Displacement Chromatography on Synthetic Ion - exchange Resins
In Part 1 of this series of papers (Partridge & Westall, 1949) it was shown that, whilst the baseexchange resin Zeo Karb 215 may be used with success for the separation of the neutral and acidic amino-acids, certain difficulties arise when the separation of basic substances is attempted. These difficulties were traced to the phenolic hydroxyl groups of the resin. Resins of the sulphonated pheno...

15 صفحه اولSealing with Carbotech Fosroc Synthetic Resins
A survey is given on the various options to seal water ingress from strata and from concrete structures by injecting different types of resins showing the scope and limits of the individual grouts. The report covers methacrylates and polyurethane hydrogels, one and two component polyurethane resins as well as silicate isocyanate resins. The use of fast reacting two component polyurethane resins...
متن کاملSoftening Point Experiments Compare Methods’ Ease, Accuracy
Softening and dropping point determination are established analytical tests that provide quality control for petrochemical products such as bitumen (asphalt). However, to be accurate, manual/semi-automated quality tests prescribed in ASTM standards must be performed in a standardized fashion. Unfortunately, manual processing bears inherent process risks that affect repeatability, which in turn ...
متن کاملSolving time-fractional chemical engineering equations by modified variational iteration method as fixed point iteration method
The variational iteration method(VIM) was extended to find approximate solutions of fractional chemical engineering equations. The Lagrange multipliers of the VIM were not identified explicitly. In this paper we improve the VIM by using concept of fixed point iteration method. Then this method was implemented for solving system of the time fractional chemical engineering equations. The ob...
