The maleic acid-castor oil monoester (MACO) was synthesized and was used as monomer to synthesize a new potentially environmentally friendly copolymer of styrene and MACO (poly-St/MACO) by suspension polymerization. Under the appropriate conditions, the poly-St/MACO with yield of 81%, number average molecular weight of 44100g/mol, and molecular weight distribution of 1.5 could be obtained. The chemical structures of the MACO and resulting copolymer were confirmed by Mass Spectrometry Infrared Spectroscopy and Nuclear Magnetic Resonance Spectroscopy H[1]. The results of thermogravimetric analysis and biodegradation test showed the poly-St/MACO can be used as a new potentially environmentally friendly material with excellent thermal stability. © 2011 John Wiley & Sons, Ltd.

This article covers a method for synthesizing environmentally friendly multifunctional metal (calcium, magnesium) oléate detergents with antioxidation property. These multifunctional metal (calcium, magnesium) oléate detergents with antioxidation property were synthesized using oil-soluble liquid antioxidants (PPIBP, PPIBTSTBP, and PPIBPDA) as reactive functional materials. These oil-soluble liquid antioxidants have the potential to be used as functional materials for application in synthesizing other kinds of substrate detergents. Source

In order to improve the utilization efficiency of carbon dioxide and calculate the amount of carbon dioxide better, a series of magnesium salt detergents (including magnesium oleate, magnesium linoleate, magnesium isostearate and magnesium sulfonate) was synthesized using a novel method of quantitative carbon dioxide, and this method has the potential for synthesizing more organic acid magnesium salt detergents. © 2011 American Chemical Society.

Silicon monoxide/graphite/multi-walled carbon nanotubes (SiO/G/CNTs) material was prepared by ball milling followed by chemical vapor deposition method and characterized by X-ray diffraction, scanning electron microscopy (SEM), galvanostatic charge-discharge, and AC impedance spectroscopy, respectively. The results revealed that SiO/G/CNTs exhibited an initial specific discharge capacity of 790 mAh g -1 with a columbic efficiency of 65%. After 100 cycles, a high reversible capacity of 495 mAh g -1 is still retained. The improved electrochemical properties were due to beneficial SEI by the SEM and EIS results. © 2011 Springer-Verlag.

The catalytic activity of KF/MgO for the synthesis of didodecyl carbonate (DDC) by transesterification of dimethyl carbonate (DMC) with dodecanol (DoOH) was studied. The effects of KF loading and calcination temperature were investigated. The catalysts were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and N2 adsorption-desorption. The results indicated that new phases K2MgF4 and K2CO3 were formed when KF/MgO was calcined in air at high temperature. K2MgF4 and K2CO3 were the main catalytic sites in this reaction. KF/MgO was an effective catalyst in this transesterification reaction and the optimized KF loading and calcination temperature were 30% and 873 K, respectively. The optimized reaction conditions were as follows: n(DoOH):n(DMC)=4, catalyst amount 0.75%, reaction time 4 h. Under these conditions, the conversion of DMC and the yield of DDC were 86.7% and 86.2%, respectively. Source
