The propyl-phenyl-ether derivative produced as described above can be purified by means such as column chromatography using silica gel, column chromatography using an ion exchange resin or the like, treatment with activated carbon, extraction, distillation, crystallization or the like. In the cosmetic...
Our results show that the CR-I (+)-column can be applied for the separation of endogenous DAACPs generated by the post-translational modification.Biochimica et Biophysica Acta (BBA) - Proteins and Proteomicsdoi:10.1016/j.bbapap.2020.140429Izuru Kawamura a b...
(150 mL×3). The combined organic layers were partitioned with brine, dried over MgSO4, filtered and concentrated under reduced pressure. The resultant oil was purified by silica gel column chromatography; the product eluted with dichloromethane/hexane (2:3), to afford the desired product as a...
In this paper, the sample is treated with p-toluenesulfonic acid-acetic anhydride as the cracking agent, and SE-30 capillary chromatographic column is employed to measure the initiator of polyether and polyoxyethylene alkyl ether and the mass ratio between ethylene oxide and propylene oxide at the ...
Column- and gel-chromatography have been used to study the phenylglycidyl ether (PGE) oligomers produced in the presence of dimethylbenzylamine with or without alcohol as additive. The oligomers have been found to possess a trimodal terminal OH-group distribution and to contain also non-hydroxyl ...
Column liquid chromatographyEnantiomeric separationChiral stationary phaseCyclodextrinDinitrophenyl etherThe comparisons of five different chiral stationary phases (CSPs) based on 2,6-dinitro-4-trifluoromethylphenyl (DNP-TFM) ether substituted β-cyclodextrin are presented. The five CSPs differ from each ...
The relative proportion of rearrangement products is dependent on the temperature of the capillary column and the substituents on the phenyl ring.J. ZhaiW. YingFz ZhaoYz Chen中国化学快报(英文版)J.J.ZHAI. Detection of claisen rearrangement occurring in allyl phenyl ether by in situ GC/MS[J]....
The use of a reversed‐phase C18 column (250mm×4.0mm and 5m) using a gradient elution system enabled six compounds to be separated simultaneously in a single chromatographic run in less than 12 minutes. The method was successfully validated following ICH guidelines, and it has been demonstrated...
Non-linear plots of the logarithms of capacity factors versus the number of oxyethylene units in sulphated oligomers were observed on the bonded amino column in mobile phases consisting of cetyltrimethylammonium bromide, 2-propanol and n -heptane. It is possible to separate sulphated oligomers and...
