solubility of the salts was determined. The experimentalprocedure adopted was as follows.
The saturated urea, thiourea and solutions of A to C (solution A, B and C = 0.1, 0.25 and 0.5, UTMC in water) are prepared individually. Then the empty weight
+ 5-Bromoindole and 2,3-Dimethylindole + 5-Fluoroindole in benzene in the said temperature range. The result obtained are presented here and discussed.

supplementary characterization of winterized fractions.
The Babassu biodiesel was obtained by transesterification reaction through the ethanol route. The physical chemistry parameters of the biodiesel were in
the oil degradation as a function of temperature.
The synthesis of the Beta zeolite was carried out hydrothermally starting from the experimentalprocedure described earlier [ 17 – 19 ], from the system
composite hybrid AlMCM-41/ZSM-5 was synthesized by the hydrothermal method, based on an adapted experimentalprocedure [ 8 ], and molar composition SiO 2 :0.32Na 2 O:0.03Al 2 O 3 :0.20TPABr:0.16CTMABr:55H 2 O. Aqueous solutions of tetrapropylammonium bromide
investigated. Further, we study the effect of various heat treatment schedules on the thermo-physical properties of the glass ceramics and optimize process parameters for an application like glass-ceramic-to-metal (GCM) seals.
