  • Method of producing paraquinones
    Patent number: 4739062
    Abstract: A new widely-applicable method has been found for synthesis of 9,10-anthraquinones and similar chemical compounds of wide use in industry and pharmacology, by reacting suitable aromatic substrates with activated dicarboxylic acids (more particularly dichlorides) in the presence of metal halides. The special characteristics of the reaction are the good yields, high selectivity, the possibility of operating in a single reactor and the use of starting compounds which are cheap and easily available on the market.

  • Process for preparing 2-hydroxybenzoic aldehydes
    Patent number: 4151201
    Abstract: There is disclosed a catalytic process for preparing, from phenols and formaldehyde 2-hydroxybenzoic aldehydes some of which are new in the art and, more particularly, a high-selectivity process for preparing the aldehydes by direct synthesis from phenols having at least a free ortho position and formaldehyde, in the presence of a catalyst consisting of anhydrous stannous and/or stannic chloride and of an aprotic binder.
