Chromatographic Separation and Identification of Nylon-9 Intermediates and Coproducts Derived from Soybean DiP
نویسندگان
چکیده
9-Aminononanoic acid, 9-aminononanamide, and related compounds derived from soybean oil by reactions, including reductive ozonolysis and reductive amination, were separated on an analytical scale either by gas liquid chromatography of trifluoroacetylated or trimethylsilylated derivatives or by thin layer chromatography and on a preparative scale by ion-exchange chromatography. Comparative analyses also were carried out with certain homologous wamino acids and amines.

Xenon and krypton separation in a chromatographic column packed with granulated nano NaY zeolite
In order to investigate the gas separation ability of a column packed with nanozeolitic material, nano NaY zeolite was synthesized and granulated. These uniform granules packed in a chromatographic column were utilized for separation of Xe and Kr under various operating conditions. With regards to the response peaks obtained from trace injections of Xe and Kr into the column, the first and seco...
متن کاملDesign and Fabrication of an Improved Single-Column Chromatographic Separation Process
In this work, an improved single-column chromatographic (ISCC) separation process is proposed. The term `improved' refers to both conceptual and physical modifications compared to the available single-column processes, including a novel fraction collection scheme and allowing overlapped peaks from adjacent cycles. Also the fraction collection mechanism was modified in order to facilitate online...

متن کاملPhysical separation of amphiprotic-polar aprotic solvents for simultaneous extraction and clean-up of clomiphene from plasma before liquid chromatographic analyzes
An efficient and quantitative two phase freezing (TPF) method coupled with high performance liquid chromatography and UV-Vis detector was developed for the extraction, clean up and determination of clomiphene citrate (CLC) in plasma samples. The separation of two miscible solvents by TPF method permits that the CLC was efficiently removed from proteins and transferred into the relative aprotic ...
