Its appearance is usually a colorless to light yellow liquid with a weak odor. It can be seen from its chemical structure containing cyanide and hydroxyl groups that it has both characteristics.
Let's talk about cyanyl first, which makes it reactive. Under suitable conditions, cyanyl can undergo hydrolysis. In case of acid or alkali, cyanyl will gradually hydrolyze to form amides, and then further hydrolyze to form carboxylic acids and ammonia. Take hydrolysis under alkaline conditions as an example. The alkali provides hydroxide ions and attacks the carbon atoms of the cyanyl group. After a series of intermediate steps, carboxylate and ammonia are finally formed. This reaction is an important method for preparing the corresponding carboxylic acid.
The hydroxyl group gives it hydrophilicity and can form hydrogen bonds with water molecules, so β-cyanoethanol can be mutually soluble with water in a certain proportion. At the same time, the hydroxyl group can participate in the esterification reaction. Under acid catalysis, it can react with carboxylic acids. The hydrogen atom in the hydroxyl group combines with the hydroxyl group of the carboxylic acid to form water, and the remaining part is connected to form an ester. For example, when reacted with acetic acid, beta-cyanoethyl acetate will be formed.
In addition, β-cyano The hydrogen atom of the hydroxyl group can be replaced by other groups, such as reacting with halogenated hydrocarbons under basic conditions, and the halogen atom replaces the hydroxyl hydrogen to form a new organic compound. This reaction is used in organic synthesis to introduce different functional groups and expand the diversity of molecular structures. In short, β-cyanoethanol is widely used in organic synthesis, chemical industry and other fields due to its rich chemical properties of cyano and hydroxyl groups.

To prepare 2 - (2 - cyanoethoxy) ethanol, the synthesis method is as follows:
First take an appropriate amount of acrylonitrile and place it in a clean reaction vessel. Another amount of ethylene glycol is slowly poured into the container containing acrylonitrile. The reaction of the two requires the participation of suitable catalysts, generally basic catalysts such as sodium hydroxide can be selected. Under suitable temperature and pressure conditions, the addition reaction of the two occurs.
When reacting, pay close attention to the change of temperature. If the temperature is too high, the side reactions will increase and the product will be impure; if the temperature is too low, the reaction rate will be slow and take a long time. Generally speaking, the reaction temperature is preferably controlled at 50 ° C to 70 ° C, and the pressure can be maintained near normal pressure.
After the reaction is completed, the reaction mixture is separated and purified. Distillation can be used to remove unreacted acrylonitrile and ethylene glycol. Since the boiling points of acrylonitrile and ethylene glycol are different from the product 2 - (2 - cyanoethoxy) ethanol, they can be separated by distillation. After that, the product is further purified by extraction to obtain high-purity 2 - (2 - cyanoethoxy) ethanol.
This synthesis method, although seemingly clear steps, in practice, the control of the reaction conditions is extremely critical, and a slight error may affect the yield and purity of the product. Therefore, the operator needs to exercise caution and precisely control the reaction parameters.

Fu 2 - (2 -cyanoethyl hydroxyl) - Whether it is harmful to the environment and human body is an important matter for people's livelihood. Today, it is stated in the ancient text of "Tiangong Kaiwu".
Cyanoethyl hydroxyl substances may be useful in the field of chemical industry. However, its impact on the surrounding environment and human body cannot be ignored.
Looking at the natural environment, if this substance is wantonly released outside, or soils the soil. Soil, the foundation of all things, if its quality changes, the growth and life of plants will be disturbed by it. Or it will cause the plant to fail, or even die prematurely, and then disrupt the ecological order. And when it enters the water body, water is the source of life, and aquatic spirits depend on it. If the water is polluted, fish, turtles, shrimp, crabs and other aquariums will be difficult to survive, and it will also harm the people who live by water. There is no water to use, and their livelihood is worrying.
As for the human body, if you touch it carelessly, it may cause skin discomfort, itching, redness and swelling; in severe cases, it may damage the texture and damage the viscera. If you inhale its volatile gas, the lungs will bear the brunt, or cause respiratory diseases, cough and chest tightness, and damage the function of the lungs for a long time. If you eat it by mistake, the harm will be even more serious, and the transportation of the viscera may be messed up, endangering your life.
Therefore, in 2 - (2 - cyanoethyl hydroxyl) this material, be cautious. When using it, there must be a comprehensive method to prevent it from leaking into the environment and preventing harm to the common people. Those who operate should also strictly abide by regulations and use protective equipment to ensure their own safety. In this way, the purpose of using things without harming the environment and people can be achieved, and the whole ecology and human life can be safe.
