Synthesis of environmentally friendly calcium oleate detergent / Yonglei Wang ; Wumanjiang Eli ; Yuanfeng Liu in Industrial & engineering chemistry research, Vol. 47 n°22 (Novembre 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 n°22 (Novembre 2008) . - p. 8561–8565 Titre : Synthesis of environmentally friendly calcium oleate detergent Type de document : texte imprimé Auteurs : Yonglei Wang, Auteur ; Wumanjiang Eli, Auteur ; Yuanfeng Liu, Auteur Année de publication : 2008 Article en page(s) : p. 8561–8565 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : calcium  oleate  Ca(OH)2  detergent Résumé : This article discusses a method for synthesizing an environmentally friendly calcium oleate detergent using vegetable oil instead of mineral oil as the raw material. Reaction conditions including the molar ratio of total lime [Ca(OH)2 and CaO] to oleic acid, the molar ratio of Ca(OH)2 to CaO, the carbonation temperature, the amount of methanol, the molar ratio of water to CaO, the gas flow rate of CO2, and the molar ratio of injected CO2 to total lime [Ca(OH)2 and CaO] were optimized. Using the optimized conditions, a high-alkali calcium oleate solution with a total base number (TBN) of 376 mg of KOH/g and an overbased calcium oleate solution with a value of TBN = 420 mg of KOH/g could be obtained.
