2% 2C3 -dioxane is an organic compound with the following physical properties:
First, it is a colorless and transparent liquid under normal conditions, just like clear water, flickering and shiny under light. This appearance characteristic is in many reaction systems, which can be clearly observed by the naked eye and is easy to distinguish.
Second, smell, it has a weak ether smell, the smell is not strong and pungent, but it also has a unique smell, which can be slightly distinguished by the sense of smell. In the actual operating environment, this odor characteristic may be one of the clues to judge its existence.
Third, when it comes to the boiling point, it is about 50-52 ° C, and the boiling point is relatively low. This property makes it easier to change from liquid to gaseous under moderate heating conditions. In experimental operations such as distillation and separation and industrial processes, it can be effectively separated from the mixture according to the difference in boiling point.
Fourth, the apparent density is about 1.13 g/cm ³, which is slightly heavier than water. When mixed with liquids with different densities such as water, there will be stratification due to density differences. With this property, separation and other means can be used for separation operations.
Fifth, it is related to solubility. It can be miscible with various organic solvents such as water, ethanol, and ether. Such good solubility makes it an excellent solvent in many organic synthesis reactions, assisting the uniform dispersion of the reactants, promoting the smooth progress of the reaction, and greatly expanding its application in the field of chemistry.

2% 2C3 -dihydroxypropionaldehyde, also known as glyceraldehyde, is an important organic compound. It has unique chemical properties and plays a key role in many chemical reactions and biological processes.
This compound contains an aldehyde group and two hydroxyl groups. Due to the presence of hydroxyl groups, it has a certain hydrophilicity and can form hydrogen bonds with water, resulting in a certain solubility in water. And the hydroxyl group is an active functional group, which can participate in many chemical reactions, such as esterification reactions, and can react with carboxylic acids under suitable conditions to form ester compounds. This reaction is used in the field of organic synthesis to prepare esters with specific structures, and is of great significance in the synthesis of fragrances and drugs.
The presence of aldehyde groups endows glyceraldehyde with reductive properties, which can react with Torun reagent, Feilin reagent, etc. This property is often used for qualitative and quantitative analysis of aldehyde groups. In vivo, glyceraldehyde is an important intermediate product of sugar metabolism and participates in key metabolic pathways such as glycolysis. During glycolysis, glyceraldehyde-3-phosphate is gradually converted into pyruvate through a series of enzymatic reactions to provide energy for cells.
In addition, there are enantiomers of glyceraldehyde, namely D-glyceraldehyde and L-glyceraldehyde. The physiological activities and metabolic pathways of these two isomers in vivo may be different. Organisms often have the ability to selectively recognize and utilize compounds of specific configurations. For example, in some enzyme-catalyzed reactions, only glyceraldehyde of specific configurations can participate in the reaction as a substrate, which is crucial to maintaining the orderly progress of metabolic processes in organisms.
Its chemical properties, hydrophilicity, reductivity and stereoisomerism make it important in both organic chemistry and biochemistry, and it is of great significance for understanding many chemical and biological processes.

2% 2C3-dihydroxyacetone, which can be prepared by catalytic oxidation of glycerol. The method is as follows:
Select refined glycerol, place it in a special reactor, and pre-fill the kettle with an appropriate amount of specific catalyst. This catalyst is obtained after many trials and has high activity and selectivity. Pass oxygen into the kettle, and control the temperature in a suitable range, about [X] degrees Celsius. After repeated debugging, this temperature can make the reaction efficient and less side reactions. Adjust the pressure to an appropriate value, about [X] kPa, to create an environment conducive to the reaction.
During the reaction, closely observe and measure each parameter with precise instruments. Under the action of the catalyst, the glycerol molecule gradually interacts with the oxygen molecule, and the hydroxyl group is gradually oxidized and converted into the dihydroxyacetone molecule. After some time, the reaction is near the end, and the product is precipitated from the reaction system by delicate separation. First, the distillation method is used, according to the boiling point of each component, and the preliminary fractionation is used to obtain the mixed liquid containing the product. Then the chromatography method is used to further purify the high purity 2% 2C3-dihydroxyacetone by the difference of the distribution coefficients of different substances in the stationary phase and the mobile phase.
Preparation of this substance requires fine operation and strict management conditions to obtain the ideal yield and purity, which can be used for subsequent applications in various fields for high-quality raw materials.

The price range of 2% 2C3-dihydro nematic crystals on the market is difficult to say exactly. This is because the price of dihydro nematic crystals is influenced by various factors.
First, quality is important. If it has high purity, few impurities, and meets specific high-end use standards, the price will be high; on the contrary, if the quality is poor, the price will be slightly lower.
Second, the trend of supply and demand is also critical. When market demand exceeds supply, such as a surge in demand for dihydro nematic crystals in a certain field, and the output is limited, the price will rise; if supply exceeds demand, the price may drop.
Third, the origin and source have a great impact. Different origins, due to the amount of resources, the quality of craftsmanship, the cost is different, resulting in different prices. Importers, or due to tariffs, transportation costs, etc., the price is different from that of local producers.
Fourth, the market competition situation is related to the price. If there are many market participants and the competition is fierce, merchants may adjust the price to compete for a share.
According to common market conditions, 2% 2C3-dihydro nematic crystal of ordinary quality, the price per unit may be between tens and hundreds of currency units; while high purity and special specifications may reach thousands of currency units per unit. However, this is only a rough estimate, and the actual price must be carefully investigated according to the current market conditions.
