Abstract: A process for preparing PPE microspore dispersion includes steps of: dissolving a high-molecular polyphenylene ether in a first solvent at 45-110° C. to form a dissolution liquid; adding processing aids and well mixing the dissolution liquid into a dispersed phase; cooling the dissolution liquid to 42-80° C., and adding a second solvent to generate PPE microspores via PPE to wrap around the processing aids; cooling the dissolution liquid to 0-40° C. to obtain PPE microspore dispersions for use in application for impregnation processes performed below 40° C., thereby high-temperature impregnation equipment are no longer needed, and copper clad laminates made of using the PPE microspore dispersion enjoy excellent physical properties including high Tg, low Dk, low Df and high copper foil's peel strength.

Abstract: A process for producing polyphenylene ether involves to keep a combustible solvent at a gaseous concentration below the minimums of explosion, to keep oxygen gas supplied at a gaseous concentration below the limiting oxygen concentration (LOC) of the solvent, and to make use of a reactor having a rotary-sealed mixer sealed with magnetic rotary feedthroughs to prevent static electricity generated, and then to improve safety and yield thereof.

Abstract: A method is disclosed for use in reducing chemical oxygen demand (COD) of alkaline wastewater generated from an aldol condensation reaction during a process for preparing 2-ethylhexanol, which teaches both high-boiling-point aldol mixtures and low-boiling-point aldol mixtures are used to serve as an extractant for reducing COD in the wastewater, and further to perform a stripping treatment, thereby a removal rate of COD in the wastewater of 89-93% is then achieved.
