Fig.1 Structures of Crystal violet and Leuco-crystal violet Crystal violet (CV), also known as gentian violet, commonly known as methylis violaceum, its formula is C25H30ClN3, and its metabolite is Leuco crystal violet (LCV), their structures are shown in Fig.1, they are both triaryl methane chemical, because CV can kill some of the superficial fungi, it's often used as an anti-fungal additives in the production of feed to improve the health and survival of animal.
Among them, takes different structure of purification column according to the different needs.

Ionic liquids are promising catalysts for the production of biodiesel, which meet the requirements of green chemistry showing attractive prospect for industrialization[13].
One of the more popular methods in the literature for making biodiesel in ionic liquids is to use acid-catalyzed chemistry based on an intrinsically acidic ionic liquid.
The structures of the catalysts were experimentally characterized and theoretically analyzed, and catalytic activities and reusability of the catalysts were evaluated through an esterification reaction between oleic acid and methanol.
Conclusion and prospect Biodiesel is a clean-burning diesel fuel with a chemical structure of fatty acid alkyl esters.

Introduction In recent years, Graph has been widely used in many areas of computer, telecommunications engineering, chemistry etc.
Due to the complicated data structure of graph, where any two nodes may be relevant, there are no physical locations in the storage area to represent the relationships of the nodes, namely it has no sequential storage structure.
Common Storage Structure of Graph Graph.

These structures demonstrated the enhanced optical absorption and photoresponse [2].
While some findings are revealed for Si/Ge-NCs structures without SiOx layer [5], there is still lack of information and model for carrier transport in the Si/SiOx structures with high-density Ge-NCs.
Experimental The Si/SiOx/Ge-NCs structures investigated were processed as follows [6].
The structures under discussion have a valence band offset of about 0.7 eV [16].

The shapes and structures can be controlled by changing the reactants and experimental conditions.
The shapes and structures were controlled by changing the reactants and experimental conditions.
The structures and luminescent properties of ZnO hexagonal rods array were characterized.
The crystal structure was analyzed using XRD with Cu Kα radiation.
The main peaks can be indexed to the hexagonal phase of zinc oxide (wurtzite structure, space group P63mc).

The synthesis of LIFePO4 solvent hot when different solvents on product morphology and the influence of the structure is discussed To glycol as solvent synthesis of LIFePO4 homogeneously flake structure, it has small size and thickness thin characteristics, this structure shorten the distance the spread of lithium ion, be helpful for electrochemical performance improvement.
At present, reports in the literature of LiFePO4 synthesis method used for is still solid chemistry synthesis methods of classic, such as solid phase method, hydrothermal synthesis, carbon hot reduction method and sol-gel, recently reported that the total precipitation, microwave method [1-4].
Solvent heat method The heat was in ethanol solvent respectively, glycol and glycerin/water for was used to synthesize peridot structure of LIFePO4.
Crystal structure of the product, particle morphology and surface microstructure were discussed in detail the solvent hot synthesis LIFePO4 different solvents on product when the influence of the structure and morphology.
Through the time single factor experiment results, we put forward a reasonable classification structure formation mechanism assembly figure.

Introduction For the last 30 years, studies on Quantitative Structure Activity Relationships (QSAR) have been unquestionably ranked as among the most important in modern chemistry and biochemistry[1].
If we could elucidate in detail how these properties are determined by structure we were able to predict such properties simply from the molecular structure[2].
The common skeleton structure of N-dichloroacetyl oxazolidine was given in Figure 1.
All studied compounds structures were list in Table I .
Figure 1 General structure of N-dichloroacetyl oxazolidine derivatives.

In the world, there is more research on the KGM molecular structure, however its exact molecular structure has not been determined, that is not exact molecular structure of KGM in today, it can generate a variety of derivatives with other organic matter, such as acetylene glucomannan, methyl alcohol glucomannan, propylene glucomannan.
In addition to glucose and mannose residues, there is also acetyl, its molecular structure schematic diagram of KGM is shown in Figure 1.
