标 题:Synthesis of linear phosphorus-containing functional fluorocopolymer
发明人：WANG LIANG; WANG VIKTORIA
权利人:WANG LIANG; WANG VIKTORIA
摘要:This invention relates to a synthesis of a linear fluorocopolymer having a plurality of pendant phosphorus-containing functional groups. The synthesized phosphorus-containing fluorocopolymer has chain linearity and narrow molecular weight distributions. It has applications as a lubricant additive that provides friction-reduction, anti-wear, and corrosion protection properties.

标题:Synthesis method of indole derivative capable of efficiently degrading perfluorinated compound (PFC)

摘要:A synthesis method of an indole derivative capable of efficiently degrading a perfluorinated compound (PFC) and a use of the indole derivative are provided. The synthesis method includes dissolving an appropriate amount of indole, alkylamine, and formaldehyde in an ethanol solution, conducting a reaction at reflux under suitable conditions for a specified period of time with ZnCl 2 or glacial acetic acid as a catalyst to form a reaction product, vacuum-drying the reaction product, and purifying the reaction product through column chromatography to obtain a novel indole derivative with a hydrophobic alkyl branch. The present indole derivative has some hydrophobicity and a positively charged amino group that can effectively capture PFCs in contaminated water to produce a sub-nanoscale self-assembled aggregate. Hydrated electrons generated by light irradiation can directly attack PFCs in the aggregate without long-distance mass transfer, improving the utilization rate of hydrated electrons and reduces the ratio of fed materials.

标 题:Synthesis of porous carbon-based materials from expanded polystyrene
发明人：SAHA DIPENDU; GRAPPE HIPPOLYTE A
权利人:Eco Carbon LLC
摘要:A process for synthesizing a carbon molecular sieve and an activated carbon from expanded polystyrene is provided. The process includes sulfonating the expanded polystyrene with sulfuric acid in the presence of a solvent, for example, chloroform, to obtain sulfonated polystyrene; carbonizing the sulfonated polystyrene to obtain a carbon molecular sieve (CMS) with a substantially high degree of porosity; and activating the CMS by adding an activating agent to the CMS to obtain an activated carbon with a substantially high degree of porosity. The activating agent is selected from one or more of steam, potassium hydroxide, carbon dioxide, zinc chloride, phosphoric acid, sodium carbonate, aluminum chloride, magnesium chloride, and sodium hydroxide. A low temperature of, for example, about 50 degrees Celsius, is employed for sulfonating the expanded polystyrene. Heating and cooling operations in the steps of synthesizing and activating the CMS are performed under a nitrogen gas atmosphere.
