What are the physical properties of 2-n-Pentylthiophene?

2-N-pentylthiophene is one of the organic compounds. Its physical properties have many characteristics.

Looking at its appearance, at room temperature, it often appears as a colorless to light yellow transparent liquid, just like a clear spring, pure and clear, with a soft luster and no turbidity at all.

When it comes to boiling point, it is about 230-240 ° C. This number of boiling points makes it light from liquid to gaseous under a specific temperature environment, if it emerges. Just like a specific heat, the state of matter changes miraculously.

In terms of melting point, it is roughly around -40 ° C. The lower melting point makes it start to solidify in a relatively low temperature environment, just like hard ice needs a cold square knot.

As for the density, it is about 0.96-0.98g/cm ³, which is slightly lighter than water, such as wood leaves floating on the water surface, and occupies the lighter end of the density scale.

In terms of solubility, it can be soluble in common organic solvents, such as ethanol, ether, acetone, etc., just like fish entering water and melting freely; however, the solubility in water is extremely low, just like oil and water are difficult to mix, and the boundaries between the two are clear.

Its vapor pressure is low, indicating that the volatility is relatively weak and it is difficult to dissipate quickly in the air like light smoke. The refractive index of

is about 1.51 to 1.52. When light travels through a tortuous path, a unique refraction phenomenon occurs, which is also one of its unique physical characteristics.

What are the synthesis methods of 2-n-Pentylthiophene?

The synthesis method of 2-n-pentylthiophene has been known for a long time. First, thiophene and bromo-n-pentane are used as raw materials. In an alkaline environment, the nucleophilic substitution reaction can be obtained. For alkalis, such as potassium carbonate, in organic solvents, the two interact, and the hydrogen atom of thiophene is replaced by n-pentyl group, so it becomes 2-n-pentylthiophene. This reaction has mild conditions and high yield. However, the raw materials need to be pure, and the operation should be cautious to avoid side reactions.

Furthermore, starting with thiophene, lithium thiophene derivatives are first prepared, and then mixed with n-pentyl halide. Lithium thiophene has strong nucleophilicity. When encountering n-pentyl halide, the halogen atom leaves, and the pentyl group is connected to thiophene, which is also 2-n-pentyl thiophene. This way, low temperature operation is required to maintain the activity of lithium compounds, and the environment without water and oxygen is indispensable to prevent the hydrolysis or oxidation of lithium compounds.

There is also a method of metal catalysis. For example, taking a palladium catalyst as an example, thiophene and n-pentene are coupled and reacted with the help of suitable ligands and bases to form the target product. This catalytic reaction has good selectivity and can reduce the formation of impurities. However, the cost of catalysts is high, and the reaction conditions need to be precisely regulated, such as temperature and catalyst dosage, in order to

All kinds of synthesis methods have their own advantages and disadvantages. In practical application, the purpose of synthesis can be achieved only when careful choices are made according to many factors such as the availability of raw materials, cost considerations, and product purity requirements.

What is the price range of 2-n-Pentylthiophene in the market?

2-N-pentylthiophene is in the market, and its price range is difficult to determine. This causes its price to fluctuate due to multiple reasons. First, the situation of supply and demand is the main reason. If there are many applicants and few suppliers, the price will necessarily increase; conversely, if the supply exceeds the demand, the price may fall.

Furthermore, its manufacturing cost is also related to the price. The price of raw materials, production technology and energy consumption will all affect its cost. If the price of raw materials rises, or the cost of production technology needs to be improved, the price will also be higher.

In addition, competition in the market is also the key. Businesses compete for the market, or adjust prices due to competition for customers. Those with high productivity and low cost may be able to expand the market at a low price.

In addition, geopolitical and trade policies also have an impact. Changes in trade barriers and tariffs can cause their prices to fluctuate.

Based on today's market conditions, the price of 2-n-pentylthiophene may range from a few to a few tens of yuan per gram. However, this is only a rough estimate, and the actual price should be determined based on real-time market conditions and details such as purchase quantity and quality. To know the exact price, it is recommended to consult the chemical raw material supplier or check the quotation of the relevant trading platform to get a close price.
