Abstract—A study about variation of calcium metal concentration in mixed Ca/Mg/Zn metal to produce of soap with high alkaline content together with oleic acid was studied. Calcium metal which is used vary from 15 (15μ), 50 (50μ) and 85 (85μ) % with modified fusion as method for saponification. Variation of calcium metal into mixture of Ca/Mg/Zn metal is proved to have different effect to alkaline content value and oleic acid conversion into basic soap. Soap from variation of 85μ had alkaline content of 44.5% weight. Inside the whole soap produced from 15μ, 50μ and 85μ, hydroxyl group was detected with low intensity inside the range of wavenumber length of 3200-3570 cm-1 according to FT-IR spectrum. Maximum conversion of oleic acid into soap happened when varied at 50μ is 97.9%.

Index Terms—Metal mixing, alkaline content, soap, hydroxyl group.
