Superiority:
Ethoxylated fatty alcohols are often converted to the organosulfate. The conversion typically uses sulfur trioxide or chlorosulfuric acid:
- R(OC2H4)nOH + SO3 → R(OC2H4)nOSO3H
- R(OC2H4)nOH + HSO3Cl → R(OC2H4)nOSO3H + HCl
The resulting sulfate esters are neutralized to give the salt:
- R(OC2H4)nOSO3H + NaOH → R(OC2H4)nOSO3Na + H2O
Small volumes are neutralized with alkanolamines such as triethanolamine (TEA).[4] In 2006, 382,500 metric tons of alcohol ethoxysulfates (AES) were consumed in North
