What are the physical properties of 4- (trifluoromethyl) cinnamic acid?
(Sanxiang Jiadi) myristic acid, with various physical properties. It is a white to yellowish white hard solid, waxy and shiny. At room temperature, the properties are stable, odorless, and have a slightly specific aroma.
Looking at its melting point, it is about 54 to 58 degrees Celsius. This temperature causes it to gradually melt from the solid state. The boiling point is quite high, and it vaporizes when it is 250 to 260 degrees Celsius (13.3 kPa). The density is relatively fixed, about 0.8439 grams/cubic centimeter (80 degrees Celsius), and its mass per unit volume can be known.
Myristic acid is slightly soluble in cold water, slightly soluble in hot water, but easily soluble in organic solvents such as ethanol, ether, and chloroform. This difference in solubility is related to the polarity of the solvent.
Because of its long-chain alkyl structure, it has a certain hydrophobicity, so it does not dissolve well in water. The structural characteristics of organic solvents are conducive to the dispersion of myritic acid molecules and good solubility.
In addition, myritic acid has the common characteristics of oleic substances, and can saponify with alkalis to generate corresponding soaps and glycerol. This reaction has applications in many aspects of industry and life, such as the soap industry, which can be used to produce cleaning products such as soap.
Its physical properties have far-reaching influence in various fields. In the cosmetics industry, it can be used as an oily raw material, leveraging its solid-state properties and solubility to formulate product texture and stability. In the food industry, it can be used as an additive to improve food taste and quality. In the chemical industry, it participates in many chemical reactions and is the basic raw material for the synthesis of complex compounds.
What are the chemical properties of 4- (trifluoromethyl) cinnamic acid?
(Sanxiang Grade A) Calcium lactate is peaceful in nature and has many wonders. Its taste is light and easily soluble, and it can gradually dissipate in water. It has no pungent smell or strange odor. It is like a mild and elegant person, and it melts quietly.
Looking at its chemistry, it is an organic calcium salt and the like, and the stability is quite good. In ordinary warm and dry environments, it can be safely handled, and it is not easy to deteriorate and rot. And in the domain of moderate acid and alkali, it can maintain its inherent state, and it is not easy to change violently with common weak acids and alkalis.
When talking about the nature of the reaction, when encountering strong acid, it will be moved. Just like a humble gentleman who encounters a tyrannical trend, he will also show a different style. It can react with strong acids to replace, release the root of lactic acid, and form new compounds. However, this reaction is not a rapid and violent state, but a gradual one, such as a trickle piercing a stone and slowly dissolving.
And because of its calcium content, it has an extraordinary effect on the human body. After the human body ingests it, it can slowly be absorbed by the body to supplement the calcium it needs. Its absorption by the human body is like a spring rain moisturizing the body, quietly but nourishing, unlike other calcium salts that are difficult to ingest, so it is favored. It is often used in the way of health care by doctors to strengthen the tendons and bones, which is beneficial to the bodies of women and children, old and young. It is actually a peaceful and useful good thing.
What are the synthesis methods of 4- (trifluoromethyl) cinnamic acid?
To prepare tetra- (triethyl) pyruvate, there are three methods.
One is the method of condensation. Take appropriate esters, such as ethyl acetate and an ester containing triethyl methyl, under the action of alkaline catalysts such as sodium alcohol, Claisen condensation reaction is carried out. In this process, the basic reagent prompts the departure of α-hydrogen from the ester molecule to generate carbonic anions, which undergo nucleophilic addition-elimination reaction with another ester molecule, and then obtain beta-ketoic acid containing tetra- (triethyl) structure. After acidic hydrolysis and decarboxylation, the target product tetra- (triethyl) pyruvate can be obtained. The steps of this method are slightly complicated, but the raw materials are easier to obtain, and the reaction conditions are relatively mild, so it is quite commonly used in organic synthesis.
The second is the Grignard reagent method. First, halogenated hydrocarbons containing triethyl methyl are prepared, and magnesium chips are reacted in anhydrous ether and other inert solvents to make Grignard reagents. Then the Grignard reagent is reacted with pyruvate esters. The carbon-magnesium bond in the Grignard reagent has strong nucleophilic properties, which can carry out nucleophilic addition to ester carbonyl to form intermediate products. After hydrolysis, tetra- (triethyl) pyruvate can be obtained. This method has high reactivity and good yield. The Grignard reagent is extremely sensitive to water and air, and the preparation and reaction operation need to be carried out under strict anhydrous and anaerobic conditions.
The third is the enolization method. The carbonyl compound containing triethyl methyl is used as the starting material and enolized under the action of alkali to form enol negative ions. This negative ion undergoes nucleophilic substitution reaction with pyruvate derivatives to construct the carbon skeleton of the target product. After acidification and other treatments, tetra- (triethyl) pyruvate acid is obtained. This method has high selectivity and can effectively avoid unnecessary side reactions. However, the selection of starting materials and the control of reaction conditions are strict.
What is the price range of 4- (trifluoromethyl) cinnamic acid in the market?
In today's world, in the market, the price of (triallyl) maleic acid is indeterminate. This is a product of fine chemicals, and its price often changes due to multiple reasons.
Looking at the market conditions, first, the price of raw materials has the greatest impact on the price of (triallyl) maleic acid. If the production of raw materials is unfavorable every day, or the production area changes, resulting in a small supply, the price will rise. On the contrary, if the raw materials are abundant and the supply exceeds demand, the price may drop.
Second, the difficulty and refinement of the process are also related to its price. If the method of making this (triallyl) maleic acid is complicated and requires a lot of manpower and material resources, and consumes a huge amount of energy, its price will be high. However, if the process is innovated, the efficiency is greatly increased, and the money and effort are saved, the price may drop.
Third, market demand is also the key. If various industries are eager for (triallyl) maleic acid, such as medicine and materials, it is widely used and urgent, and the supply is in short supply, the price will rise. On the contrary, if there is a lack of demand, the supply will exceed the demand, and the price will decline.
To sum up the above reasons, the price of (triallyl) maleic acid in today's market is about hundreds to thousands of yuan per kilogram. The actual price often moves with the change of the market, and it cannot be generalized. Merchants want to know the exact price, and they must always observe the state of the market and the change of feelings, so that they can know the clues of the price.
