On November 19, 2003, Qiu, Yong; Wang, Liduo; Li, Yinkui published a patent.Quality Control of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene The title of the patent was Preparation of polyphenylenevinylene through etherification, halomethylation and polymerization. And the patent contained the following:
A polyphenylenevinylene is prepared by the following steps: etherifying hydroquinone or 4-methoxyphenol in water or alc.; halomethylating with paraformaldehyde in dioxane or acetic acid solvent; polymerizing in THF (or xylene, DMSO) in the presence of potassium tert-butoxide at 0-80° under ultrasonic wave vibrating for 0.5-10 h. Polyphenylenevinylene derivatives can be obtained under lower temperature, shorter time and with higher reaction yield, and can be dissolved in normal solvents without gels. Thus, poly[[methoxy(octyloxy)-1,4-phenylene]-1,2-ethenediyl] is prepared by the homopolymerization of 1,4-di(chloromethyl)-2-methoxy-5-octyloxybenzene in THF under reflux, at a yield of 81.2%, wherein the monomer is prepared by the dichloromethylation of 1-methoxy-4-octyloxybenzene by paraformaldehyde and concentrated HCl under sonication, with 4-methoxyphenol as the starting material. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Quality Control of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene
