Device for rapidly detecting methanol content and preparation and detection method thereof

The invention discloses a device for rapidly detecting methanol content and a preparation and detection method thereof. The detection device comprises a detection base material and a detection test solution, and is characterized in that the detection base material contains alkaline substances, and the detection test solution is a benzene solution of naphthol benzene. The detection test solution is dropwise added on the detection base material for infiltration, the to-be-detected sample is dropwise added on the detection base material after drying, and the detection base material is compared with the standard colorimetric sample strip after color change, so that the content of methanol in the sample can be rapidly detected. According to the invention, the methanol content in the vehicle gasoline can be rapidly detected on the site of a gas station and the like, the test paper can judge the detection result through naked eye observation and colorimetry, and the test paper has the advantages of simple and rapid
