The role of solvent in chemical reactions - Part I. The reaction between pyridine and methyl iodide
V S Padmanabhan S V Anantakrishnan
The reaction between pyridine and methyl iodide has been studied in 95 per cent. ethyl alcohol and in acetone. The reaction is faster in the latter solvent at the three temperatures studied. The Arrhenius parameters have been evaluated and the variations discussed in relation to solvent influences.

The role of solvent in chemical reactions - Part II. The reaction between aniline and methyl iodide in different solvents
The reaction between aniline and methyl iodide has been studied at four different temperatures in 95% ethyl alcohol, acetone, nitrobenzene and carbon tetrachloride. The complications arising from progressive alkylations as well as from the crystallisation have been minimised under the experimental conditions in the initial stages. The observed changes in the rate constants and in the Arrhenius parameters are discussed.
