Organic Solvent

DXC have the following characteristics: 1, the evaporation rate is moderate, and n-butyl acetate rather, slightly slower than MIBK, odor small; 2, for a variety of natural resins, synthetic resins and nitrocellulose, cellulose ether solvent; 3, used in coatings, inks, adhesives, and other industries in a solvent; can replace or partially replace butyl acetate, MIBK, and other products; 4, electronic, metal processing industry and then used as a cleaning agent.

Diisopropyl biphenyl (DIPB) is a colorless and odorless transparent liquid. It is a new type of high boiling point and environment-friendly solvent. It has the characteristics of colorless and odorless, low viscosity, high boiling point and difficult volatilization. Therefore, it is not counted as VOC (volatile organic compound), and has the characteristics of good wettability of pigments and fillers, increasing compatibility and so on. It is widely used in the preparation of carbon free copy paper capsule, capacitor insulating oil and high temperature heat transfer oil. It can replace expensive diisopropyl naphthalene and diaryl ethane.

Trioctyl citrate is a widely used non-toxic plasticizer. It has excellent cold resistance, light resistance and water resistance. It can be used as plasticizer for polyethylene, polyvinyl chloride and various cellulose resins. It has the advantages of good compatibility, high plasticization efficiency, non toxicity and low volatility. It has excellent rotatory light resistance and water resistance; It can also be used in food packaging, medical and health products and children's toys, and can replace phthalate plasticizers with carcinogenic effect; In addition, it can also be used as defoamer for protein solutions. Trioctyl citrate is usually obtained by esterification of citric acid and industrial octanol (2-ethylhexanol) under the action of catalyst and water carrying agent, and then refined to industrial products. Sulfuric acid under vacuum is often used as catalyst in classical processes, and non sulfuric acid catalyst under atmospheric pressure is mostly used in new processes. The commonly used non acid catalysts are titanate and organotin. The water carrying agent here is usually industrial octanol itself. The reaction temperature is generally about 220 ℃.

The electrolytes of chemical power supply include aqueous electrolyte and non-aqueous electrolyte. In addition to the factors of electrode material, the advantages and disadvantages of lithium-ion battery are closely related to the properties of electrolyte. Due to the good temperature stability of electrolyte and wide electrochemical window, the working voltage of lithium-ion battery (usually about 4V) is more than twice that of battery using aqueous electrolyte (generally no more than 2V), Therefore, lithium-ion batteries have the properties of high voltage and high specific energy. At the same time, lithium-ion batteries also have the important deficiency of dry non-aqueous electrolyte. The conductivity of nonaqueous electrolyte is less than one tenth of that of aqueous electrolyte, which limits the high rate charge discharge performance of lithium-ion battery; The high technical content and price of electrolyte lead to the high cost of lithium-ion battery; The high tenderness of organic liquid electrolyte has become an insurmountable safety hazard of liquid lithium-ion battery. Therefore, in order to overcome its shortcomings on the basis of ensuring the advantages of lithium-ion battery, the electrolyte system of lithium-ion battery must have some special properties.
