The Ionization of Protein Chlorides
1. By the use of the silver-silver chloride electrode, measurements have been made of the chloride ion concentrations of 1 per cent solutions of five proteins, containing from 0.001 N to 0.1 N hydrochloric acid. The hydrogen ion concentrations of the same solutions have been measured by the use of the hydrogen electrode. 2. The measurements indicate that the chlorides of gelatin, egg albumin, c...
متن کاملUnexpected stable stoichiometries of sodium chlorides.
Sodium chloride (NaCl), or rocksalt, is well characterized at ambient pressure. As a result of the large electronegativity difference between Na and Cl atoms, it has highly ionic chemical bonding (with 1:1 stoichiometry dictated by charge balance) and B1-type crystal structure. By combining theoretical predictions and diamond anvil cell experiments, we found that new materials with different st...
متن کاملCopper-catalyzed nucleophilic trifluoromethylation of benzylic chlorides.
Reactions of primary and secondary benzylic chlorides with trifluoromethyltrimethylsilane in the presence of a catalytic amount of copper(i) thiophene-2-carboxylate (CuTC) have been found to give the corresponding benzylic trifluoromethylated products in good to high yields.
متن کاملCatalytic SNAr of unactivated aryl chlorides.
We present nucleophilic aromatic substitution of unsubstituted aryl chlorides via a mechanism that is catalytic in [CpRu(p-cymene)]PF6 and involves a Ru(η(6)-arylchloride) intermediate. From the spectroscopic evidence we infer that arene exchange is the rate limiting step in this process and develop several new Ru(ii) complexes that lower the activation barrier to arene exchange.
متن کاملThermodynamic Characteristics of Samarium and Europium Chlorides in Molten Alkali Metal Chlorides
The formal standard redox potentials of samarium (III)/(II) (EZmi+/ Smi+) and europium (III)/(II) (•£,£u3+/eu2+ ) *n molten alkali metal chlorides were measured potentiometrically against a reference chlorine electrode. The Gibbs energy changes and equilibrium constants for the reaction LnCl2(D + V2 Cl2(g) LnCl3(I) were calculated for the salt systems studied. The effect of the cationic composi...
