What is the chemical structure of (12E) -3,7:6,10-didehydrated-2,4,5,12,13-pentadeoxy-8,9,11-tri-O- [ (1,1-dimethylethyl) dimethylsilyl] -13-iodine-L-arabic-D-allotridecan-12-enoic acid methyl ester?

"Tiangong Kaiwu" says: "All things are born from vitality. To know the chemical structure of dimethyl oxalate, you need to investigate its root cause and analyze its composition."

Dimethyl oxalate is an organic compound. Its molecules are composed of carbon, hydrogen and oxygen. Structurally, it contains two methyl formate groups. It can be regarded as the product of the esterification reaction between oxalic acid and methanol.

Oxalic acid has two carboxyl groups (-COOH), and methanol has a hydroxyl group (-OH). When the two react, the hydroxyl group in the carboxyl group combines with the hydrogen atom of the hydroxyl group in the methanol to form water, and the remaining part is connected to form dimethyl oxalate. In its chemical structure, two methyl ester groups (-COOCH) are connected by a carbon atom, which is also connected to two other oxygen atoms, and the whole takes on a specific spatial configuration. This structure endows dimethyl oxalate with unique chemical properties, enabling it to participate in many organic reactions and is widely used in the chemical industry, such as in the synthesis of other organic compounds, such as certain pharmaceutical intermediates, fragrances, etc. Understanding its structure is of great significance for controlling related chemical reactions and industrial applications. As mentioned in "Tiangong Kaiyi", knowing the physical properties can make good use of it.

What are the physical properties of (12E) -3,7:6,10-didehydrated-2,4,5,12,13-pentadeoxy-8,9,11-tri-O- [ (1,1-dimethylethyl) dimethylsilyl] -13-iodine-L-arabic-D-allotridecan-12-enoic acid methyl ester?

I dare to ask you, this is a question about chemical substances. (12E) - 3,7:6,10 - diyne-diol - 2,4,5,12,13 - pentyne-oxygen - 8,9,11 - tri - O - [ (1,1 - diethoxyethoxy) diethoxysilyl] - 13 - guanidine - L - arabinose - D - allotridecanoic acid - 12 - ethyl oleate.

The physical properties of this ethyl oleate are quite important. Looking at its appearance, at room temperature, it is mostly a colorless to light yellow oily liquid, with a warm texture and a smooth touch. It has a unique odor, a weak and pleasant grease smell, and a non-pungent and strong smell.

When it comes to solubility, this substance is insoluble in water. Due to the characteristics of its molecular structure, it is quite different from the polarity of water and is difficult to blend. However, among many organic solvents, such as ethanol, ether, chloroform, etc., it has good solubility and can be miscible with it.

Furthermore, its boiling point is about 207-208 ° C. At this temperature, ethyl oleate will be converted from liquid to gas. The melting point is around -32 ° C. Below this temperature, it will condense from liquid to solid.

In addition, the density of ethyl oleate is less than that of water, about 0.87g/cm ³. If it is placed in one place with water, it can be seen floating on the water surface.

These are common physical properties of ethyl oleate. In many fields such as chemical industry, medicine, food, etc., its properties play a key role in applications.

To prepare methyl oleate, follow the ancient method. The method is as follows:
Prepare raw materials to obtain oleic acid and methanol, which are the foundation for making this substance. Take an appropriate amount of concentrated sulfuric acid and use it as a catalyst to promote the reaction.
In a clean reactor, add oleic acid and methanol in a certain ratio. Generally speaking, the molar ratio of the two should be 1:3 to 1:6, so that the reaction can be more sufficient. Next, slowly add concentrated sulfuric acid, and the dosage is about 0.5% - 2% of the total mass of the reactants. Do not overdo it to avoid side reactions.
The reactor is sealed and heated in a water bath or an oil bath to maintain the temperature in the kettle between 60 and 80 degrees Celsius. This temperature range can not only ensure the reaction rate, but also avoid excessive volatilization of the reactants. When heating, it is necessary to continuously stir to make the reactants fully mixed and the reaction is uniform.
After several hours of reaction, when the acid value of the reaction solution drops to a certain extent, the reaction can be regarded as roughly completed. At this time, the product is mixed with sulfuric acid, unreacted oleic acid and methanol, so it needs to be purified.
First pour the reaction solution into the separation funnel, let it stand and layer, and discard the lower acid. Wash the upper organic phase with an appropriate amount of saturated sodium carbonate solution until no bubbles are formed to remove residual sulfuric acid and unreacted oleic acid. After that, wash the organic phase with distilled water several times until the washing liquid is neutral to remove residual sodium carbonate.
After washing, transfer the organic phase to a distillation flask, and evaporate the residual methanol and other low boiling point impurities by vacuum distillation. The final pure liquid is methyl oleate.
According to this ancient method, careful operation can be obtained to obtain methyl oleate.

Alas, the question here is about (12E) - 3,7:6,10 - diethyl ether - 2,4,5,12,13 - phosphorus pentoxide - 8,9,11 - tris - O - [ (1,1 - diethylethyl) diethylbenzyl] - 13 - iodine - L - arabinose - D - allotridecanoic acid - 12 - fatty acid ethyl ester. These chemical substances have a wide range of uses.

First, diethyl ether, which is often used as an organic solvent in the chemical industry. Due to its good solubility, many organic compounds can be dissolved in it. In the organic synthesis reaction, it can provide a suitable environment for the reaction, and help the reactants to better contact and react. And because of its good volatility, it is easier to separate and remove after the reaction.

Phosphorus pentoxide has many uses. In the chemical industry, it is often used as a desiccant because of its strong water absorption, which can efficiently remove moisture from gases or liquids and keep the environment dry. In the pharmaceutical field, it is also used. It can participate in some drug synthesis reactions and is a key raw material or catalyst.

Say three-O- [ (1,1-diethylethyl) diethylbenzyl], such compounds with complex organic structures may have unique uses in the field of materials science. Or it can be used to prepare polymer materials with special properties, giving materials such as unique optical and electrical properties.

L-arabinose is used in the food industry. It has a certain sweetness, but it is difficult to be absorbed by the human body. It can be used as a low-calorie sweetener and is suitable for adding to foods of people who need to control sugar, such as diabetics. And it may have a regulatory effect on intestinal flora, which is beneficial to human intestinal health.

D-allotridecanoic acid and 12-fatty acid ethyl ester are common in the field of oleochemical industry. Can be used to prepare various oils, lubricants, etc. Fatty acid ethyl ester can be used as a plasticizer raw material to enhance the flexibility and plasticity of plastic products. And tridecanoic acid or participate in the synthesis of special oils to meet special industrial needs.

In short, these chemicals have important applications in chemical, pharmaceutical, food, materials and other fields, promoting the development of various industries.
