  • Preparation of Platinum Nanoparticles in Solution of Polyvinyl Pyrrolydone (PVP) by Laser Ablation Method

    • Authors: Nguyen, The Binh; Nguyen, Dinh Thanh; Nguyen, Quang Dong; Nguyen, Thi Trinh (2014)

  • Using Nd:YAG laser we studied to produce platinum nanoparticles (PtNPs) in solution of polyvinyl pyrrolidone (C6H9NO)n (PVP) by laser ablation method. The influence of average laser power, laser irradiation time, laser wave length and concentration of PVP solution in water on morphology, size distribution of PtNPs was investigated. The mean diameter of the PtNPs in 0.01M PVP solution was of 9 nm. The results on an optimum laser ablation process for preparation of PtNPs in PVP solution were discussed in this paper.

  • The Study on synthesis and transformations of some of substituted 4-methylquinolin-2(1H)-ones

    • Authors: Le, The Duan; Nguyen, Dinh Thanh; Nguyen, Thi Thanh; Hoang, Thai Vu; ... (2017)

  • Some different substituted 4-methylquinolin-2(1H)-ones have been synthesized by closing corresponding (un)substituted acetoacetanildes in the presence of ionic liquid [Bmim]OH. Obtained quinolines were conveted to its 2-chloro derivatives by reaction with POCl3. Some compounds of substituted tetrazolo[1,5-a]quinolines were synthesized by acting these 2-chloro derivatives with sodium azide in DMF as solvent. The structures of obtained compounds have been confirmed by using spectroscopic methods (IR, NMR and MS)

  • Study on the use of commercial vegetable oils as green solvents in synthesis of 2-methyl-4(1H)-quinolin-4-ones

    • Authors: Nguyen, Dinh Thanh; Le, The Duan; Tran, Thi Thanh Van; Pham, Mai Chi; Luu, Son Quy; Pham, Thi Anh; Dang, Thi Thu Hien (2016)

  • Some substituted 2-methyl-4(1H)-quinolin-4-ones have been prepared from corresponding ethyl β-(substituted)anilinocrotonates. This research contributes to the synthetic method of quinoline-4(1H)-one ring by Conrad-Limpach method with the use of vegetable oils as high boiling-point solvents, which are friendly-environmental, and not expensive friendly-environmental. The structures of different substituted 4(1H)-quinolin-4-ones have been confirmed by using spectroscopic methods (IR, 1H and 13C NMR).
