Preparation of surfactants by sulfonating derivatives of depolymerized coal |
| abstract |
Surfactants or surface active agents may be obtained by treating the product obtained from the boron trifluoride etherate catalyzed depolymerization of coal with a sulfonating agent such as sulfur trioxide and thereafter neutralizing the sulfonated product with a basic compound such as sodium hydroxide to obtain a sodium sulfonated derivative of the depolymerized coal product. |
