This report presents the economics of Linear Alkylbenzene Sulfonate (LAS) production from linear alkylbenzene (LAB) and oleum (10-25% sulfur trioxide in sulfuric acid) in the United States, via a conventional sulfonation process. Sulfur trioxide is the sulfonating agent and the primary product is the para-alkylbenzene sulfonic acid, which is further neutralized.
This report analyses the economics of Linear Alkylbenzene Sulfonate (LAS) production from linear alkylbenzene (LAB) and sulfur in the United States, via a conventional sulfonation process. In this process, elemental sulfur is burned, yielding sulfur dioxide, which is then oxidated with dry air to produce sulfur trioxide, the sulfonating agent. The primary product is the para-alkylbenzene sulfonic acid, which is further neutralized.
