Problems solved by technology

In these methods, the odorous substances are not uniform, and different batches of cat litter, human excrement, stinky water or household garbage have different odor levels, resulting in different odor standards, which are easy to determine the results of the evaluation of the deodorizing substances. Accuracy makes a big difference

Embodiment 1

[0037] Configure the odor composition to simulate toilet odor by the following formula: 20 mass parts of saturated hydrogen sulfide solution, 1 mass part of 3-methylindole, 0.5 mass part of indole, 2 mass parts of ammonia solution, 2 mass parts 1.5 parts by mass of trimethylamine solution, 1.5 parts by mass of n-valeric acid, 47 parts by mass of propylene glycol and 26 parts by mass of water, wherein the concentration of the ammonia solution is 25%, and the concentration of the trimethylamine solution is 30%. The configuration method is: mixing propylene glycol and water and stirring evenly, adding saturated hydrogen sulfide solution, 3-methyl indole, indole, 25% ammonia solution, 30% trimethylamine solution and n-valeric acid under stirring.

Embodiment 2

[0039] Configure the odor composition according to the following formula to simulate the odor of the landfill: 10 mass parts of saturated hydrogen sulfide solution, 4.5 mass parts of methyl mercaptan, 12 mass parts of ammonia solution, 7.5 mass parts of trimethylamine solution, 2 mass parts acetic acid, 32 parts by mass of glycerin and 32 parts by mass of water, wherein the concentration of the ammonia solution is 25%, and the concentration of the trimethylamine solution is 30%. The preparation method is as follows: mix glycerin and water and stir evenly, add saturated hydrogen sulfide solution, methyl mercaptan, 25% ammonia solution, 30% trimethylamine solution and acetic acid under stirring.

Embodiment 3

[0041] Configure the odor composition according to the following formula to simulate the smell of stinky ditch: 32 mass parts of saturated hydrogen sulfide solution, 1 mass part of 3-methylindole, 8 mass parts of trimethylamine solution, 2 mass parts of n-pentyl acid, 38 parts by mass of propylene glycol and 19 parts by mass of water, wherein the concentration of the trimethylamine solution is 30%. The configuration method is as follows: mixing propylene glycol and water and stirring evenly, adding saturated hydrogen sulfide solution, 3-methyl indole, 30% trimethylamine solution and n-valeric acid under stirring.

Abstract

The invention discloses an odorous composition which is used for odorous standard substances. The odorous composition comprises an odorous ingredient providing odor and a solvent, and mass of the odorous ingredient accounts for 1-20% that of the odorous composition. Through the above mode, the odorous composition can simulate various typical living stink and can be conveniently used for evaluating deodorizing effect of deodorants and deodorizing products.

Description

technical field [0001] The invention relates to the field of odor treatment, in particular to an odor composition. Background technique [0002] Malodorous gas is a kind of gaseous substance, which produces discomfort or disgust through the human olfactory organs; malodorous gas seriously affects the ecological environment and human health, and is easy to cause the growth of bacteria and viruses. These malodorous substances mainly come from garbage corruption Odors produced, odors from livestock or livestock farms, toilet odors, and stinky sewers, etc. [0003] Aiming at these malodorous substances, various deodorants and deodorizing products have been developed to combat stench; however, there is still no uniform method for evaluating the deodorizing effect of deodorants and deodorizing products. Some are effective against the odor of animal excrement, and cat litter is used as the odor substance to test the effect of the deodorant when evaluating the effect; some use huma...
