    摘要: A process which can be used to produce an aromatic sulfide compound having the formula of (R.sub.4-n)(X.sub.n)(W)Ar--S--R' is provided. The process comprises contacting, in the presence of a surfactant, a halo-substituted aromatic compound in an aqueous solution with a salt of a mercaptan under conditions sufficient to produce the aromatic sulfide in which the halo-substituted aromatic compound and salt of mercaptan are each present in an amount effective to synthesize the aromatic sulfide wherein R is hydrogen or a hydrocarbyl radical, X is a halogen, n is a number from 0 to 3, W is a substituent, Ar is an aromatic ring, and R' is a hydrocarbyl radical.

    摘要: Alkylphenyl alkyl ethers or alkylphenyl alkyl thioethers, of the formula ##STR1## where U represents O or S; and R.sub.1 -R.sub.6 each independently represent an alkyl or aryl group with 1-6 C atoms, but R.sub.1 -R.sub.5 may each independently represent a functional group other than these, particularly --COOR (R=C.sub.1-4 alkyl), --NO.sub.2, --NH.sub.2, --O--CH.sub.2 --CH.sub.2 --OH, --OH, --CHO, --H, or -halogen;R.sub.1 -R.sub.5 may be bridged by suitable bifunctional substituents, such as, e.g., --(CH.sub.2).sub.x --, or --(CH.sub.2).sub.x --Z--(CH.sub.2).sub.y -- (where Z represents a hetero atom; x=0-7 and y=0-7), or by unsaturated substituents or anellated ring systems; may be produced in high space-time yield by reacting the corresponding phenol or thiophenol with a arylalkyl carbonate at a temperature of 70.degree.-300.degree. C. under elevated or normal pressure, in the presence of a monocyclic, bicyclic, polycyclic, or acyclic amidine as a catalyst.
