EOR surfactant preparation

Because EOR surfactant and additives are anionic sulfonate and Food dehydrator, its enhanced oil recovery is most significant, so here focuses on EOR important anionic sulfonate and carboxylate synthesis and preparation. Sulfonation of the salt used in preparation of the sulfonating agent, concentrated sulfuric acid are used? oil expeller Trioxide and chlorosulfonic acid. For large-scale industrial production, comprehensive comparisons to sulfur trioxide sulfonation process optimization, its versatility? Security? Applicability are better and lower cost. So sulfonate synthesis industry gained wide application and development.
