Title: Improved manufacture of mercurated hydrocarbons
IPC: C07F3/12
Filed: 1932-08-04
Abstract: Mercurated hydrocarbons are prepared by heating toluene or its higher homologues with mercuric acetate in aqueous solution.  The mercuric acetate may be prepared in situ from mercuric oxide and aqueous acetic acid.  By the use of water as the solvent, the reactants may be employed in approximately the theoretical quantities to produce mono- or poly-mercurated compounds.  The products are useful as seed disinfectants, being then incorporated with a diluent such as talc. According to the examples, mercuric oxide is heated with glacial acetic acid, water, and either toluene, commercial xylol, m-xylene or commercial cymene; the mercurated compound settles out on cooling. For the preparation of a seed disinfectant, the compound or its solution is mixed with talc, tinted with a pigment such as iron oxide, dried if necessary, and ground.
