  1. 1. Catalytic synthesis of benign bisphenols

    Kandidat-uppsats, KTH/Kemi

    Författare :Victoria Chu; Emma Lundqvist; Hampus Hagelin; [2022]
    Nyckelord :Bisphenols; Vanillyl alcohol; Friedel-Crafts alkylation; Lewis acid catalysis; Sustainability; Bisfenoler; Vanillylalkohol; Friedel-Crafts alkylering; Lewissyra-katalys; Hållbarhet;

    Sammanfattning : This study analyzes the reactivity and selectivity of Friedel-Crafts alkylations using benzylic alcohols and phenols in the presence of a Lewis acid, to synthesize methoxylated bisphenols as a benign alternative to BPA. The degree of methoxylation on the electrophile appears to affect the yield of the reaction while the degree of methoxylation on the nucleophile appears to affect the selectivity. LÄS MER
