A series of 1-(2-methoxyphenyl)-3-pivaloylthiourea, substituted guanidines were synthesized in good yield by condensation reaction of 1-(2-methoxyphenyl)-3-pivaloylthiourea with different aliphatic amines by using HgCl2 as guanilating agent.A series of 1-(2-methoxyphenyl)-3-pivaloylthiourea, substituted guanidines were synthesized in good yield by condensation reaction of 1-(2-methoxyphenyl)-3-pivaloylthiourea with different aliphatic amines by using HgCl2 as guanilating agent.

Biodiesel was synthesized from vegetable oils by base-catalyzed transesterification with methanol in the presence of NaOH. The optimization of experimental parameters was established to achieve the maximum yield of product. The physical and fuel properties of biodiesel like dynamic viscosity, kinematic viscosity, acid number, density, flash point, cetane number, cloud point and pour point were determined and found comparable to ASTM standards. Prepared biodiesel was chemically characterized by FT-IR, NMR (1H & 13C) and GC-MS to elucidate the identification, quantification and chemical...
