6. A method of using a methyl acetate purity test apparatus, the method of using a methyl acetate purity test apparatus being adapted to a methyl acetate purity test apparatus according to any one of claims 1 to 5, comprising the steps of:
s1, pouring methyl acetate solution into a placing cylinder (3) during purity detection, setting and controlling the temperature of a heating chassis (2) through a control panel, setting the temperature to fifty-seven degrees, after the placing cylinder (3) is placed at the upper end of the heating chassis (2), enabling the top end of the placing cylinder (3) to be in contact with the periphery of the bottom end of a sealing gasket (504), starting an electric telescopic rod (501) to move a waterproof motor (503) into the placing cylinder (3), starting the waterproof motor (503) to drive a stirring head (502) to rotate in the placing cylinder (3), increasing the efficiency of methyl acetate temperature rising detection, and because the boiling points of acetone and acetaldehyde contained in the methyl acetate are fifty-sixteen degrees respectively and fifty-seven degrees, the acetone and the acetaldehyde in the methyl acetate boil and evaporate after the temperature reaches fifty-seven degrees, the acetone and the acetaldehyde float upwards after the evaporation and are gathered at the bottom end of the sealing gasket (504), because the bottom end of the sealing gasket (504) is of a horn-shaped structure, the impurities in the methyl acetate flow into the receiving ring opening (505) after the concentration is too much, when the purity of the methyl acetate is not high, the impurities in the methyl acetate are more and the impurities are evaporated, the liquid gathered into the receiving ring opening (505) is more, when the gathered liquid is too much, the contact rings (507) at two sides are in a communicating state through the conductivity of the liquid, an indicator lamp outside a control panel is started, the purity of the methyl acetate is not high, and the qualified standard is not reached for workers, when the top end of the placing cylinder (3) is in contact with and pressed against the bottom end of the sealing gasket (504), the sealing gasket (504) is compressed, the discharge port (14) is sealed, when the placing cylinder (3) is separated from the bottom end of the sealing gasket (504), the sealing gasket (504) is restored, and liquid received in the receiving ring opening (505) through the discharge port (14) is discharged into the receiving frame (506);
S2, when the purity detection is continuously carried out on the inside of the methyl acetate, the temperature is raised to sixty degrees through the heating chassis (2), because the boiling point of the methyl acetate is fifty seven degrees, the methyl acetate boils after the temperature reaches sixty degrees and becomes water vapor to gather at the bottom end of the sealing gasket (504), the water vapor gathers in the inside of the receiving ring opening (505), the water suction pump (604) is started to collect the methyl acetate liquid into the collecting frame (602) through the collecting pipe (601), the purity of the methyl acetate is judged according to the residual liquid water in the placing cylinder (3), if the residual liquid water is excessive, the purity of the methyl acetate is lower, otherwise, the residual liquid water is less, and the purity of the methyl acetate is higher.
