Von Braun (BrCN) Reaction on Solasodine
von Braun Cyanogen Bromide Reaction, Solasodine, 13C NMR Solasodine on reaction with BrCN yielded two isomeric cyanamides in a ratio of 3:1, which have been characterised as C-22 configurational isomers, N-cyanosolasodine (22 R, 25 R) I IA and N-cyanosolasodine (22 S, 25 Rj II B on the basis of HI and *3C NMR studies. The same reaction with piperidine, yielded its cyanamide, the 13C NMR of whic...
متن کاملSome Extensions of von Braun (BrCN) Reaction on Organic Bases
von Braun Cyanogen Bromide Reaction Some extensions of von Braun cyanogen bromide reaction have been undertaken on conessine, isoconessine and two simpler bases, dimethyl a-naphthyl amine and diethyl amine. The monocyanamides of conessine and isoconessine yielded acid amides, aminoderivatives (diamines) and guanido derivatives on careful hydrolysis, reduction and treatment with ammonia, respect...
متن کاملAutomated microdetermination of inorganic phosphorus in serum and urine by the ammonium molybdovanadate method.
Continuous flow assay of inorganic phosphorus in 20 ¡A serum or urine is described. The procedure is based on the formation of a colored complex of inorganic phosphorus with ammonium molybdovanadate and does not require the presence of a reducing agent, thus producing an extremely stable baseline. The reaction product is measured at 340 nm for serum samples but at 420 nm for urine samples, sinc...
متن کاملhydrochlorothiazide detection in urine samples by hplc-dad and experimental design dispersive l-l microextraction
hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...
suppression of coke formation in thermal cracking by coke inhibitors
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
