After this, 5 mL samples of the saturated solution were taken by pipette, diluted to 25 mL with nitromethane and titrated against 0.07 N tetrabutylammonium hydroxide solution.", "reference": {"citation": "Timmermans, J.; Physico-Chemical Constants of Pure Organic Compounds (Elsevier, New York, 1950).", "pubtype": "book"}, "dataset": [{"series": 1, "title": "Solubility of propanedioic acid in nitromethane", "points": [{"pntnum": 1, "conditions": [{"property": "Ambient temperature", "number": "0e+00", "significand": "0", "exponent": "0", "sigfigs": "0", "unit": "&deg;C"}, {"property": "Ambient temperature", "number": "2.732e+02", "significand": "2.732", "exponent": "2", "sigfigs": "4", "unit": "K"}], "data": [{"property": "Amount Concentration (1)", "number": "1.2e-02", "significand": "1.2", "exponent": "-2", "sigfigs": "2", "unit": "g/L"}], "supplemental": [{"property": "Percent mass fraction (2)", "number": "1.1e-03", "significand": "1.1", "exponent": "-3", "sigfigs": "2", "unit": "1"}, {"property": "Mole fraction - Liquid (2)", "number": "6e-04", "significand": "6", "exponent": "-4", "sigfigs": "1", "unit": "1"}]}, {"pntnum": 2, "conditions": [{"property": "Ambient temperature", "number": "1.50e+01", "significand": "1.50", "exponent": "1", "sigfigs": "3", "unit": "&deg;C"}, {"property": "Ambient temperature", "number": "2.882e+02", "significand": "2.882", "exponent": "2", "sigfigs": "4", "unit": "K"}], "data": [{"property": "Amount Concentration (1)", "number": "1.7e-02", "significand": "1.7", "exponent": "-2", "sigfigs": "2", "unit": "g/L"}], "supplemental": [{"property": "Percent mass fraction (2)", "number": "1.5e-03", "significand": "1.5", "exponent": "-3", "sigfigs": "2", "unit": "1"}, {"property": "Mole fraction - Liquid (2)", "number": "9e-04", "significand": "9", "exponent": "-4", "sigfigs": "1", "unit": "1"}]}, {"pntnum": 3, "conditions": [{"property": "Ambient temperature", "number": "2.50e+01", "significand": "2.50", "exponent": "1", "sigfigs": "3", "unit": "&deg;C"}, {"property": "Ambient temperature", "number": "2.982e+02", "significand": "2.982", "exponent": "2", "sigfigs": "4", "unit": "K"}], "data": [{"property": "Amount Concentration (1)", "number": "4.0e-02", "significand": "4.0", "exponent": "-2", "sigfigs": "2", "unit": "g/L"}], "supplemental": [{"property": "Percent mass fraction (2)", "number": "3.7e-03", "significand": "3.7", "exponent": "-3", "sigfigs": "2", "unit": "1"}, {"property": "Mole fraction - Liquid (2)", "number": "2.3e-03", "significand": "2.3", "exponent": "-3", "sigfigs": "2", "unit": "1"}]}, {"pntnum": 4, "conditions": [{"property": "Ambient temperature", "number": "3.50e+01", "significand": "3.50", "exponent": "1", "sigfigs": "3", "unit": "&deg;C"}, {"property": "Ambient temperature", "number": "3.082e+02", "significand": "3.082", "exponent": "2", "sigfigs": "4", "unit": "K"}], "data": [{"property": "Amount Concentration (1)", "number": "1.30e-01", "significand": "1.30", "exponent": "-1", "sigfigs": "3", "unit": "g/L"}], "supplemental": [{"property": "Percent mass fraction (2)", "number": "1.20e-02", "significand": "1.20", "exponent": "-2", "sigfigs": "3", "unit": "1"}, {"property": "Mole fraction - Liquid (2)", "number": "7.1e-03", "significand": "7.1", "exponent": "-3", "sigfigs": "2", "unit": "1"}]}]}]}}
