Naphthalene based superplasticizer (SNF) is produced from naphthalene by oleum or sulfur trioxide sulfonation of β sulfonate. Subsequent reaction with formaldehyde leads to polymerization and the sulfonic acid  as shown in Figure 1. It is then neutralized with a suitable alkali and filtration to eliminate calcium sulfate .
