N butyl 2 ethoxy thioacridone was prepared from o chloro benzoic acid and p phenetidine by means of Ullman reaction,cyclization,N alkylation and sulfurization.
A new camphol sandaliol was synthetized by selective alkylation of isocamphol and phenol with acidic catalyst, and following hydrogenated in the presence of Raney nickel.
And it mainly includes the action of 1,3-diethylene alkylation and acidyl; the action of addition of carbonyl compound; the action of chlorortrimethys:lane and the reaction of diethy lene.
P - tert - octylphenol (shorten by PTOP), the alkylation product of phenol with diisobutylene(shorten by DIB), has been largely applying in varied fields such as rubbers, oil additives and so on.
