What are the physical properties of (2Z) -1,1,1,4,4,4-hexafluorobutyl-2-ene?

(2Z) - 1,1,4,4,4-hexafluorobutyl-2-alkyne, this substance has the following physical properties:
It is usually a colorless gas at room temperature and pressure, and has a faint odor similar to other halogenated hydrocarbons in terms of odor. When it comes to the phase state, the normal state is gaseous, which is easy to diffuse. The melting point is about -139.3 ° C. Under this low temperature condition, it will solidify into a solid state, and the appearance of the solid state may be white like an icy solid. The boiling point is at -22.7 ° C, and it will quickly vaporize above this temperature.
In terms of density, the density of the gaseous state is greater than that of the air, which is about twice the density of the air, which makes it tend to sink in the air. Its solubility is poor, and it is extremely difficult to dissolve in water, because the substance is a non-polar molecule, and water is a polar solvent, according to the principle of "similar phase dissolution"; but it is soluble in some organic solvents, such as carbon tetrachloride, chloroform and other non-polar or weakly polar organic solvents.
In addition, the critical temperature of the substance is about 144.7 ° C, the critical pressure is about 3.39 MPa, and in the critical state, the gas-liquid two-phase interface disappears, presenting unique physical properties. These physical properties have an important impact on its storage, transportation and use. Because of its low boiling point, storage requires low temperature and high pressure conditions; density is greater than air, and it is easy to accumulate in low places in poorly ventilated environments, bringing latent risks.

Is (2Z) -1,1,1,4,4,4-hexafluorobutyl-2-ene chemically stable?

(2Z) -1,1,1,4,4,4-hexafluorobutyl-2-ene is a new type of fluoroolefin. Its chemical properties are relatively stable for three reasons.

The first reason is that the structure is unique. In the molecule of (2Z) -1,1,1,4,4,4-hexafluorobutyl-2-ene, fluorine-containing groups are connected on both sides of the double bond. The fluorine atom is extremely electronegative and the C-F bond energy is high, so that the C = C double bond electron cloud is attracted by the fluorine atom, reduces the density of the double bond electron cloud, weakens the offensive ability of the electrophilic reagent, and is not prone to electrophilic addition reactions, and the chemical properties tend to be stable.

The second is the shielding effect of the fluorine atom. The fluorine atom has a small radius and strong electronegativity This shielding layer prevents external reagents from contacting carbon atoms, reducing molecular chemical reactivity and enhancing stability.

Furthermore, there may be a conjugation effect between the double bond and the fluorine atom in the molecule, and the electron cloud is delocalized within the molecule, which reduces the molecular energy, makes the structure more stable, and is not easy to participate in the chemical reaction.

In summary, due to the unique structure, shielding effect and conjugation effect of fluorine atoms, (2Z) -1,1,4,4,4-hexafluorobutyl-2-ene is chemically stable.

What are the precautions for (2Z) -1,1,1,4,4,4-hexafluorobutyl-2-ene in the production process?

In the production process of (2Z) -1,1,1,4,4,4-hexafluorobutyl-2-ene, all kinds of precautions are crucial, which are related to the safety and effectiveness of production, and should be paid attention to in detail.

First, the storage and use of materials should be extremely cautious. This substance has certain chemical activity and should be stored in a cool, dry and well-ventilated place, away from fire, heat and strong oxidants. When taking it, follow precise operating procedures to ensure that the material is not contaminated and the dosage meets the production requirements to prevent reaction deviations or safety accidents due to material problems.

Second, the control of reaction conditions is the core. Factors such as temperature, pressure and catalyst dosage have a profound impact on the reaction process and product purity. If the temperature is too high or too low, the reaction rate may be abnormal, or by-products may be formed; improper pressure will also affect the reaction balance. Therefore, it is necessary to use sophisticated equipment to monitor and regulate the reaction conditions in real time, so that the reaction can proceed in the best state.

Third, personnel protection and safety measures are indispensable. This substance may be toxic and irritating, and operators must wear appropriate protective equipment, such as protective clothing, gloves, goggles and gas masks, to avoid direct contact with the human body. Production sites should also be equipped with various emergency treatment facilities, such as eye washers, sprinklers and fire extinguishing equipment, just in case.

Fourth, exhaust treatment should not be ignored. The exhaust gas generated in the production process, or containing unreacted raw materials and harmful by-products, if directly discharged, will not only damage the environment, but also waste resources. Therefore, it is necessary to set up an efficient exhaust gas treatment system, through absorption, adsorption or catalytic conversion and other means, the exhaust gas will be properly treated, and can be discharged after reaching the standard.

Fifth, the maintenance and overhaul of equipment is crucial. The long-term operation of production equipment is prone to wear and tear, leakage and other conditions, which affects the stability and safety of production. The equipment should be comprehensively inspected and maintained regularly, and damaged parts should be replaced in time to ensure that the equipment is always in good operating condition.

What are the environmental effects of (2Z) -1,1,1,4,4,4-hexafluorobutyl-2-ene?

The environmental impact of (2Z) -1,1,4,4,4-hexafluorobutyl-2-alkyne is related to many aspects. If this substance is released into the atmosphere, its fluorine-containing properties may cause special effects. Fluorine atoms are extremely reactive or react in complex reactions with other components of the atmosphere.

First, at the ozone layer level, some fluorinated compounds can participate in the chain reaction that destroys the ozone layer. Although the specific reaction mechanism of (2Z) -1,1,4,4,4-hexafluorobutyl-2-alkyne may be different, its fluorine-containing nature makes it latent risk. Once it enters the stratosphere, under specific photolysis conditions, fluorine atoms may emerge free and interact with ozone molecules, causing ozone decomposition, weakening the ozone layer's UV shielding function, thereby increasing the intensity of ultraviolet radiation to surface organisms, threatening biological health, such as the incidence of human skin cancer or increase, animal and plant physiological functions may also be disturbed.

Secondly, in terms of greenhouse effect, fluorinated organic compounds have a strong greenhouse effect potential. (2Z) -1,1,4,4,4-hexafluorobutyl-2-alkyne can persist in the atmosphere for a long time, absorb and re-radiate infrared rays, and exacerbate the earth's greenhouse effect. This may lead to more extreme global climate, accelerated melting of glaciers, rising sea levels, and threats of floods in coastal areas; changing climate patterns, uneven distribution of precipitation, frequent droughts and floods, affecting agricultural production and ecological balance.

Furthermore, if it enters the water body or soil environment, it may be difficult to degrade rapidly due to chemical stability. In water bodies, it may affect the survival and reproduction of aquatic organisms and interfere with the balance of aquatic ecosystems; in soil, or change the physical and chemical properties of soil, affecting the absorption of nutrients by plant roots and hindering plant growth and development.
