons is below 5) binary systems were calculated by Wilson equations.

在上述基础上,利用Wilson模型对5个碳以下的醇类和腈类组成的33种二元物系进行汽液平衡(来源:ABC56论文网www.abclunwen.com)数据的推算。

At first, the broth was acidified, then centrifuged to get mycelia, which was heated and powdered; finally we use acetic ether to soak the powder. After that, the phase of acetic ether was washed using the solution of ammonium sulfate and the solution of ethanedioic acid, then concentrated to gain pulps. It was crystallized at 4℃.The coarse crystals was decolorized by activated carbons, the pure needle crystal of lovastatin was obtained.

发酵液经酸化处理后,离心得到菌体,烘干后过筛得到菌粉;用乙酸乙酯浸泡,乙酸乙酯相需用(NH_4)_2SO_4溶液和草酸溶液洗涤两次;乙酸乙酯相经薄膜浓缩得到浆状物,于4℃结晶,得到粗晶体;再经粉末活性炭脱色和重结晶后得白色针状结晶,为lovastatin的纯品。

For the chemical shifts of the carbons that lay in the conjugated sketeton we obtained a good linear relationship between the calculated and experimental data as well as their antimagnetic contribution σ_d and electronic density ρ.

对于固定在π骨架上的碳原子,其化学位移计算值与实验结果有很好的线性关系,并且它们的反磁性贡献σ_d和电荷密度ρ之间也有较好的线性关系。
