Phenol,compound with 2,3,4,6,7,8,9,10-octahydropyrimido [1,2-a]azepine - Design, synthesis and properties of low viscosity ionic liquids of phenol salt
from VIP Journal Professional Edition

Abstract:
as a new type of "green solvent", ionic liquids are widely used in organic synthesis, industrial catalysis, gas separation and other fields. However, due to the high viscosity and poor transport performance of most ionic liquids, their application in industry is limited to a certain extent. How to design and synthesize low viscosity ionic liquids has become a hot topic in the field of ionic liquids. Based on the above problems, the main contents of this paper are as follows: four kinds of low viscosity phenol salt ionic liquids were designed and synthesized, the structure of ionic liquid was determined by IR and elemental analysis. Its density, viscosity, refractive index and conductivity were measured in detail. The results show that the density, viscosity and refractive index of the ionic liquid decrease with the increase of temperature in the temperature range of 298.15 to 343.15K, while the conductivity increases exponentially with the increase of temperature.

Abstract:
The invention discloses a synthesis method of tetraphenylphosphine phenate, which comprises the following steps: under the action of a catalyst, triphenylphosphine and bromobenzene are added to the reaction solvent for reaction, and after the reaction is finished, tetraphenylphosphine bromide was obtained by filtration, recrystallization and vacuum drying. Tetraphenylphosphine bromide, phenol and deionized water were added to the reaction kettle, heated to 2025 ℃, and sodium hydroxide solution was quickly added to adjust the pH of the mixed solution to 9.511.0, after completion of the reaction, isobutanol was added and stirred evenly to separate the organic phase. The organic phase was washed three times with three times of deionized water, and the isobutanol was distilled off under vacuum at 4550 ℃ and dried under vacuum at 80100 ℃. In the synthetic route of the phenylphosphine phenol salt of the invention, triphenylphosphine, bromobenzene and phenol are used as production raw materials, the raw materials are easily available, and the production cost is low.
