Investigation of lactams
The recen t ly developed methods of synthesizing substi tuted 1H,2,3 ,4te t rahydroazepino[3,4-b] indoles [1-3] f rom cap ro l ac t am have opened broad pe r spec t ives for p repar ing condensed lndole de r iva t ives of biological in te res t [4]. In pa r t i cu la r , it became of in te res t to synthesize the indole analogs of such biological ly active compounds as Corazol ( a f t p e n t a m e t h y l e n e t e t r a z o l e ) [5], Omethy lcapro lac t im [6], and also a s e r i e s of 1,2and 10-subst i tu ted azepino[3,4b]indoles for pharmacologica l investigation.
Formamid-Reaktionen, XIV. Reaktionen von Säureamid-Acylhalogenid-Addukten: Darstellung substituierter Amidine und Amidrazone
Die Struktur des kristallin erhaltenen Dimethylformamid-Phosphoroxychlorid-Adduktes wird erortert. N.N-Disubstituierte Amide geben mit Phosphoroxychlorid und Aminen N.N.N′-trisubstituierte Amidine. Die Umsetzung des Dimethylformamid-Phosphoroxychlorid-Adduktes mit Hydrazinen fuhrt zu den bisher unbekannten Formyl-formamidrazonen. Durch Umsetzung von Formaniliden mit Alkylierungsmitteln entstehen N.N′-disubstituierte Formamidine.
The Determination of Physicochemical Characteristics of Biodiesel and Its Blending Oils
The viscosity,combustion heat,sulfur content,carbon residue,ash,flash point,moisture and cetane value of biodiesel and its blending oils with diesel were determined.The influence of temperature on the viscosity was studied,and the physicochemical characteristics of biodiesel and its blending oils were compared with diesel.The results indicated that biodiesel and its blending oils had some superior performances and good application prospect.
