The synthesis of 1,4dioxane employing the diethylene glycol as raw material and sodium bisulfate monohydrate as catalyst was discussed.

To evaluate the antioxygenic property of the antioxidants, the oxidation reaction rate constants of sodium sulfite, sodium bisulfite and sodium pyrosulfite in aqueous solutions were determined.

Nonylphenol polyoxyethylene ether was esterified with maleic anhydride and then sulfonated with sodium bisulfite to form nonylphenol polyoxyethylene ether sulfosuccinic acid diester sodium salt.
