A method of making an organic salt comprising: reacting a polyphenol with a base and optionally a dihaloaromatic compound. The polyphenol is resveratrol; dihydroresveratrol; 4,4′-(but-2-ene-1,4-diyl)bis-2-methoxyphenol; 4,4′-(1,4-butane-diyl)bis-2-methoxyphenol; 1-ethyl-2-methyl-3-(4-hydroxyphenyl)-5-hydroxyindane; 4,4′-(ethane-1,1-diyl)diphenol; 5,5′-methylenebis(2-methoxy-4-methylphenol); 4,4′-methylenebis(5-isopropyl-2-methylphenol); 4,4′-(1-ethyl-2-methyl-1,3-propanediyl)bisphenol; or 5,5′-(ethane-1,1-diyl)bis(2-methoxy-4-methylphenol. The dihaloaromatic compound if present comprises a carbonyl group, a sulfonyl group, a sulfinyl group, or a phosphoryl group. There is a molar excess of the hydroxy groups of the polyphenol relative to halo groups of the dihaloaromatic compound if present. The corresponding phthalonitrile monomers and thermosets made from the organic salts are disclosed.
一种制备有机盐的方法,包括:将多酚与碱反应,可选地与二卤芳烃化合物反应。多酚是白藜芦醇;二氢白藜芦醇;4,4'-(丁-2-烯-1,4-二基)双-2-甲氧基苯酚;4,4'-(1,4-丁二基)双-2-甲氧基苯酚;1-乙基-2-甲基-3-(4-羟基苯基)-5-羟基吲哚;4,4'-(乙烷-1,1-二基)二酚;5,5'-亚甲基双(2-甲氧基-4-甲基苯酚);4,4'-亚甲基双(5-异丙基-2-甲基苯酚);4,4'-(1-乙基-2-甲基-1,3-丙二基)双酚;或5,5'-(乙烷-1,1-二基)双(2-甲氧基-4-甲基苯酚)。如果存在二卤芳烃化合物,则其包括羰基基团、磺酰基、亚磺酰基或磷酰基。相对于二卤芳烃化合物的卤素基团,多酚的羟基存在摩尔过量。还公开了相应的邻苯二腈单体和由有机盐制成的热固性材料。
