The modification was terminated by washing out the reactants from the sorbent. The diazonium group which would not react with the bait within the modification time was deactivated by hydrolysis to the corresponding phenol. Affinity chromatography. The procedure was done according to an earlier ...
sodium metaaluminate and caustic soda as raw materials for synthesis and crystallization, and then washing, drying, molding and dehydration. Molecular sieves can be divided into several types according to the connection mode and composition of silicon (aluminum) oxygen skeleton. The common ones are ...
9 Regarding the solubility of cellulose towards alkali solution, it is worthwhile to note that the so-called soda-cellulose Q (Na-cell Q; "Q" is after "quellung"), which was found by Sobue et a!., 10 dissolves in 8% (w/v) aq. NaOH solu- tion at 6°C when the polymer ...
is a material that can be used effectively to cleanse water. it is used for surface purification, bleaching, odor elimination and the disinfection of water on a wide scale. q2 is hypochlorite hazardous? hypochlorite can be used in whitening your whites, washing up the walls and serving as a...
such as a clay type catalyst. a Sulfur compound impurities may be removed in a variety of ways, depending upon the particular type of sulfur., Mercaptans, for example, are ordinarily removed by washing with caustic soda or other known reagents. Di-sulfides may be re- a moved by treatment...
Light sensitive high molecular weight compounds containing furanacrylate groups in the molecule, which can be suitably used for the preparation of photopolymerizable compositions used in light sensiti
The separated sulfonic acid is filtered off, neutralised with a solution of caustic soda and the sodium salt evaporated to dryness. It possesses excellent capillary-active properties and can be used both as calcium soap solvent or emulsifier and also as washing agent. 88.5 parts of lauroyl-N-...

The products are of use as auxiliary agents in emulsifying, dispersing, softening, washing and wetting processes, and their capillary activity is enhanced by the subsequent alkylation and/or sulphonation. In examples: (1) m -methylbenzimidazole is condensed with lauryl chloride (or cetyl-, stearyl...
