| Abstract: | Betaines, RN Me2CH2COO with R=lauryl palmityl and steeryl, are prepared from alkyldimethylamines and CICHCOOH. The yield of betaines can be raised by using NaHCO3 as a base and the reaction time can be reduced by adding a small amount of betaine.Some surface activities of betaines with different alkyl are measured and compared. |
