抗氧剂2,2′-亚甲基双(6-壬基对甲酚)是新型大分子量液体双酚类抗氧剂,我们以对甲酚为原料,通过酯化反应、Fries重排反应、傅克酰化反应、羰基Clemmensen还原反应和酸介导的甲醛亲和取代反应合成了2,2′-亚甲基双(6-壬基对甲酚),中间体和最终产物都通过NMR、MS表征确证,以大于90%的总收率实现产品的合成。
抗氧劑2,2′-亞甲基雙(6-壬基對甲酚)是新型大分子量液體雙酚類抗氧劑,我們以對甲酚為原料,通過酯化反應、Fries重排反應、傅剋酰化反應、羰基Clemmensen還原反應和痠介導的甲醛親和取代反應閤成瞭2,2′-亞甲基雙(6-壬基對甲酚),中間體和最終產物都通過NMR、MS錶徵確證,以大于90%的總收率實現產品的閤成。
항양제2,2′-아갑기쌍(6-임기대갑분)시신형대분자량액체쌍분류항양제,아문이대갑분위원료,통과지화반응、Fries중배반응、부극선화반응、탄기Clemmensen환원반응화산개도적갑철친화취대반응합성료2,2′-아갑기쌍(6-임기대갑분),중간체화최종산물도통과NMR、MS표정학증,이대우90%적총수솔실현산품적합성。
Diphenol antioxidant,2,2′-methylenebis(6-nonyl-p-cresol),is a novel liquid diphenol antioxidant with high molecular weight,which was synthesized with crude material p-cresol. The target molecule was achieved by esterification,Fries rearrangement,Friedel-Crafts acylation,Clemmensen reduction and acid-mediated nucleophil-ic substitution reactions. All intermediate and final compounds were fully characterized by NMR and MS,and the total yield is more than 90% in about 4 steps.
