Prediction of retention indices of N1, N1-dialkylformamidines on a non-polar column

摘要: Abstract The retention indices of 80 compounds comprising four series N 2 -substituted 1 ,N -dialkylformamidines, each containing the same set 20 variable substituents R x at imino nitrogen atom ,have been measured on a non-polar silicon gum rubber GE SE-30 column. values obtained for were corelated with those corresponding model such as primary amines NH and substituted hydrocarbons H. Further support is provided an earlier conclusion that in prediction correlation method should be used instead additivity rules. A two-parameter regression -dialkylformamidines vs . secondary (R y excellent quality can trisubstituted formamidines.
