What are the main uses of cyclohexyl cyanoacetate?
Sodium cyclohexylamino sulfonate, commonly known as cyclamate, is a synthetic sweetener. Its main uses are as follows:
- ** Food industry **: It is widely used in various processed foods, such as in the beverage field, to add sweetness. Some low-calorie or sugar-free beverages often use cyclamate instead of sucrose to meet consumers' needs for sweetness and calorie intake control; in baked goods, it can give bread, cakes and other products suitable sweetness, and has good stability. It is not easy to decompose in the baking high temperature environment, ensuring the sweetness and stability of the product; in the preserved fruit industry, cyclamate can help remove the acid astringency of fruits, improve sweetness and flavor, and prolong shelf life.
- ** Pharmaceutical field **: Some medicines have a bitter taste, adding cyclamate can improve the taste, especially in children's medicines, which is conducive to the acceptance of children and patients. Liquid preparations such as cough syrup, adding cyclamate can make the taste easier to import.
- ** Feed industry **: Adding to animal feed can improve the palatability of feed, stimulate the appetite of livestock and poultry, improve feed intake, promote growth and development, especially for young animals, and can improve their acceptance of feed.
However, the use of cyclamate must strictly follow relevant standards and regulations. Excessive consumption of cyclamate may pose latent risks to human health, such as affecting liver and nervous system functions, especially for people with weak metabolic detoxification ability. When using, producers must precisely control the dosage to ensure consumer health and safety.
What are the physical properties of cyclohexyl cyanoacetate?
Sodium cyclohexylaminosulfonate, also known as cyclamate, is a synthetic sweetener. Its physical properties are as follows:
Looking at it, sodium cyclohexylaminosulfonate is a white crystalline or crystalline powder, like fine snow, with a delicate texture, and it feels pure and flawless when seen by the eye. Touch it, it feels smooth and has no rough tingling. This substance is very soluble in water, and when placed in water, it melts instantly, just like ice and snow merging into a stream, invisible and invisible, but the water has a sweet taste. And when it dissolves in water, it is silent, no bubbles escape, and no precipitation occurs. The resulting solution is clear and transparent, pure and free of impurities. The aqueous solution is neutral, measured by a precise test strip, and the pH value is between 6.5 and 7.5, which is like a quiet lake water, which is calm. Furthermore, sodium cyclohexylamino sulfonate is slightly soluble in ethanol, and when it dissolves in ethanol, the speed is slower, not as fast as in water, but it can also melt with ethanol to form a uniform system. Its melting point is quite high, about 175 ° C, and it needs to be roasted with a hot fire to make it from solid to liquid, which shows its strong stability. This substance is odorless, scented by the nose, without any odor, just like the quiet pool of the forest, silent, but contains unique characteristics. In the food industry, it is often used as a sweetener to add sweetness to many foods.
Is cyclohexyl cyanoacetate chemically stable?
Cyclohexyl sulfamic acid, also known as cyclamate, has relatively stable chemical properties.
Cyclamate is a white crystalline or white crystalline powder, odorless and sweet, with a sweetness of 30 to 40 times that of sucrose. Under normal temperature and pressure, it can maintain a relatively stable state.
Under general food processing conditions, cyclamate has a certain tolerance to heat, light and changes in pH value. In neutral and acidic environments, cyclamate can better maintain its chemical structure and sweetness characteristics. However, under strong acid or strong alkali conditions, cyclamate may undergo hydrolysis to form cyclohexylamine and other products. However, within the usual range of food and beverage production and storage conditions, this degree of hydrolysis is relatively small and will not have a significant impact on its sweetness function.
Cyclamate also has a certain solubility, which is easily soluble in water, slightly soluble in ethanol, and insoluble in organic solvents such as chloroform and ether. This solubility makes it easy to apply to various liquid or semi-solid foods, and evenly dispersed to play a sweet role.
In addition, the stability of cyclamate is also reflected in its inability to chemically react with common food ingredients, and it can coexist well with other sweeteners, flavors, preservatives and other additives, which makes it a widely used sweetener in the food industry.
What are the synthesis methods of cyclohexyl cyanoacetate?
Sodium cyclohexylamine sulfonate is one of the sweeteners. The synthesis method has many paths, and each has its advantages and disadvantages, all of which need to be selected according to the specific situation.
One is the cyclohexylamine method. First, cyclohexylamine is mixed with sodium hydroxide solution to form cyclohexylamine sodium salt, and then sulfur dioxide is passed. The reaction of the two can produce sodium cyclohexylamine sulfonate. This process requires good control of the reaction temperature, pressure and material ratio. If the temperature is too high, the side reaction will increase and the yield will decrease; if the temperature is low, the reaction will be slow. The pressure also affects the reaction process, and the appropriate pressure can promote the positive progress of the reaction. Only with accurate material ratio can higher yield and purity products be obtained. This method is easy to find raw materials, and the operation is not complicated, but the product purification is slightly difficult, and there are many by-
The second is the cyclohexanol method. Cyclohexanol is used as the starting material, chlorinated into chlorocyclohexane, and then reacted with sodium sulfite to obtain sodium cyclohexyl sulfonate. The reaction conditions of this path are mild and the product purity is high. However, chlorine is required for the chlorination step. Chlorine is highly toxic and corrosive, which requires strict equipment requirements, and strict protection is required during operation to avoid safety accidents caused by chlorine leakage.
The third is the cyclohexene method. Under the action of catalyst, cyclohexene and sodium bisulfite can be added to obtain sodium cyclohexyl sulfonate. This method has high atomic utilization rate, environmental friendliness, and conforms to the concept of green chemistry. However, the choice and preparation of catalysts are very important, and efficient catalysts can reduce the reaction conditions, increase the reaction rate and yield. However, some catalysts are expensive or complex to prepare, limiting their large-scale application.
What are the precautions for cyclohexyl cyanoacetate during storage and transportation?
Sodium cyclohexylaminosulfonate, commonly known as cyclamate, has several important things to pay attention to during storage and transportation.
Although its properties are stable, cyclamate may degrade in high temperature environments, causing its sweetness to weaken or flavor to vary. Therefore, when storing, it should be placed in a cool place, away from direct sunlight and heat sources, to prevent excessive temperature from affecting the quality. The temperature of the warehouse should be controlled below 25 ° C.
Furthermore, the humidity of the air should not be underestimated. Cyclamate has a certain hygroscopicity. If the ambient humidity is too high, it is easy to cause it to agglomerate, which not only affects the appearance, but also inconvenient to disperse when taken, or affects the subsequent use effect. Therefore, it should be stored in a dry place, and the relative humidity should not exceed 60%.
When transporting, the first thing to ensure is that the packaging is intact. Cyclamate is mostly packed in bags or barrels, and the bumps and vibrations during transportation may cause damage to the packaging and leakage of cyclamate. If it leaks outside, it will not only cause material waste, but also pollute the surrounding environment. When loading, carefully check the packaging. If there is any damage, replace it immediately.
At the same time, the transportation tool should also be clean, dry, and odor-free. Cyclamate is a food additive. If the transportation tool is unclean, there will be residual contaminants, or it will cause cyclamate to be contaminated. If there is a peculiar smell, the peculiar smell or adsorption on the cyclamate will affect its quality. And during transportation, it should also be protected from rain and moisture, tightly covered, and protected from external adverse factors.
In addition, cyclamate should not be mixed with toxic, harmful and corrosive substances during storage and transportation. Because it is used in the food field, if it comes into contact with such items, it is vulnerable to contamination and endangers food safety. It must be stored and transported in strict accordance with relevant regulations to ensure its quality and safety.
