【Abstract】 The process of the synthesis of sodium dodecylbenzene sulfonate is studied in detail in this paper.The synthesis reaction proceeds in a trough reactor and dodecylbenzene is used as a raw stuff,sulfur trioxide as the sulfonating agent,sodium hydrate as the neutraliz- ing agent.The present authors discussed the effects of sulfonating temperature and charge ratio on the quality of the product and determined the best technological paramethers, which involve sulfonating temperature,ratio of crude materials,etc.,of preparing sodi- um dodecylbenzene sulfonate with high purity and high solid content.更多还原
