4-Sustituted derivatives of Hantzsch 1,4-dihydropyridine were oxidized by nitric oxide donor isoamyl nitrite in CH3CN at room temperature to give the corresponding pyridine derivatives.When 4-substituted group was met...
With activated carbon supported tungstosilicic acid as catalyst,isoamyl propionate is synthesized directly under normal pressure and microwave irradiation.The configuration of samples is characterized by IR and NMR.Th...
Solid acid ferric sulphate Fe2(SO4)3 was prepared and used for the study of the catalytic synthesis of iso-amyl propionate.The optimun reaction conditions were follows:the ratio of amount of substance n(iso-amylalc...
Synthetic method of solid superacid TiSiW 12 O 40 /TiO 2 was described.The synthesis of iso amyl propionate catalyzed by TiSiW 12 O 40 /TiO 2 has been studied and the factors influencing on the yield is discussed.It s...
Isoamyl isovalerate has been synthesized by using solid superacid SO 2- 4/TiO 2 as catalyst.The effect of catalyst,activation temperature,ratio of acid to alcohol,reaction time to the productivity of ester was studied...
The synthesis of isoamyl hexanoate with isoamyl alcohol and hexanic acid as reactants and sodium bisulfate as catalyst had been studied.The factors affecting reaction were investigated.The results showed that the appr...
In this paper a new solid superacid catalyst SO 2- 4 MoO 3 TiO 2 was prepared.The activity of the catalyst in esterification of acetic acid and iso amyl alcohol was measured and compared with that of SO 2- 4 TiO 2 and...
