Continuous Synthesis of Oleyl Oleate in Supercritical Carbon Dioxide using Solid p-Toluenesulfonic Acid as Catalyst
Supercritical carbon dioxide (SC-CO2) was used as solvent to synthesize oleyl oleate as an analog of Jojoba oil from oleic acid and oleyl alcohol with high conversion (100%) of the acid into ester in a short time of 100 min. Utilizing a low cost solid catalyst, p-toluenesulfonic acid monohydrate (PTSA), the esterification reaction was performed, without any prior preparation step...

A novel carbon-based solid-acid catalyst was simply prepared for the first time by the thermal treatment of p-toluenesulfonic acid (TsOH) with D-glucose at 180 C in a sealed autoclave and it was proved to ha...
متن کاملHydrolysis of Proteins with p-Toluenesulfonic Acid
A new procedure for analyses for tryptophan in proteins and glycoproteins is described. The method utilizes ptoluenesulfonic acid as the catalyst for hydrolysis and the amino acid analyzer for the quantitative estimation of tryptophan. The hydrolysis of proteins is carried out in 3 N p-toluenesulfonic acid containing 0.2 % 3-(Z-aminoethyl)indole in evacuated sealed tubes at 110” for 22, 48, and...
متن کاملSynthesis and optimization ring opening of monoepoxide linoleic acid using p-toluenesulfonic acid
Biolubricant base oils, 9,12-hydroxy-10,13-oleioxy-12-octadecanoic acid (HYOOA) was synthesized based on the esterification reaction of Monoepoxide linoleic acid 9(12)-10(13)-monoepoxy 12(9)-octadecanoic acid (MEOA) with oleic acid (OA) and catalyzed by p-Toluenesulfonic acid. The optimum conditions for the experiment using D-optimal design to obtain high yield% of 84.61, conversion% of 83.54 a...
