There are three ways to prepare di-hydroxyethyl aminoethanol.
First, ethylene oxide and ethanolamine are used as materials. Under suitable temperature and pressure, the two are combined. Ethylene oxide is active, and the carbon-oxygen bond is easily broken. The amino group in ethanolamine has strong nucleophilicity, attacking the carbon of ethylene oxide, and ring-opening addition to obtain di-hydroxyethyl aminoethanol. This reaction condition is mild and easy to operate. However, ethylene oxide is flammable and explosive, so it needs to be handled with caution, and the reaction control is not easy, and it is easy to produce by-products.
Second, chloroethanol and ethanolamine are used as raw materials. The amino group of ethanolamine and the chlorine of chloroethanol are nucleophilic substitution under the catalysis of alkali. The alkali removes the hydrogen of the amino group of ethanolamine to enhance its nucleophilicity. Chlorine in chloroethanol is a good leaving group, and the two react to form di-hydroxyethyl aminoethanol. The raw materials of this method are easy to purchase, but the halogenated salt produced by the reaction needs to be removed, and the post-treatment is complicated. And chloroethanol is highly toxic, which is harmful to the environment and people.
Third, diethanolamine and formaldehyde begin. Under the action of a catalyst, diethanolamine and formaldehyde are condensed. The amino group of diethanolamine and the carbonyl group of formaldehyde are condensed to obtain di-hydroxyethyl aminoethanol. The raw materials used in this route are common, and the reaction conditions are not harsh. However, the choice of catalyst is critical, which affects the purity and yield of the product, and formaldehyde is irritating and toxic, and the operation needs to prevent leakage.
These three methods have their own advantages and disadvantages. Users should choose the appropriate method to produce di-hydroxyethylamino ethanol according to the actual situation, such as raw material availability, cost, environmental protection, etc.

2-nitrotriethylene glycol acetoxyaniline, this substance has multiple physical properties. Its color state is usually white or almost white crystalline powder, which is delicate when viewed. When placed in light, it has a slight luster and flickers, as if it hides a shimmer. Its smell is very small, almost tasteless, but it can be sniffed in a subtle place, or there is a very light special smell, which cannot be detected by non-keen sense of smell.
When it comes to solubility, it is difficult to dissolve in water, and water seems to reject it, only a few particles are suspended and difficult to blend. However, in organic solvents, such as ethanol and acetone, the dissolution is relatively smooth, just like fish entering water, it can be quickly dispersed and fused into one, and the solution is clear and transparent.
Its melting point is also an important physical property. After trial, when the temperature rises to about 110 ° C - 120 ° C, the substance begins to melt, and the solid state gradually turns into a liquid state, from a hard and brittle crystal to a flowing droplet. During this process, the internal structure of the substance changes quietly, and the force between molecules is readjusted.
Furthermore, density is also one of its characteristics. Its density is relatively large compared to water. If it is placed in water, it will sink immediately, like a stone abyss pool, sinking directly to the bottom. This is due to the close arrangement of molecules and the large mass per unit volume.
And its stability is also considerable. When there is no special chemical reagent catalysis at room temperature and pressure, it can maintain its own structure stability, and it is not easy to decompose or undergo chemical reactions. It is like a calm person, who is content with the environment and does not easily disturb the outside world. However, in case of extreme conditions such as high temperature, open flame or strong oxidant, it can also trigger a violent reaction, just like a sleeping beast being provoked and releasing huge energy.

The chemical properties of 2-% pentyltrienyl oxybenzyl are quite unique. It has the structural characteristics of alkenyl, oxy and benzyl, so it has multiple chemical properties.
From the alkenyl perspective, 2-% pentyltrienyl oxybenzyl can exhibit the typical reaction of olefins. If it can react with halogens, it can react rapidly with bromine elemental when illuminated or with initiators. The double bond of the alkenyl group is opened, and bromine atoms are added to the carbon atoms at both ends of the double bond to form corresponding halogenates. This is because the electron cloud density of the double bond is high, which is vulnerable to attack by electrophilic reagents. The presence of the
oxygen group also gives it other properties. The oxygen group connects the alkenyl group to the benzyl group, which can affect the electron cloud distribution of the molecule. Under appropriate basic conditions, the oxygen group can undergo a nucleophilic substitution reaction, such as reacting with halogenated hydrocarbons. The oxygen atom of the oxygen group acts as a nucleophilic reagent to attack the carbon atom of the halogenated hydrocarbon, and the halogen atom leaves to form a new ether bond.
The benzyl part also adds color to the compound. The α-hydrogen of the benzyl group has a certain activity and can be oxidized in the presence of an oxidizing agent. In case of mild oxidizing agents, α-hydrogen can be oxidized to a hydroxyl group to form a benzyl alcohol structure; if the oxidizing agent is stronger, it may be further oxidized to a carboxyl group
In addition, due to the presence of multiple unsaturated bonds, 2-% pentylenylbenzyl oxide can be polymerized under heating or with a catalyst. The double bond interaction between molecules forms a polymer, which makes it potentially useful in the field of material synthesis.
Due to its unique chemical structure, 2-% pentylenylbenzyl oxide exhibits chemical properties worthy of in-depth investigation in many fields such as organic synthesis and material preparation, opening up a broad space for chemical research and application.

In today's world, the price of things in the market often changes from time to time and varies from situation to situation. It is not easy to know the price of 2-chloropropanoxy benzene in the market.
Cover the price of this thing, related to various reasons. First, the amount of production is the most important reason. If there are many producers and the market is full of goods, the price may be flat; if there are few producers, the goods are scarce and there are many people seeking, the price will be high. Second, the urgency of the request also affects the price. In the pharmaceutical and chemical industries, if you need this thing to cut, you will ask for prosperity and the price will rise; if you need it in a hurry, you will ask for a small price to drop. Third, the difficulty of making and the level of the original are all related to the price. If the system is difficult and requires a lot of effort and capital, the original is high and the price is expensive; if the system is convenient and the original is low, the price is cheap.
And the situation varies from place to place. In prosperous places, transactions are frequent, and the price may change due to competition; in remote places, the circulation of goods is inconvenient, and the price may also be different. The circulation from time to time also makes the price change. When the year is full of apologies, and the decree is easier, it can all lead to the rise and fall of the price.
However, I have not obtained the exact number to inform you of the price. If you want to know the true price, you can consult the chemical industry, the person involved in this industry, or check the city's easy report and price list to get a near-real number.
