    • The invention comprises a process for preparing a compound having the formula where Z and W are the same or different, and selected from the group consisting of O, NH and NR, where R is H, alkyl, cycloalkyl or aryl, R' is alkyl, cycloalkyl, alkylene, alkyl 3-propionate, aryl or arylene. A is H if either or both of Z and W are not O, but if both Z and W are O, A is (I) or a carbon based heterocyclic component having an amine constituent, or RR''N-, where R'' is the same or different than R and is selected from the same group as R. The process comprises preparing an alkylthio-substituted benzoquinone intermediate by reacting in a first reaction mixture a thiosubstituted aromatic having the formula (II) where X is OH, NH2 or NHR when Z is O, NH or NR, respectively, and where Y is OH, NH2 or NHR when W is O, NH or NR, respectively, with an alkali metal periodate in the presence of a phase transfer catalyst, followed, if A is not H, by reacting the intermediate in a second reaction mixture containing an amine included in the group of amines comprising A, and in the presence of oxygen to obtain the compound. If A is H no second reaction mixture is employed and the intermediate comprises the compound. The invention includes a process for making the composition and the use of the composition in natural and synthetic rubber, and with monomers, gasoline and lubricating oil to inhibit polymerization.
    • 本发明包括一种制备具有下式的化合物的方法,其中Z和W相同或不同,并且选自O,NH和NR,其中R是H,烷基,环烷基或芳基,R'是烷基 ,环烷基,亚烷基,3-丙酸烷基酯,芳基或亚芳基。 如果Z和W都不是O,则A是H,但如果Z和W都是O,则A是(I)或具有胺组分的碳基杂环组分或RR“N - ,其中R' '与R相同或不同,并且选自与R相同的基团。该方法包括通过在第一反应混合物中使具有式(II)的取代的芳族化合物(其中X为OH,NH 2 当Z为O,NH或NR时,分别为NH,NH或NHR,当相转移催化剂存在时,当W为O,NH或NR时,其中Y为OH,NH2或NHR, A不是H,通过使中间体在包含包含A组胺的胺的第二反应混合物中和在氧气存在下反应以获得化合物。 如果A为H,则不使用第二反应混合物,中间体包含该化合物。 本发明包括在天然和合成橡胶中制备组合物和使用组合物以及单体,汽油和润滑油以抑制聚合的方法。
