Abstract: A method for increasing moisture retention in a soil includes applying an effective amount of an effective humectant composition to the soil. The effective humectant composition is identified by determining the average moisture content of the soil for the humectant compositions applied at a minimum humectant concentration level, a maximum humectant concentration level, and at a first concentration level between the minimum and the maximum humectant concentration level. An average slope curve is generated by plotting the determined average moisture content of the soil for each applied humectant concentration levels from the minimum humectant concentration level to the maximum humectant concentration level. An effective humectant composition is determined when the generated average slope curve provides an increasing average moisture content along the entirety of a length of the generated average slope curve and when the generated average slope curve has a p value of 0.05 or less.

Abstract: The present invention relates to a process for hydrogenating a mixture (G1) in the presence of a catalyst, where the mixture (G1) comprises at least one colorless amine and at least one color-imparting component. As a result of the hydrogenation step, the at least one color-imparting component is firstly partially, preferably fully, hydrogenated, while the colorless amine, in particular aniline, is not hydrogenated or hydrogenated to only a very small extent. The color-imparting components which cause the discoloration of the amine which is itself in principle colorless are thus removed by hydrogenation, as a result of which purification of the colorless amine or the mixture (G1) is achieved.
