Effects of ionized cyclodextrin on decomposition of allyl isothiocyanate in alkaline solutions.
The secondary hydroxyl ion (alkoxide) ion for cyclodextrin (CD) may affect the decomposition of allyl isothiocyanate (AITC) in alkaline solutions. The equilibrium and kinetic parameters involved in the reaction processes were measured. It was found that the interaction between the alkoxide ion for CD and the included AITC occurred more than pKa 12.7. From the identified kinetic parameters and d...
متن کاملThe Alkaline Decomposition of Serine
A method for the quantitative estimation of arginine is included by Van Slyke (1911-12) in his procedure for the determination of the nitrogen distribution numbers of proteins. The amino acids present in the protein hydrolysate are divided into two groups by means of phosphotungstic acid. The portion precipitated by t,his reagent is referred to as the basic or diamino fraction and the portion n...
متن کاملDecomposition of a Di Azo Dye in aqueous solutions by
This study examined the photolytic degradation of C.I. Acid Red 73 AR73 diazo dye, in aqueous solution by combined UV, hydrogen peroxide and KMnO4. A continuous circulated photoreactor equipped with a low pressure mercury lamp 15 W, emission 253.7 nm was used. In the first step, potassium permanganate was used for decolourisation of AR73 dye solution. The effect of the key operating variables s...
متن کاملDeprotonation of beta-cyclodextrin in alkaline solutions.
Variable pH (13)C NMR and (1)H NMR spectroscopic studies of the beta-cyclodextrin (beta-CD) in alkaline aqueous solutions revealed that beta-CD does not deprotonate at pH<12.0. Further increase in solution pH results in the deprotonation of OH-groups adjacent to C-2 and C-3 carbon atoms of beta-CD glucopyranose units, whereas the deprotonation of OH-groups adjacent to C-6 carbon atoms is expres...
متن کاملAnesthesia in Acid and Alkaline Solutions
The action of distilled water in producing anesthesia (loss of response to electrical stimulation) in Nitella is hastened by the addition of acid and alkali and retarded by the addition of calcium. The loss of irritability is fully reversible.
