Methanol → Hexanoic acid, 6-hydroxy-, methyl ester

温度

300 °C

Nylon 6 (0.1 g), methoxyacetic acid as a carboxylic acid (0.45 g) and methanol (3.0 g) were added to a 10 mL volume reactor equipped with a tube (outer diameter: ⅜ inches, inner diameter: 7.53 mm, length: 23 cm), nitrogen substitution was conducted at room temperature, and the reactor was sealed. The reactor was put into an electric furnace heated to 300° C. (pressure: 16.3 MPa), and the change over time was measured. In the measurement, the obtained reaction mixture and 1-hexanol as an internal standard substance were weighed and used as analysis samples for a gas chromatography analysis. An integral value was calculated by a gas chromatography analysis, and a table of a standard curve was prepared and the yield of methyl 6-hydroxycaproate was obtained therefrom. The result is shown in Table 3.
