Description

Technical Field

[0001] The invention relates to the technical field of denatonium benzoate production, in particular to a denatonium benzoate concentration and refining technology. Background Art

[0002] Denatonium Benzyl, also known as bitter essence, is a very bitter chemical substance, and its bitterness is much higher than other known bitter substances. It is a white crystalline powder with a melting point of 163-170°C, odorless, and has a very strong bitter taste. It is easily soluble in water, ethanol, ethylene glycol, etc., and its aqueous solution is neutral. The existing granular powder form of Denatonium Benzyl is inconvenient to carry, and the concentration is low, which cannot meet the diverse usage needs. Summary of the invention

[0003] In view of this, in order to solve the problems existing in the technical background, the present invention proposes a concentrated refining technology of benzyl denatonium, and the specific technical scheme is as follows:

[0004] A denatonium benzoate concentration and refining technology comprises the following steps:

[0005] Step 1: Pour the oil into a glass melting cup and precisely control the oil temperature between 150 and 200 degrees. When the oil temperature reaches this range, slowly pour the pre-prepared granular powdered benzyl denatonium into the heated vegetable oil to ensure even mixing and avoid local overheating.

[0006] Step 2: Continue heating for 2 to 5 minutes while maintaining the oil temperature at 150 to 200 degrees. During this process, the denatonium benzoate particles gradually melt into liquid, but due to their chemical properties, they will not mix with the vegetable oil. Instead, they will settle at the bottom of the oil, forming a stratified effect of a concentrated liquid layer. The original impurities in the raw materials are effectively separated due to the density difference, ensuring the purity of the final product.

[0007] Step 3: After layering, pour the vegetable oil mixture containing liquid denatonium benzoate into a pre-prepared high-temperature resistant metal mold. The mold must be selected to ensure that it can withstand high temperatures and is easy to demold. Wait for the mixture to cool naturally, during which time the denatonium benzoate will gradually solidify due to the drop in temperature. After complete cooling, demold the mold to obtain a high-concentration block of denatonium benzoate.

[0008] Furthermore, in steps 1 to 3, the natural vegetable oil is heated to 170 degrees Celsius.

[0009] Furthermore, in step 2 and step 3, the oil temperature is heated to 3 minutes.

[0010] Furthermore, the oil is natural vegetable oil.

[0011] The above technical solution has the following beneficial effects:

[0012] The present invention effectively treats and processes low-concentration denatonium benzoate powder solids, and then converts them into high-concentration block-shaped denatonium benzoate concentrates. The problem of the bulky and easily scattered powdered raw materials of denatonium benzoate in the traditional form is solved, and now it is replaced by a compact and stable block concentrate, which greatly facilitates users to carry and store in daily use.

[0013] The invention performs filtering and layering steps through natural vegetable oil and controls various parameters of each step to ensure that the high-concentration block-shaped denatonium benzoate concentrated block finally obtained has high purity, stable structure and is not easily affected by moisture or deterioration.

[0014] The concentrated and purified denatonium benzoate can be used in laboratories, medical or industrial production fields as needed, meeting the needs of specific application scenarios. DETAILED DESCRIPTION

[0029] After purification, purity testing can be performed: high performance liquid chromatography (HPLC), gas chromatography (GC) and other analytical methods are used to test the purity of denatonium benzoate to ensure that it meets quality requirements.

[0030] Toxicity assessment: Although denatonium benzoate is widely used as a bittering agent, the effects of long-term exposure to it on the human body are not fully understood. Therefore, a toxicity assessment of the product is required during the concentration and refining process to ensure its safety.
