Nws tau txais los ntawm chlorination thiab condensation ntawm o-chlorobenzoic acid. Ntxiv o-chlorobenzoic acid thiab benzene nyob rau hauv cov tshuaj tiv thaiv lauj kaub, do qhov kub rau 50-70 degree, maj mam ntxiv sulfoxide chloride. Tom qab nce qhov kub thiab txias mus rau 80 degree thiab reflow rau 5h, o-chlorobenzoyl chloride yog chlorinated. Cov tshuaj chlorinated tau ntxiv rau benzene uas muaj txhuas trichloride ntawm qhov kub ntawm 10-20 degree thiab reacted ntawm 20-25 degree rau 5h. Tom qab cov tshuaj tiv thaiv, ncuav rau hauv dej khov rau hydrolysis, ntxiv hydrochloric acid, cais benzene txheej, ntxuav nrog 10 feem pua sodium hydroxide tov, ntxuav nrog dej, chav benzene thiab dej kom txog thaum 2-chlorobenzophenone tau txais.
