(3). (3)IV=mlNa2S2O3black−mlNa2S2O3sample×N×12.69sample oil(g)Where; N is normality of sodium thiosulfate (Na2S2O3) expressed as equivalent l−1 and 12.69 is a constant related to the equivalent weight of iodine. The SV of J. curcas oil was determined by saponifying the oil ...
The compounds of formula (I) wherein X is a carboxylic acid and in the form of a diglyceride can be prepared by reaction of the fatty acid (2 equivalents) with glycerol (1 equivalent) in the presence of 1,3-dicyclohexylcarbondiimide (DCC) and 4-dimethylaminopyridine (DMAP). The compounds...
This allows the use of an excess solution of the leaching agent—ammonium bisulfate, but at the same time, do not consume superequivalent amounts of ammonia at the stage of cleaning the solution from iron, which is returned to the head of the process. The actual process is more complex, ...
of 1 was used as the glycosyl acceptor, the desired GalNAc-GM1b framework (33) was obtained in 31% yield. Increasing the equivalent amount of the acceptor increased the coupling yield to 60%. Finally, global deprotection to remove the acetyl, benzoyl, and succinyl groups was performed by ...
