The present disclosure relates to a method of immobilizing a phenolic compound having a Mw ≥ 500 g/mol, wherein the method comprises the steps of ionizing the phenolic compound by subjecting it to a base; and contacting, under agitation, the ionized phenolic compound with a cross-linked resin comprising the functionality of -C(=O)-CHXCH2R, wherein X is chosen from the group consisting of Br, Cl, I, CN, OMs, OTs, or OTf, and R is H, CH3 or an branched or unbranched alkyl having 1 to 8 carbon atoms, in the presence of a base and a solvent. The present disclosure also relates to a method of removing phenolic compounds having a Mw ≥ 500 g/mol from a composition comprising compounds having at least one alkoxysilane group. The present disclosure also relates to the use of a method according to the present disclosure as well as to a product, from which at least one phenolic compound having a Mw ≥ 500 g/mol has been removed by a method according to the present disclosure.
本公开涉及一种固定化酚类化合物的方法,该酚类化合物的 Mw ≥ 500 g/mol;在搅拌下,将离子化的酚类化合物与交联树脂接触,交联树脂的官能度为 -C(=O)-CHXCH2R,其中 X 选自 Br、Cl、I、CN、OMs、OTs 或 OTf 组成的组,R 为 H、CH3 或具有 1 至 8 个碳原子的支链或未支链烷基。本发明还涉及一种从包含至少有一个烷氧基硅烷基团的化合物的组合物中去除 Mw ≥ 500 g/mol 的酚类化合物的方法。本发明还涉及根据本发明公开的方法的使用以及产品,根据本发明公开的方法已从该产品中除去至少一种Mw≥500 g/mol的酚类化合物。
