Description

The invention relates to a device for express analysis of high methanol in alcoholic beverages.

Known devices for the detection of methanol in alcoholic beverages - gas chromatographs, gas chromatography-mass spectrometers, indicator tubes and paper.

The disadvantages of using gas chromatographs, gas chromatography-mass spectrometers and other devices in the express analysis of alcoholic beverages for methanol are their large dimensions and the impossibility of their mobile use.

For indicator tubes, the presence of methanol vapor in exhaled air is necessary, which is not acceptable, since it is understood that alcohol has already entered the body.

Indicator paper on methanol (alkosensor) does not have sufficient selectivity and cannot be used in colored varieties of alcohol.

A known method for the qualitative determination of methanol in aqueous solutions by oxidation of methanol on heated metal catalysts with the formation of formaldehyde by reaction

In this case, the presence of formaldehyde is determined by a sharp unpleasant odor.

If ethanol is present in an alcoholic drink under similar oxidation conditions, acetaldehyde is formed, which smells like ripe apples.

As a catalyst, a wire of Ag, Cu, iron-molybdenum alloys, Zn-Cu alloys or an iron wire galvanically coated with these metals is used, heated to a temperature of 400-700 ° C.

The heated catalyst is immersed in an aqueous solution of alcohol and the presence of formaldehyde or acetaldehyde is determined by the smell of the vapors released (http://en.wikipedia.org/wiki/Formaldehyde);

The objective of the invention is the creation of mobile simple devices for the qualitative determination of the methanol content in alcohol on the basis of improvised means, for example, lighters.

This object is achieved in that the proposed devices consist of a methanol determinant - an indicator-catalyst made in the form of a copper wire or other metal or alloy listed above, and a heater, which can be used as a lighter, placed with the indicator in one housing or combined with it until the indicator catalyst can get into the area of the flame exposure with the possibility of heating it to 600-700 ° C, and by quickly placing the heated indicator catalyst in the studied lkogolny drink, with subsequent determination of the presence of formaldehyde or acetaldehyde formed by odor.

On Fig shows the indicator catalyst with a holder (option 2).

Figure 9 shows a lighter with a blind hole for the indicator-catalyst, bottom view (option 2).

The device according to option 1 (Figs. 1, 2, 3, 4, 5) comprises: a lighter body (1), in which there are: a reservoir (2) with liquefied gas, a nozzle (3) of a burner, an ignition device (4), a partition (5), a longitudinal hole (6) having a side slot (7). A copper wire is inserted into the hole (6) - indicator-catalyst (8), fixed at one end in the holder (9).

The longitudinal hole (6) is made along the housing (1) or partition (5) and has lower (10) and upper (11) outlet openings from the housing (1). The diameter of the hole (6) corresponds to the diameter of the cylindrical part (12) of the holder (9). In the upper part of the housing (1), the hole (6) has a smaller diameter slightly exceeding the diameter of the catalyst indicator wire (8). The upper (11) outlet is located on the upper part of the housing (1) and enters the hole for the exit of the flame of the protective cap of the lighter, parallel to the direction of the nozzle (3). The side slit (7) of the hole (6) does not reach the top of the housing (1) by a distance not exceeding 1 cm.

The copper wire of the indicator-catalyst (8) has a diameter in the range from 0.3 to 0.8 mm and a length slightly less than the length of the lighter body (1), its end falling into the heating zone can be made in the form of a thin spiral.

The holder (9) (FIG. 6) of the indicator catalyst wire (8) has: a cylindrical part (12) with an opening (13) in which the end of the indicator catalyst (8) is rigidly fixed; the neck (14), which enters the slot (7) with the possibility of sliding along it. On the neck (14) there is a protrusion (15) protruding above the side surface of the housing (1).

The device operates as follows.

To determine methanol in alcohol, a portion of alcohol is poured into a small open vessel (a glass, cork, etc.) (if it is not alcohol diluted with water, it must be diluted half with water), the holder (9) is pulled by the protrusion (15) into the top of the lighter along the gap (7). In this case, the wire - indicator-catalyst extends into the hole (11) inside the protective cap for the flame, parallel to the nozzle (3) of the lighter, extends beyond it by 3-4 cm.

They ignite the flame of the lighter and direct it to the indicator-catalyst (8), heating its end to redness. Turn off the lighter and sharply lower the red-hot end of the indicator-catalyst (8) into the vessel with alcohol. In this case, a formaldehyde or acetaldehyde formation reaction occurs and their vapors are released, the smell of which determines the presence or absence of methanol or ethanol in the alcohol sample under study.

After conducting an express analysis, the holder (9) of the indicator-catalyst wire is shifted to the bottom of the lighter and the wire (8) is drawn into the longitudinal hole (6).

According to option 2 (Figs. 7, 8, 9): in the partition (5) or in the wall of the housing (1) there is a blind longitudinal hole (16) having a length almost the entire length of the partition (5) or the housing (1). A catalyst indicator wire (17) is inserted into this hole, fixed at one end in a cylindrical holder (18) having a cap (19). The holder (18) is held in the hole (16) due to friction and is made of heat-resistant plastic. The end of the indicator-catalyst, which is subjected to heating, is made in the form of a spiral (20).

To conduct a rapid analysis of the methanol content in alcohol according to option 2, a portion of alcohol is also poured into a small open vessel, the indicator catalyst (17) is removed from the hole (16), the indicator catalyst (17) is lit, the lighter is lit, and the end is heated to red (20) ) in the flame of a lighter and lower the heated end into a vessel with alcohol, determining the presence of formaldehyde or acetaldehyde by smell.

After the express analysis, the indicator-catalyst (17) is placed back into the hole (16) of the lighter partition (5).
