Pandect of sulfate surfactants (2): Production method

1 Alkyl sulfates
Alkyl sulfates are synthesized with fatty alcohols and sulfur trioxide as raw materials via continuous reactor (eg: film reactor); the production method is currently the most widely used.
Primary alcohols are mainly used for preparation of linear alkyl sulfates; secondary alcohols are mainly used for preparation of secondary alkyl sulfates
The reaction procedure is as follows:
Finished product status of alkyl sulfates may be liquid, or powder, or needle-like solid.
Furthermore, secondary alkyl sulfates are synthesized with olefins and sulfuric acid as raw materials; the products are also known as Teepole.
The reaction procedure is as follows:
