Water → 1,2-bis(N-(2-hydroxyethyl)-lauroylamino)ethane

Participants

Reaction Steps

Into a 500 ml rounded-flask, were introduced 4.0 g of magnesium oxide and 80 g of distilled water. The mixture was stirred. Thereto was added 7.3 g of N,N'-bis(2-hydroxyethyl)-1,2-diaminoethane prepared in Example 27, and then was added 250 ml of 1,4-dioxane. 21.3 g of lauroyl chloride was gradually added dropwise to the resulting mixture for 1 hour under violent stirring at a room temperature. After stirring for 2 hours, the mixture was filtered, and the filtrate was mixed with 200 ml of chloroform, and washed twice with 200 ml of distilled water. The organic phase was cooled to produce solid material, which was recovered by filtration. The solid material was dried and recrystallized from acetone, to give 19.5 g of the title compound as white powder, which was identified by IR and NMR. The results are shown in Table 3.
