【摘要】：以3-甲基二苯胺為原料,通過親核取代、水解和氧化反應(yīng),獲得了3-甲基-10-羥基-5,10-二氫磷雜吖嗪-10-氧化物。在此基礎(chǔ)之上,經(jīng)過硝化、加氫還原和縮合反應(yīng),得到了一種新型的醌亞胺化合物(PPBQ)。PPBQ具有調(diào)控乙烯基單體乳液聚合反應(yīng)的能力,在單體含量為4mol/L、引發(fā)劑(K_2S_2O_8)濃度為3.7×10~( 3)mol/L、PPBQ與引發(fā)劑的摩爾投料比[n(PPBQ)∶n(K_2S_2O_8)]小于0.8的條件下,能夠獲得平均分子量(Mw)不高于65769、分子量分散度(Mw/Mn)不高于2.49的甲基丙烯酸乙酯乳液及平均分子量小于1000的寡聚體產(chǎn)品,為高固體涂料、聚丙烯酸類阻垢劑、凈水劑的制備提供了一條新的思路。運用紅外、質(zhì)譜和1H和13C核磁等檢測方法,對生成的中間體和產(chǎn)物的結(jié)構(gòu)進行了正確表征,運用紅外、質(zhì)譜和凝膠色譜等檢測方法,對甲基丙烯酸乙酯寡聚體的結(jié)構(gòu)進行了表征。
[Abstract]:By nucleophilic substitution, hydrolysis and oxidation of 3-methyldiphenylamine, 3-methyl-10-hydroxy-5-dihydro-10-dihydrophosphorazine-10-oxide was obtained from 3-methyldiphenylamine. On this basis, nitration, hydrogenation, reduction and condensation were carried out. A new quinone imine compound, PPBQN. PPBQ, has the ability to regulate the emulsion polymerization of vinyl monomers. When the monomer content is 4 mol / L, the initiator K2S2O8 has a concentration of 3.7 脳 10 ~ (-1) (the molar ratio of nPPBQ to initiator [nPPBQW / K _ 2S _ 2O _ 8]) is less than 0.8. The emulsion of ethyl methacrylate with average molecular weight not more than 65769, the dispersion of molecular weight less than 2.49 and the oligomer with average molecular weight less than 1000 can be obtained, which are high solid coatings and polyacrylic acid scale inhibitors. The preparation of water purifying agent provides a new way of thinking. The structure of the intermediate and product was correctly characterized by IR, MS and 1H and 13C NMR, and the structure of the product was determined by IR, MS and gel chromatography. The structure of ethyl methacrylate oligomer was characterized.
