Introduction | Dimeric p-xylene (also known as: Palilin), as a new type of polymer functional material, is a kind of polymer with p-xylene as the skeleton The general term, the benzene ring or methylene of this polymer can be hydrogen, or it can contain various substitution groups. |
use | dimethylene is a useful research chemical. is a protective polymer material, which can be deposited under vacuum. The penetrating power of Parylene N molecules can make it form a high-quality protective layer without pinholes inside, at the bottom and around the element. It can be used in microelectronics, semiconductors, printed circuit plate biosensors, cultural relics protection and other fields. |
preparation | 45g of potassium carbonate, 58g of potassium fluoride and 1.2g of benzyl triethylammonium chloride were added to a 1L three-mouth flask and dissolved in 500mL of water. 61.8g (2-chloro-4-chloromethylbenzyl) trimethylsilane was dissolved in 100 mL toluene solution, and heated to 80~85 ℃ for 3h under intense stirring. Cool, add 300mL of water to dilute, and separate the organic phase. The water layer was extracted with 300mL toluene. The organic phase was combined and concentrated. The crude product was recrystallized with 100mL ethanol to obtain 32g of white powder C- type dimeric parylene with a yield of 88%. 48g of sodium hydroxide, 168g of sodium fluoride, 2.3g of benzyl triethylammonium chloride were added to the three-mouth flask and dissolved in 800mL of water, and then 213g of (p-chloromethyl benzyl) trimethylsilane and 1000mL of toluene were added. Under intense stirring, the temperature is raised to 80 ℃ for 2 hours. Cooling, separation. The aqueous phase is extracted with toluene. Concentrate and recrystallize the crude product with ethanol to obtain 96g of white powder n-type dimeric p-xylene with a yield of 92% |
