Polyethylene glycol is also called PEG, PEG "400" mean that the average molecular weight of the specific PEG is 400.Is used as an inactive ingredient in the pharmaceutical industry as a solvent, plasticizer, surfactant, ointment and suppository base, and tablet and capsule lubricant.
Absorption treatment of trichloroethylene waste gas
Polyethylene glycol has different surface activities depending on its degree of polymerization, and can change the surface properties of aqueous solutions to varying degrees. It has been extensively studied in the treatment of exhaust gas absorption, especially in the treatment of toluene waste gas, which is remarkable. effect. Pingping Plus O-25 is a fatty alcohol polyoxyethylene ether with good hydrophilic properties.
Green chemistry concept in polyethylene glycol applications
The response of PEG will continue to attract further exploration of PEG as a solvent.And the support of the catalyst, and the grafting functionalization with the ionic liquid with the advantages of stable and almost no volatility; and the application in combination with microwave technology and biochemistry, which helps to improve the yield of the organic reaction and optimize Reaction time; while PEG as the medium of reaction, it will be more inclined to recycle some expensive metal catalysts。
In the cement industry, a large amount of energy is consumed in the grinding of raw materials and their clinker. Grinding process, cement particle surface free charge density increases, the solid surface free energy increase, coupled with the collision between particles
Chinese Youth’s Day is on May 4th, it is to in honor of the students’movement in the year of 1919, at that time, the government made a failing diplomacy in Paris, which resulted in signing the treaty of losing the land.
