1% 2C4-diene-2-isothiocyanate phenyl ester, this material has unique physical properties. At room temperature, it is often in a liquid state, and the appearance is mostly colorless to light yellow transparent, like a clear liquid, pure and free of variegated colors. Under light, or shimmering, it is smart and shining.
Looking at its smell, it is very strong and unique, with strong irritation. Smell it, as if it can reach the heart and spleen, causing strong discomfort in the nose and throat, which is unforgettable. This irritating smell is one of its remarkable characteristics.
Its density is higher than that of water. If it is placed in one place with water, it can be seen that it is like a stable weight, slowly settling at the bottom of the water. The two are distinct and there is no confusion.
Furthermore, solubility is also an important physical property. This substance is soluble in many organic solvents, such as ethanol, ether, etc., and can be uniformly dispersed in it, just like a fish entering water, naturally and harmoniously. However, its solubility in water is very small, as if it is incompatible with water. When the two meet, they can only coexist for a short time, and then delaminate, and the boundaries are clear.
In addition, the boiling point and melting point of this substance are also specific values. The boiling point is within a certain temperature range, and when heated to that point, the substance changes from liquid to gaseous state, and under a specific pressure environment, this temperature value is relatively stable. The same is true for the melting point. When the temperature drops to a specific value, the substance gradually changes from liquid to solid state. This specific temperature is also its inherent physical property, reflecting the characteristics of the internal structure of the substance and the forces between molecules. These physical properties are of crucial significance in many fields such as industrial production and chemical research, laying a solid foundation for their application and research.

This compound is acidic and alkaline. Its structure contains a carboxyl group, and the hydroxyl hydrogen in the carboxyl group is acidic. It can partially ionize hydrogen ions in solution, exhibit acidity, and can neutralize with bases, like reacting with sodium hydroxide to form corresponding carboxylic salts and water.
Because the structure contains unsaturated carbon-carbon double bonds, this compound has addition reaction characteristics. Under suitable catalyst and reaction conditions, the double bond can be added with hydrogen, halogen elementals, etc. If it is added with hydrogen under nickel catalysis, the double bond becomes a single bond, making the molecule more saturated.
The compound can also undergo substitution reactions. The hydroxyl group in the carboxyl group can be replaced by other atoms or groups, such as esterification with alcohols catalyzed by concentrated sulfuric acid and heated to form esters and water. And the hydrogen atoms on the adjacent carbon atoms of the carbon-carbon double bond can also be replaced under certain conditions.
Because of its carbon-carbon double bond, under certain conditions, the double bonds can be broken and connected to each other, polymerization occurs, and polymer compounds are formed.
In addition, this compound is flammable. Containing carbon, hydrogen and other elements, it burns in sufficient oxygen to generate carbon dioxide and water, and at the same time releases heat.

The synthesis method of 1% 2C4-diene-2-isothiocyanate benzyl ester is related to the field of organic chemistry, which is quite complicated and requires fine operation. The following are several common methods:
First, benzyl alcohol is used as the starting material. First, benzyl alcohol is converted into halogenated benzyl, and the halogenated atom is often chlorine or bromine. This reaction usually uses a halogenating agent, such as phosphorus trichloride, phosphorus pentachloride or hydrohalic acid, under appropriate conditions, when combined with benzyl alcohol, halogenated benzyl can be obtained. Then, the nucleophilic substitution reaction occurs between the halogenated benzyl and the thiocyanate. Generally, potassium thiocyanide or sodium thiocyanide is used as a reagent and carried out in a suitable solvent such as ethanol and acetone to obtain 1% 2C4-diene-2-benzyl isothiocyanate.
Second, benzyl amine is used as the starting material. Benzyl amine is first reacted with carbon disulfide to form a dithiocarbamate intermediate. This reaction is usually carried out under basic conditions, such as sodium hydroxide or potassium hydroxide in an alcohol solution. The resulting intermediate is then reacted with halogenated hydrocarbons. The halogen atom of halogenated hydrocarbons is also chlorine or bromine. Through nucleophilic substitution reaction, the final target product is 1% 2C4-diene-2-benzyl isothiocyanate.
Third, benzaldehyde is used as raw material. Benzaldehyde first reacts with hydroxylamine to form an oxime, which is then converted into nitrile by dehydration reaction. Under the action of thioreagents, such as with phosphorus pentasulfide, nitrile groups can be converted into isothiocyanate groups, thereby synthesizing 1% 2C4-diene-2-benzyl isothiocyanate.
These synthesis methods have their own advantages and disadvantages, and should be carefully selected according to the actual situation, such as the availability of raw materials, the difficulty of reaction conditions, yield and purity requirements. And the synthesis process must strictly follow the safety regulations of chemical experiments to ensure the safety of operation.

1% 2C4-diene-2-isothiocyanate This substance is highly toxic and highly irritating. During use, the following principles must be adhered to:
First, comprehensive protection. When handling this substance, it is necessary to wear professional protective clothing and strictly select protective gloves. This glove must have strong corrosion resistance and penetration resistance, such as those made of nitrile rubber. Face protection is also indispensable. Wear a full-face gas mask to closely protect the respiratory tract and eyes to ensure that no harmful gases or particles invade.
Second, the environment is suitable. The operation should be placed in a well-ventilated place, and the best choice is a chemical fume hood equipped with a strong ventilation system. The ventilation system shall not change air less than [X] times per hour to ensure that harmful gases are discharged in time, maintain fresh air in the operating environment, and prevent the risk of poisoning caused by gas accumulation.
Third, use caution. When taking, use precise and suitable appliances, such as pipettes, droppers, etc. When opening the container, the action should be slow to prevent the contents from splashing. If you need to measure, be sure to operate according to the precise scale to prevent errors.
Fourth, store properly. Store in a cool, dry and well-ventilated place, away from fire and heat sources. Store separately from oxidants, acids, alkalis and other substances, and do not mix them to avoid violent reactions. The storage temperature should be controlled between [X] ° C and [X] ° C, and the humidity should be maintained below [X]%.
Fifth, emergency preparedness. The corresponding emergency treatment equipment and medicines should be prepared near the workplace, such as eye washers, emergency spray devices, antidotes, etc. The eye wash device must be guaranteed to be activated within 10 seconds, and the coverage area of the spray device should reach more than [X]% of the operating area. Staff should also be familiar with the emergency treatment process and practice regularly so that they can respond quickly in case of emergencies.
