Quick detection test paper for methanol content in spirit

Abstract

The utility model discloses a quick detection test paper for methanol content in spirits. The quick detection test paper has a lamellar structure composed of a molecular sieve, a discoloration test paper encountering methanol, and a transparent plastic adhesive tape. The discoloration test paper encountering methanol is completely coated and stuck on the molecular sieve by the transparent plastic adhesive tape; the molecular sieve can only make methanol molecules in spirits pass through and contact with the discoloration test paper to generate discoloration reaction; through the comparison of the transparent plastic adhesive tape and a standard color board, the content of methanol in spirits can be qualitatively detected out. The utility model has the advantages of simple structure, easy carrying, visual viewing and accurate qualitativeness. The quick detection test paper can be widely used for detecting at any time methanol content in the spirits by shops, hotels, quality detecting departments and spirit drinking persons.

Description

Methanol in wine content quick detection test paper
The utility model relates to quality of white spirit and detects the articles for use technical field, is a kind of methanol in wine content quick detection test paper furtherly.
At present, the mensuration of the detection of quality of white spirit, particularly methanol content mainly adopts the methanol oxidation method, operates more loaded down with trivial detailsly, and still rests on laboratory level, is difficult to popularization and application.Though new detecting instrument is developed, because volume is bigger, detection time is longer, price height in addition, and also inconvenience is promoted the use of.
The utility model provides a kind of methanol in wine content quick detection test paper, and purpose is intended to solve the weak point that above-mentioned methyl alcohol detection method exists.
For finishing the purpose of this utility model, concrete design is as follows: utilize that the molecular diameter of ethanol and methyl alcohol varies in size in the liquor, select the only molecular sieve of porous methyl alcohol for use, methyl alcohol is separated, by meeting the colour developing detection paper that alcohol reddens, and judge the content of methyl alcohol.
The utility model by molecular sieve 1, meet alcohol colour developing test paper 2, transparent plastic adhesive tape 3 is formed layer structure, it is characterized in that: meet the alcohol test paper 2 that develops the color and coat fully by transparent plastic adhesive tape 3 and be bonded on the molecular sieve 1 and constitute layer structure.Molecular sieve 1 is Na-Type Mordenit or woods moral 4A molecular sieve, and the methanol molecules in the liquor is seen through, meet alcohol colour developing test paper 2 characteristics and redden for meeting alcohol, as: oxine acid vanadium black test paper, the yellow test paper of ammonium ceric nitrate.
Good effect of the present utility model is: adopt molecular sieve to filter methanol molecules thoroughly, by meeting the alcohol colour developing detection paper that reddens, simple in structure, observe directly perceived, carry easily, easy to operate, qualitative accurately, can be widely used in the content that shop, hotel and quality testing department, liquor drinking person detect methanol in wine at any time.
Fig. 1 is a structure principle chart of the present utility model.
Further narrate the utility model below in conjunction with accompanying drawing:
With reference to Fig. 1:
The molecular sieve of 1--sheet for sodium silk zeolite or woods moral 4A molecular sieve, can make methyl alcohol penetrate, can not adsorb ethanol molecule.
2--meets alcohol colour developing test paper, 1. uses oxine acid vanadium black test paper (meeting alcohol reddens).2. with the yellow paper of ammonium ceric nitrate system (meeting alcohol reddens).3. with the test paper (meeting pure variable color) of other slaine system that can develop the color.
3--transparent plastic adhesive tape prevents that ethanol from soaking into from the back side and the colour developing test paper reacts.
The utility model drops in the surface of molecular sieve with tested liquor, at this moment in use, methanol molecules in the liquor filters molecular sieve thoroughly and contacts with the colour developing test paper, metachromasia taking place, compare by transparent plastic adhesive tape and Standard colour board, can detect the content of methyl alcohol qualitatively.
